Optimization of Nutrients and Culture Conditions for Alkaline Protease Production Using Two Endophytic Micrococci: and .

An endophytic species of was isolated from leaf (syn. ) and screened for protease production with five other species of . Data indicated that endophytic AE-6 MCC 2184 and DSM 21948 showed efficient protease production potential and secreted active protease at high salt (10%), temperature (40 °C) and in wide range of pH 8-10.

Description of Micrococcus aloeverae sp. nov., an endophytic actinobacterium isolated from Aloe vera.

A yellow Gram-stain-positive, non-motile, non-endospore -forming, spherical endophytic actinobacterium, designated strain AE-6(T), was isolated from the inner fleshy leaf tissues of Aloe barbadensis (Aloe vera) collected from Pune, Maharashtra, India. Strain AE-6(T) grew at high salt concentrations [10% (w/v) NaCl], temperatures of 15-41 °C and a pH range of 5-12. It showed highest (99.
