title: Studies on N-acetylglucosaminidase activity produced by Streptomyces hygroscopicus.
abstract: Following growth on chitin-containing media the actinomycete, Streptomyces hygroscopicus produces N-acetylglucosaminidase. When the organism was grown in submerged culture on chitin-containing media, at 30 degrees C, production of the N-acetylglucosaminidase activity has been shown to increase to a maximum at around day 18. Following electrophoretic analysis of culture filtrates and subsequent zymogram staining with fluorescent substrate analogues, at least three general pools of N-acetylglucosaminidase activity were detected. These were named NA1, NA2 and NA3. In addition, a potential chitinase was also identified. The N-acetylglucosaminidases, referred to above as NA1 and NA2, were separated and their enzymatic properties were investigated.
