Abstract
Bioactive potential of bacterial endosymbionts isolated from Lamellodysidea herbacea, marine sponge from the coast of South Andaman, India, against human bacterial pathogens
Highlights
The quest for novel biomolecules with potential therapeutic value always remains a challenge as the resistance by pathogenic microorganisms is increasing day by day
Eight isolated bacterial strains from the sponge were screened for bioactivity against human pathogens Escherichia coli (MTCC 443), Bacillus cereus (MTCC 430), Bacillus subtilis (MTCC 121), Listeria monocytogenes (MTCC 839), Staphylococcus aureus (MTCC 3160) and Salmonella enterica typhimurium (MTCC 1252) and only two strains CAB1 and CAB38 exhibited activity
A total of 10 bacterial strains were isolated from L. herbacea and only eight of them could be sub-cultured in the laboratory conditions
Summary
The quest for novel biomolecules with potential therapeutic value always remains a challenge as the resistance by pathogenic microorganisms is increasing day by day. The symbiotic microorganisms of sponge are highly diversified and include archaea, bacteria, cyanobacteria, green algae, red algae, diatoms, dinoflagellates and fungi and constitute even up to 40%–60% of the sponge biomass (Hentschel et al, 2001; Lee et al, 2001; Maldonado et al, 2005; Taylor et al, 2007; Zeng et al, 2013) These microbial associates remain in high densities with the sponge tissue and have a significant influence on the life cycle of its host sponge (Taylor et al, 2007; Webster and Taylor, 2012).
