This review paper covers the recent developments in the field of funga
l physiology and biochemistry, particularly the recent research on spo
rogenesis and the chemical composition of cells and cell walls. Of spe
cial interest are modern biotechnologies developed on the basis of the
se data and aimed at obtaining enzymes, pigments, and other biological
ly active compounds, including medical drugs and biopesticides. Emphas
is is placed on the environmentally friendly and economical character
of these biotechnologies, which make it possible to obtain substances
formerly isolated from plants and animals.
