Influence ofsome technological parameters of cultivation ofproducers Cryptococcus albidus, Eupenicillinum erubescens, Bacillus sp. on the process of synthesis of extracellular enzyme alpha-L-rhamnosidase has been studied. The authors have determined optimal sources of carbon (0.2-0.3% rhamnose) and nitrogen (0.2% sodium nitrate

Extensive screening for a robust producer of α-L-rhamnosidase activity from well-defined strains of filamentous fungi, including multifactorial optimization (inducers, cultivation conditions) was accomplished. Enzyme production of the optimal producer Aspergillus terreus (non-toxigenic) was scaled up to 50L. α-L-Rhamnosidase, which was
