Investigated ability to growth and synthesis extracellular proteinase on the unstable and fixed fibers at 4 kinds deuteromycetes: P. рuberullum, Ph. verrucosa, A. flavus, A. versicolor. All listed kinds deuteromycetes used for growth and development micellium both natural and the fixed muscle and collagen, differences consist in growth rates on these substrates. The maximal growth rate on a nutrient medium with a muscle is established at Ph. verrucosa and has made 4,4 mm / day On the fixed muscle  the greatest value of growth rate describe deuteromycetes also at this kind deuteromycetes also has made 3,6 mm/day. The maximal values of an index on collagen are established at Ph. verrucosa, and on the same fixed substratum  at A. versicolor. On nutrient medium with the fixed muscle any of the investigated kinds deuteromycetes did not synthesize some extracellular enzymes.
