Background. Salted fish products are popular in many countries around the world. Salting is one of the oldest techniques for fish preservation, and is essentially intended to increase the shelf-life of the product depressing water activity by means of dehydration and salt uptake by the fish muscle. However, the current demand for salted fish is driven more by the flavour of the product than for preservation purposes. Vacuum-packaging represents a static form of hypobaric storage. It is widely used in the food industry because of its effectiveness in reducing oxidative reactions in the product at relatively low cost. Low temperature storage is one of the primary methods to maintain fish quality, based on the reduction in the rates of microbiological, chemical and biochemical changes. Material and methods. Fresh Golden mullets were rapidly beheaded, scaled, gutted and immediately washed with tap water then, samples were taken to the laboratory in ice box for chemical and microbial analysis of fresh fish, other samples were put in the brine (6 liter water and 2160 g salt was used for brine solution). After 14 days of brining, fish were taken out of brine solution and drained, then they were Vacuum Packed and labelled (each pack contained two fish about 1500 g weight). Ali the packs were stored in a refrigerator 4°C. Some quality aspects including Total Volatile Nitrogen (TVN), Peroxide Value (PV), Thiobarbituric Acid (TBA), Total Viable Count (TVC), Halophilic Bacteria (HB) and presence of Clostridium Botulinum were determined in fresh mullets, fresh brined mullets after 14 days of brining, and in (Vacuum Packed) VP samples stored at 4°C at intervals of 30, 60 and 90 days. Results. TVN increased from ten mg/100 g in fresh brined after 14 days to 30.80 mg/100 g in VP brined Golden mullet after 90 days of storage at 4°C, PV increased after brining from 1.50 meq/kg in fresh brined to 28.90 meq/kg in VP brined Golden mullet after 90 days of storage at 4°C, TBA increased from 0.07 mg MDA/kg in fresh brined to 0.10 after 60 days and then, decreased to 0.09 mg MDA/kg in VP brined Golden mullet after 90 days of storage and TVC decreased from 4.70 log CFU/gr in fresh brined to 4.40 log CFU/ gr after 30 days and then, increased to 5.70 log CFU/gr in VP brined Golden mullet after 90 days of storage at 4°C, FIB increased from 4.55 log CFU/gr in fresh brined to 6.30 log CFU/gr after 90 days of storage period at 4°C and exceeded the permissible level. Clostridium botulinum toxin was not detected in any of the samples throughout the storage. Conclusions. The results from this study clearly suggested that a combination of brining, vacuum packaging and storage at refrigerated temperature prolongs the shelf-life of Golden mullet to a great extent. Our findings revealed that the longest shelf-life was for VP brined Golden mullet stored at 4°C is 30 days.

Rising environmental concerns toward the use of synthetic chemicals as well as global acceptance of natural products has emphasized the need for exploring novel and sustainable sources of eco-friendly dyes for the textile sector. Our study was conducted to explore the natural colorant potential of black carrot (Daucus carota L.) plant residue for textile processing and optimizing conditions for cotton dyeing. Cotton fabric was dyed using black carrot-based dye, extracted in varying media. The results revealed that black carrot colorants produced darker shades when extracted in acidified methanol media. Excellent color strength of cotton fabrics were found at 70°C by coloring for 55 minutes using 4.0 g of salt (NaCl) as an exhausting agent. The bio mordants as well as chemical mordant were employed to improve color strength properties. In the case of chemical mordanting, 6% tannic acid and 8% iron sulphate as pre-mordant and 8% tannic acid and 2% iron sulphate as post-mordant showed maximum color strength values. Similarly, using bio mordanting, 2% of turmeric (Curcuma longa L.) and 6% of henna (Lawsonia inermis L.) extracts as pre-mordant, as well as 8% of turmeric and 4% of henna extracts as post-mordant showed maximum color strength values. Dyed cotton fabrics exhibited best color fastness properties in term of light, washing, dry and wet rubbing fastness.

