Isolation and characterization of lactic acid bacteria from clarias macrocephalus (African Catfish) for potential probiotic purposes
Lactic acid bacteria (LAB) play an important role in aquaculture to develop microbial control strategies since disease outbreaks are recognized as important constraints to aquaculture production and since the development of antibiotic resistance has become a matter of growing concern.
