Abstract:

Two lactic acid bacterial stains having the ability to produce protease were isolated and screened from the gastrointestinal tract of duck with the aid of skim milk medium. The stains were identified as Lactobacillus casei subsp., Rhamnosus and Lactobacillus casei through the systematic investigations of morphology, staining reaction, physiological and biochemical characteristics and 16S rRNA sequences analysis.

Key words: Lactobacillus, producing protease, screening, identification