Background. Captures of Gymnura altavela from the Syrian marine waters allowed to improve knowledge of size at first sexuality of males and females, reproductive period and fecundity. Materials and Methods. In all, 114 specimens were measured for disk width (DW) and weighed. Sexual maturity was determined in males from the length of claspers and aspects of the reproductive tract, and in females from the condition of ovaries and the morphology of the reproductive tract. Hepatosomatic index (HSI), gonadosomatic index (GSI) were calculated in males and females, and their variations related to size were considered in all categories of specimens. To investigate the embryonic development and the role of the mother during gestation, a chemical balance of development (CBD) was determined, based on the mean dry mass of fertilized eggs and fully developed oocytes. Test of normality was performed by using Shapiro–Wilk’s test, with P < 0.05. Tests for significance (P < 0.05) were performed by using ANOVA, Student t-test and the chi-square test. The linear regression was expressed in decimal logarithmic coordinates. In the relation mass versus total length and liver mass versus total length, comparisons of curves were carried out by using ANCOVA. Results. Females significantly outnumbered males throughout the year. Size at sexual maturity occurred for males at 771 mm DW and for females at 961 mm DW, and maximum size reached 893 mm DW and 1342 mm DW for males and females, respectively. Size at birth ranged between 281 and 367mm DW. Relations size (DW) versus total body mass (MT) did not show significant differences between males and females, relations size (DW) versus liver mass (ML) were significantly different between males and females suggesting that liver plays a more important role in life cycle of the latter. HSI increased with size of specimens especially in females. Similar patterns were observed for GSI in males and females. Females with active vitellogenesis were found throughout the year, and females carrying developing embryos in spring and in autumn, suggesting two gestation periods each year. CBD reached 22.3 and showed that G. altavela is a matrotrophic species. Ovarian fecundity was significantly higher than uterine fecundity, and litter size ranged between 1 and 4. Conclusion. The reproductive biology of G. altavela from the Syrian coast showed that a sustainable population is established in the area. The species develops K-selected biological characteristics as specimens from different marine areas and other elasmobranch species, it explained why it is endangered in the area.

In developing countries, good-quality water is contaminated due to the disposal of untreated municipal and industrial wastewater (WW) into natural water reservoirs. Most of the wastewater is not treated properly according to international standards, and usually is disposed of and/or utilized for irrigation without appropriate treatment. The main hurdles in providing wastewater treatment (WWT) in developing countries include high costs, and the poor design, installation, and operation of conventional WWT systems. Therefore, the present study explores the maize cobs trickling filter-based (MCTF) low-cost WWT option for developing countries like Pakistan, India, and Bangladesh. In this regard, indigenous media trickling filter was designed and developed using maize cobs as packing material for biofilm growth. The MCTFWWT system was continually operated and monitored for six months at constant hydraulic wastewater loading of about 113±2 m3 per m2 per day. The experimental data covers winter and summer seasons with temperature variations from 23ºC to 43ºC. System performance was evaluated by means of various WWT parameters, including biological and chemical oxygen demands (BOD5 and COD), total suspended and dissolved solids (TSS and TDS), turbidity, and color – before and after WWT. Experimental results showed that the MCTF-WWT system successfully removed about 79% BOD and 75% COD on average. The key reason for effective BOD and COD removal was rapid development of microbial film (within the first two weeks). Furthermore, the MCTF-WWT system removed 42-46% TSS, 28-30% TDS, 43-46% turbidity, and 33-37% color. The study concludes that the MCTF-WWT system is an effective and economical WWT option for irrigation/agricultural applications in developing countries.

The purpose of this study was to investigate possible alterations in acid-base balance parameters and the coagulation profile in neonatal diarrheic calves. Twenty neonatal diarrheic and 20 clinically healthy neonatal calves aged between 1 week to 10 days were used. All blood samples were taken on the third day from the onset of diarrhea symptom. Venous blood samples were collected from each animal to determine platelet numbers, pH, pCO₂, pO₂, HCO₃⁻, BE, O₂SAT, ctCO₂ and electrolytes (K⁺, Na⁺ and Cl⁻). Plasma samples were collected from each animal for the measurement of prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), the concentrations of fibrinogen, D-dimer and the activity of antithrombin III (AT III). Blood pH (7.19), BE (-10.6 mmol/l), HCO₃⁻ (25.15 mmol/l), pO₂ (3.33 kPa), O₂SAT (24.12 %) were significantly lower and serum concentration of K⁺ (6.55 mmol/l) was significantly higher in diarrheic calves. These changes indicate the state of uncompensated metabolic acidosis with accompanying hyperkalemia. TT (32.05s) and APTT (39.9s) values were more prolonged in calves with diarrhea than in the control group. D-dimer (587.25 μg/l) concentrations were significantly increased while a visible drop in AT III (103.75%) activity and platelets counts (598 x10⁹/l) were observed in diarrheic group of calves. The results suggest that a consumptive type of disseminated intravascular coagulation (DIC) developed in diarrheic calves.

