The studies aimed at determining the influence of acetic acid concentrations on Salmonella spp. in microbiological media and on turkey carcasses. The average number of bacteria in control samples without the supplement of acetic acid was for S. Enteritidis 1.3 · 10⁸, S. Anatum 1.9 · 10⁸ and S. Typhimurium 2.3 · 10⁸. Acetic acid in agar medium at 0.1% concentration inhibited growth of studies Salmonella strains entirely. In case of acetic acid concentration of 0.05% the number of bacteria compared to the controls decreased by 6 logarithmic cycles. In case of 0.03% concentration the number of S. Anatum decreased by 5 logarithmic cycles while S. Enteritidis and S. Typhimurium by 4 logarithmic cycles. In the presence of 0.02% acetic acid S. Enteritidis and S. Typhimurium grew in numbers that were within the same logarithmic range, only S. Anatum decreased in number by one logarithmic cycle as compared to the controls. The results of studies obtained after immersing elements of turkey carcasses in acetic acid indicate that the recovery of Salmonella spp. from the samples depends on the inoculum of those bacteria in poultry carcass surface. In case of contamination with 10 colony forming units (cfu) of Salmonella spp. on the surface of a turkey carcass element and immersing it for 15 minutes in 1%, 1.5% and 2% acetic acid solutions a decrease in the number of samples from which those microorganisms were recovered as compared to the number of control samples was recorded. In case of contamination with 10² cfu on the turkey carcass surface and immersing it in tested 1%, 1.5% and 2% solutions of acetic acid for 15 minutes no influence on detection of Salmonella spp. was recorded. The inhibitory influence of acetic acid on Salmonella spp. was much more pronounced in case of the microbiological medium than in case of poultry carcasses on which satisfactory elimination of Salmonella spp. was not achieved.

Seed infection with Alternaria spp. is an important source of severe carrot diseases. The aim of the study was to evaluate the effects of carrot seed treatments with acetic acid, grapefruit extract and volatile compounds of fir (Abies alba Mill.) and thyme (Thymus vulgaris L.) essential oils on their germination, vigour and health. Seeds of two samples were soaked for 30 min in 0.5, 1 and 2% acetic acid, 0.5 and 1% Biosept Active (33% of grapefruit extract), or treated for 72 h or 96 h with volatile compounds of fir and thyme oils individually (10 µl), and jointly (5+5 µl). Controls were untreated seeds and seeds soaked in distilled water. Acetic acid effectively controlled A. alternata and A. radicina in both samples, and did not affect adversely seed germination, however, at the highest concentration deteriorated seed vigour. Biosept Active was less effective, however at 1% concentration decreased seeds infestation with A. alternata in sample I, and at concentrations of 0.5 and 1% reduced percentages of seeds infested with A. alternata and A. radicina in sample II. Essential oils treatments in some cases favoured growth of A. dauci and A. radicina.

The amount of and changes in the products of protein hydrolysis (TCA-soluble and TCA-insoluble biuret positive products, brine extractable protein, non-protein nitrogen, amino acid nitrogen and others) were examined in salted flesh of headed and gutted Baltic herring immersed in 16% NaCl brine with the addition of acetic acid (0, 1, 2, 3, 4, 5, 6, 7%), as well as in brine itself, after one and two weeks of storage at a temperature of 8 ± 1°C. The addition of acetic acid into brine accelerated proteolysis in flesh noticeably, at the same time retarding diffusion of muscle protein into brine. After the first week of fish maturation, the maximum proteolysis was observed at a pH of 3.8, and after the second week of maturationat a pH of 4.2 to 4.8.

We previously discovered that a 4-wk course of indomethacin delivered to rats with acetic acid ulcers resulted in production of "unhealed gastric ulcers" that persisted for up to 12 wks after treatment cessation. The present study examined the mechanism underlying such "unhealed gastric ulcers" with biochemical and histological procedures. "Unhealed gastric ulcers" were induced with a 4-wk indomethacin treatment (1 mg/kg, twice daily) in rats with acetic acid ulcers. Two and 4 wks after treatment cessation, ulcer size was significantly larger in rats receiving indomethacin compared with control animals. Ulcerated tissue prostaglandin E2 levels were significantly lower during indomethacin treatment, but the levels tended to increase after treatment cessation compared with levels measure in the group receiving vehicle. Myeloperoxidase activity levels were significantly higher during indomethacin treatment; such levels persisted after treatment cessation. Histologically, greater degrees of fibrosis and neutrophil accumulation, as well as a lesser degree of angiogenesis were observed in the "unhealed gastric ulcers" compared to ulcers that healed in a normal fashion. It was concluded that severe fibrosis, persistent neutrophil infiltration, and poor angiogenesis in the ulcer base might represent factors involved in the mechanism underlying production of "unhealed gastric ulcers".

Fluorescein efflux from S. Cerevisiae cells was measured to study the peculiarities of fluorescein transport system, which is important for yeast resistance to certain drugs and weak organic acid preservatives. Glucose-independent and glucose-stimulated fluorescein effluxes were characterized using iodoacetate, cyanide and orthovanadate, inhibitors of glycolysis, electron transport chain, and ATPases, respectively. It is supposed that in glucose-free medium fluorescein extrusion is ATP-dependent and the energy for this efflux is mainly provided by respiration. In glucose-containing medium, glycolysis plays a critical role for extrusion of fluorescein. The results indicate that acetic acid inhibits the fluorescein efflux from yeast cells. The inhibition constant of glucose-stimulated fluorescein efflux is significantly lower in parental strain than in two mutants defective in PDR12 (ABC-transporter Pdr12p) or WAR1 (transcription factor of Pdr12p). It can be suggested that the membrane protein Pdr12 is involved in fluorescein extrusion from the yeast cells, but component(s) other than Pdr12p is (are) also important.

There is an existing need for the development of rapid and easy-to-perform methods for analyzing chemical composition of soil basing on simultaneous extraction of many elements in a single solution. Furthermore, it is desirable that mineral concentration determined in soil using these methods should be significantly correlated with its content in plants. Many researches indicated that soil concentration of heavy metals and trace elements after extraction using 0.01 M CaCl2 did not reflect its content in vegetable plants.. The aim of the research was to determine the relation between soil content of: Al, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, Ti, V and Zn extracted in 0.03 M CH3COOH as well as 1 M HCl and its content in carrot storage roots. In 2008–2009 studies were carried out on soil samples after carrot cultivation (from 0–30 cm, 30–60 cm and 60–90 cm layers) as well as on carrot storage roots grown on the same soil site. In total, analysis of chemical composition (with respect to the content of tested elements) comprised: 112 samples of carrot storage roots, 112 soil samples from 0–30 cm layer as well as 48 soil samples from 30–60 cm and 60–90 cm layers. Higher applicability of soil extraction with 0.03 M CH3COOH (commonly used for macro element chlorides and boron determination) in comparison to extraction with 1 M HCl was demonstrated in reference to the estimation of the relation between soil and carrot content of: Al, B, Ba, Cd, Cr, Cu, Li, Ni, Sr, Ti and Zn. Application of 1 M HCl gave relatively better results when compared to the extraction with 0.03 M CH3COOH with respect to calculated values of correlation coefficient for Co, Fe, Mn, Mo and Pb content in soil and carrot. Content of Co, Mo, Pb and V in soil after extraction using 0.03 M CH3COOH was below the limits of its detection using ICP-OES spectrometer. No relation was found between vanadium content in soil (analyzed after extraction with 1 M HCl) and its content in carrot storage roots.
