1. Purificação e caracterização de uma ß-N-acetillhexosaminadase extraída do mamífero marinho Sotalia fluviatilis
This report shows 2232 times purification of a βNAcetylhexosaminidase from hepatic extracts from the sea mammal Sotalia fluviatilis homogenate with final recovery of 8,4%. Sequenced steps were utilized for enzyme purification: ammonium sulfate fractionation, Biogel A 1.5 m, chitin, DEAESepharose and hydroxyapatite chromatographies. The protein molecular

2. FORMATION OF “PROTOPLASTS” OF STAPHYLOCOCCUS AUREUS WITH A FUNGAL N-ACETYLHEXOSAMINIDASE1
Hash, John H. (Lederle Laboratories, Pearl River, N.Y.), Marcia Wishnick, and Philip A. Miller. Formation of “protoplasts” of Staphylococcus aureus with a fungal N-acetylhexosaminidase. J. Bacteriol. 87:432–437. 1964.—“Protoplasts” of Staphylococcus aureus were obtained when cells were treated with a fungal N-acetyl-hexosaminidase in hypertonic s

3. Interaction of Ammonium, Glucose, and Chitin Regulates the Expression of Cell Wall-Degrading Enzymes in Trichoderma atroviride Strain P1
Chitinolytic and glucanolytic fungal cell wall-degrading enzymes have been suggested to be primary determinants of biocontrol by Trichoderma spp. We examined the effects of ammonium, glucose, chitin, and chito-oligomers on transcription of specific genes and secretion of fungal cell wall-degrading enzymes. The genes ech42, nag1, and gluc78 were examined, as
