The use of sporangiospores from a 20-day culture for inoculation enabled us to obtain yeastlike cells of strain Mucor hiemalis F-1431 (for which capacity for dimorphic growth was not previously studied) by cultivation in liquid medium under aerobic conditions. The carbohydrate composition of the fat-free biomass of the mycelial and yeastlike forms grown in(More)
Up-to-date information concerning the chemical structure and properties of trehalose, its natural occurrence and biological functions in plants, fungi, and prokaryotes, as well as its practical application, mainly in medicine and biotechnology, are reviewed. A special section deals with the role of trehalose and other protective polyols in stress processes(More)
Qualitative and quantitative differences were found between the lipids of cell walls (CW), of whole mycelial cells, and of dormant cells of mucoraceous and ascomycete fungi. Thus, whole mycelial cells (WC) contained more lipids than CW. Unlike sporangiospores and conidia (exogenous dormant spores), zygotes were found to have the highest content of(More)
This article deals with a new research area related to mycology and the food industry. It is concerned with the strategies used by ascomycete mycelial fungi to utilize and colonize food items. The data of scanning and transmission electron and light microscopy revealed that fungi growing on such food items as cheese and sausage are characterized by the(More)
The review describes the natural biopolymer lignin, which is second in plant biomass abundance. It is evident now that lignin is considerably undervalued and insufficiently studied in the applied area. The review focuses on the history of the lignin discovery, methods for its extraction from plant objects, its biodegradation by fungi, the enzymes degrading(More)
Comparative analysis of germination of asexual sporulation spores (conidia and sporangiospores) and of specific features of dormancy release was carried out for ascomycete mycelial fungi Aspergillus tamarii VKM F-64 and A. sydowii VKM F-441, as well as for zygomycete fungi Cunninghamella echinulata VKM F-663 and Umbelopsis ramanniana VKM F-582. The spores(More)
During cultivation of the filamentous fungus Lentinus tigrinus on a medium containing lignin, a high oxygen content stimulated the growth of the fungus and contributed to the yield of lipids. A high content of phosphatidic acid and a reduction in the level of phosphatidylethanolamine and phosphatidylserine were first detected in the composition of(More)
The number of sporangiospores used as inocula may significantly affect the development of the morphogenetic programs in mucoraceous fungi, including manifestations of dimorphism. In order to assess the physiological state of sporangiospores differing in their viability and germination patterns, lipid composition of sporangiospores from 6-, 14-, and 20-day(More)
The addition of an antioxidant (2-ethyl-6-methyl-3-hydroxypyridine hydrochloride) to a culture of the fungus Lentinus tigrinus growing on a medium with lignosulfonate inhibited growth and changed the composition of cell phospholipids. The ratio of lipid messengers also changed, the phosphatidic acid level decreased, and the content of phosphatidylinositol(More)
The main stages in the production of biodiesel fuel from lipids of filamentous fungi belonging to the order Mucorales are described. Fungi of the family Cunninghamellaceae have been screened; the lipogenic activity of the examined strains has been assessed; and a producer generating up to 50% of lipids, represented by triacylglycerols, has been found. The(More)
