Abstract

Citrococcous paritis was isolated and identified as an alkali-stable protease using 16S rRNA sequencing analysis. After 48 h of incubation in the CPYA medium with 1% casein and 1% yeast extract (pH 10.0), an isolate of the detergent factory (DF-10) showed maximum protease activity of 18.10 U/ml when haemoglobin was used as substrate. The alkaline protease showed optimal activity at pH 10.0 and a temperature of 50°C. The newly isolated C. paritis strain was efficiently characterized for alkaline protease production and blood stain removal, and therefore can be used as a suitable candidate in the detergent and leather industry.

Keywords

Citrococcous paritis, Alkaline protease, Casein, Detergent, Alkali stable.
