  1. Abbreviations: + Positive, Negative, ± Doubtful, Blank cells no data available. L-asparaginase, gelatinase, cellulose, protease and α–amylase were produced by Streptomyces sp. strain NEAE-94 while chitosanase, lecithinase and uricase were not produced. Maximum NaCl tolerance (5%, w/v).The optimal growth temperature was 30°C and optimal pH was 7.0. It exhibited positive antimicrobial activities against Staphylococcus aureus, E. coli, Bacillus subtilis and Pseudomonas aeruginosa. Nitrate reduction, coagulation and peptonization of milk were positive
