Screening of lactic acid bacteria from the gut of Chrysichthys nigrodigitatus for use as probiotics in aquaculture production
Lactic and bacteria (LAB) namely Lactobacillus plantarum l and L. pentosus were isolated from the gut of Chrysichthys nigrodigitatus using Bergey's manual of determinative bacteriology (API- 50 CHL, BioMerieux). They are beneficial and safe organisms that improves disturbances of the indigenous microflora and host's immune system. Gut removed from fish samples were dissected and divided into 3 regions: fore gill, mid gut and hind gut. Lactobacillus plantarum l and L. pentosus were isolated from these regions using MRS (de Man, Rogosa and Sharpe) agar and broth after subsequent culture and sub culture to obtain discrete colonies. They were characterized as gram-positive, non-motile, catalase negative and non-sporulating bacteria.
