Title

ISOLATION AND SCREENING OF ANTIBACTERIAL AND ENZYME PRODUCING MARINE ACTINOBACTERIA TO APPROACH PROBIOTICS AGAINST SOME PATHOGENIC VIBRIOS IN SHRIMP LITOPENAEUS VANNAMEI

Abstract

 The application of new PROBIOTICs is a good strategy in the BIOLOGICAL CONTROL of infectious diseases in aquaculture. Approximately 100 MARINE ACTINOBACTERIA isolates were obtained from 10sediment samples of SHRIMP farms. Heat treatment of sediment samples resulted in a selective reduction of the non actinobacterial heterotrophic microflora. Starch nitrate agar medium exhibited more efficacy than glycerol arginine agar medium for isolation. Twenty seven percent of actinobacterial isolates showed antagonistic activities against pathogenicVibrio spp. All the antagonistic isolates showed the typical morphology of genusStreptomyces. Exoenzymatic activity screening showed that 44 %, 26%, 37% of antagonistic isolates represented amylase, lipase and protease activities, respectively. MNM-1400 strain exhibited highest antagonistic and exoenzymatic activity. The pathogenicity experiment revealed that MNM-1400 strain did notcause disease in LITOPENAEUS VANNAMEI larvae. Extraction of produced antibacterial compounds by MNM-1400 strain showed that the active constituent didn’t have non polar property. Morphological, physiological and biochemical identification confirmed that MNM-1400 strain belonged to the genus streptomyces.Phylogenetic analysis by 16S rRNA gene sequencing showed a high similarity between MNM-1400 strain andStreptomyces californicus (similarity: 99%).These results suggest thatthe MNM-1400 strain can be considered as a potential PROBIOTIC in aquaculture.
