Several biotechnological aspects regarding the increase in transglutaminase biosynthesis yield were studied. The Streptomyces sp. strains used in this study, coded MIUG 6P, MIUG 7P and MIUG 13P, were isolated from soils from the East Antarctic coast. These had the best results in terms of transglutaminase synthesis, thus confirming the results of a previous study concerning the isolation and strains selection of good transglutaminase producers.

The aim of this study was to evaluate the capacity of certain bacterial and fungal strains - isolated from the dairy industry wastewater - to biodegrade the organic compounds such as casein, lactose and lactic acid similarly to those which determine the organic pollution. The strains able to rapidly biodegrade organic compounds were identified and screened for the inoculum preparation which is afterward tested for the aerobic biological treatment
