The purpose of the study, carried out in the years 2001–2003 was to determine which fungal species inhabited decaying grapevine cuttings during callusing and soon after planting them into pots. The plant material was collected from 5 commercial plantations and 8 cultivars, which were most frequently cultivated. From each plantation and cultivar 20 cuttings with symptoms of the growth inhibition or decay were randomly sampled during the callusing period i.e. March/April (term I) and 2–3 months after planting the cuttings into pots i.e. June/July (term II). The results showed that from affected grapevine cuttings Phomopsis viticola, Botrytis cinerea, Alternaria alternata and Fusarium spp. were isolated most frequently. Moreover, it was found that after planting young cuttings into the pots, numerous isolates of soil borne pathogenes were obtained, among others Cylindrocarpon spp., Phytophthora sp., Rhizoctonia solani, Fusarium spp.

Isolation of some biologically important proteins from natural sources was found to be too expensive or scarcely possible (human proteins). The problem could be solved by expression of heterologous genes. Many biologically active proteins have been successfully expressed in filamentous fungi, some of them, however, at a low level. Thus, improvement of this technique appears to be a very important task. The process comprises several steps. Some of them, such as efficient transformation, vector construction, processing of signal sequences, post-translational modifications and secretion of the expressed proteins, have been intensively investigated. This review presents obstacles and problems encountered in expression of heterologous genes and discusses strategies of development in this area.

Recent literature data suggests that parasitic and fungal diseases, which pose a threat to both human and animal health, remain a clinical, diagnostic and therapeutic problem. Attention is increasingly paid to the role played by natural microbiota in maintaining homeostasis in humans. A particular emphasis is placed on the possibility of manipulating the human microbiota (permanent, transient, pathogenic) and macrobiota (e.g., Trichuris suis) to support the treatment of selected diseases such as Crohn’s disease, obesity, diabetes and cancer. Emphasis is placed on important medical species whose infections not only impair health but can also be life threatening, such as Plasmodium falciparum, Echinococcus multilocularis and Baylisascaris procyonis, which expand into areas which have so far been uninhabited. This article also presents the epidemiology, diagnosis and treatment of opportunistic parasitoses imported from the tropics, which spread across large groups of people through human-to-human transmission (Enterobius vermicularis, Sarcoptes scabiei). It also discusses the problem of environmentally-conditioned parasitoses, particularly their etiological factors associated with food contaminated with invasive forms (Trichinella sp., Toxoplasma gondii). The analysis also concerns the presence of developmental forms of geohelminths (Toxocara sp.) and ectoparasites (ticks), which are vectors of serious human diseases (Lyme borreliosis, anaplasmosis, babesiosis), in the environment. Mycological topics contains rare cases of mycoses environmentally conditioned (CNS aspergillosis) and transmissions of these pathogens in a population of hospitalized individuals, as well as seeking new methods used to treat mycoses.

The measurement of respiration activity of microorganisms in particular aggregate fractions for 3 soils was performed. And an attempt was made to determine the relation between the quantity of bacteria and fungi. The correlation between the size of aggregates and respiration activity of microorganisms was found out.

The objectives of the present study were isolation, identification and characterization of xylanase producing fungi, optimization of medium composition and cultural conditions for xylanase enzyme production using cheaper sources. The fungal strains were isolated from garden soil by serial dilution technique and Aspergillus niger was identified and isolated in pure form. In conformation screening by congo red test, based on the reddish zone of enzyme activity formation in oat spelt xylan agar plates, A. niger was selected and optimized for xylanase enzyme production in solid state fermentation using cheaper sources like wheat bran, rice bran, soya bran, ragi bran and saw dust. Maximum enzyme activity was observed in wheat bran (9.87 U/ml). The use of wheat bran as a major carbon source is particularly valuable because oat spelt xylan or birch wood xylan are more expensive. The effects of time course, incubation substrate, inoculum size, moisturizing agent, moisture content, temperature and volume of fermentation medium on the production of xylanase were studied. The maximum xylanase production (12.65 U/ml) was observed at optimized condition, incubation temperature of 28°C after 6 days of incubation period while minimum production (9.38 U/ml) at unoptimized condition. The maximum production of enzyme was found to be in wheat bran when the volume of fermentation medium was kept as 10 g/250 ml conical flasks, with mineral solution as moisturizing agent and moisture ratio 1:0.7. Thus the present study proved that the fungal strain A. niger used is highly potential and useful for xylanase production.