Soil samples from petroleum-contaminated soil were collected from 25 different petroleum filling stations and automobile workshops in the district of Swat, Khyber Pakhtunkhawa, Pakistan. A total of seven bacterial genera were isolated. All of the isolates were Gram-positive bacteria. The genera identified by the culture and cell morphological characteristics were: Bacillus, Streptococcus, Staphylococcus, Micrococcus, Corynebacterium Arthrobacter, and Streptomyces. Lipolytic and saline activities of the selected isolates were studied. Among the isolates, Arthrobacter, Staphylococcus, Bacillus, Micrococcus, Corynebacterium, and Streptomyces produced lipase enzymes, while no lipase was produced by Streptococcus. Dense growth of Bacillus and Streptococcus was observed at 1% NaCl. Dense growth of Streptomyces was observed at strength of 2% NaCl. At 3% NaCl concentration, dense growth of Staphylococcus, Micrococcus, Corynebacterium, and Arthrobacter was observed, indicating that they were moderately halotolerent. In our study, Bacillus, Arthrobacter, and Streptomyces showed optimum growth at pH 8.0, and Streptococcus, Staphylococcus, and Micrococcus showed optimum growth at pH 7.0. Only Corynebacterium showed optimum growth at pH 9.0, indicating that it is tolerant of higher pH conditions.

The current investigation was undertaken to assess the toxic potential of synthetic insecticides (K.Othrin and bio-max) and botanical extracts (Mentha royleana L. and Artemisia absinthium L.) against Tribolium castaneum in the laboratory. Different concentrations of insecticides and botanical extracts were used following complete randomized block design. The results indicated that the toxic effects were directly proportional to concentrations of insecticide and botanical extracts. Higher concentrations had more resilient toxicity than lower concentrations. Among the tested insecticides, Biomax (Chlorpyrifos) showed >90% and K-Othrin (Deltamethrin) <80% mean toxic effect at 2% concentrations. In the botanical extract, Mentha royleana toxicity at 5% concentration is > 90% as compared to Artemisia absinthium against T. Castaneum. The results could be helpful in designing an effective management plan for the control of T. castaneum.

Water pollution has become a major environmental concern for public and environmental health in developing countries. Water resources are being contaminated mainly due to mixing of domestic, municipal, and industrial wastewaters. The wastewater management and treatment situation is deplorable mainly because of financial constraints, the unavailability of technically trained human resources, and electricity shortages. Moreover, there is a challenge for the scientific community and wastewater management experts to explore cost-effective, simple, reliable, and efficient wastewater treatment systems. Therefore, the present review highlights the option of trickling filter (TF) systems for wastewater treatment in developing countries like Pakistan, India, Bangladesh, and African regions, etc. In addition, the solutions to the operational/performance issues of the TF system are explored and discussed in greater detail for designing/construction of new TF systems and retrofitting the existing TFs.

In the present research, a “green” recipe was used to produce innovative phytogenic magnetic nanoparticles (PMNPs) from leaf extract of Fraxinus chinensis Roxb without employing any additional toxic surfactants as capping agents. The convenient reaction between metal salt solution and plant biomolecules occurred within a few minutes by color changes from pale green to intense black, hinting at the production of magnetic nanoparticles (MNPs). The formation of PMNPs was verified by employing different techniques such as UV-visible spectrophotometry, Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X-ray (EDX). The fabricated PMNPs were further utilized as a catalyst for removing toxic dyes, i.e., Crystal violet (CV) and Eriochrome black T (EBT) from aqueous solutions in the presence of hydrogen peroxide (H2O2). The concentrations of CV and EBT were calculated using ultraviolet-visible (UV-vis) spectroscopy throughout all the experiments. The results indicated that PMNPs showed >95% removal of both dyes within 10 min of contact time over a wide range of concentration, 10-300 mg/L. The degradation kinetics were also investigated using first- and second-order rate equations, and the results indicated that kinetic data of both CV and EBT followed first-order degradation rate. Moreover, the removal efficiency of the fabricated PMNPs was alsocompared with chemically synthesized magnetic nanoparticles (CSMNPs), and the results indicated that our fabricated PMNPs were more effective in terms of extent and speed to remove dyes. Finally, we have also proposed a possible removal mechanism. Altogether, the developed “green” recipe can easily be implemented to produce potentially biocompatible and non-toxic PMNPs for treatment of wastewater and can also easily be employed in low-economy countries.
