10.22376/ijpbs.2019.10.1.p1-12 Volume 5 Issue 4 2014 (October - December) The present work was conducted to isolate the gut bacteria of lessThan i greaterThan Artemia lessThan /i greaterThan and to use them as probiotics to control the bacterial pathogens in aquaculture systems. In the present study, two of bacterial species were isolated from the gut of lessThan i greaterThan Artemia lessThan /i greaterThan which was collected from Puthalam saltpan (Kanyakumari, India). Among the gut isolates of lessThan i greaterThan Artemia lessThan /i greaterThan , best two species, lessThan i greaterThan Alteromonas lessThan /i greaterThan sp. and lessThan i greaterThan Acetobacterium lessThan /i greaterThan sp. were selected. These two isolates were tested for its efficiency and antagonistic activity against V lessThan i greaterThan ibrio harveyi lessThan /i greaterThan and lessThan i greaterThan Alteromonas lessThan /i greaterThan sp. lessThan i greaterThan Artemia lessThan /i greaterThan gut isolates, when introduced in to the gut of adult lessThan i greaterThan Artemia lessThan /i greaterThan along with pathogenic bacteria, they multiplied and colonized faster and seen in higher number than the pathogenic bacteria . During the present study it was found that lessThan i greaterThan Acetobacterium lessThan /i greaterThan sp. effectively controlled the growth of lessThan i greaterThan V. harveyi lessThan /i greaterThan and lessThan i greaterThan Alteromonas lessThan /i greaterThan sp. than lessThan i greaterThan Aeromonas lessThan /i greaterThan sp. Hence this study adds more towards the use of gut isolates of lessThan i greaterThan Artemia lessThan /i greaterThan as probiotics and on controlling the bacterial pathogens in an aquaculture system to solve the bacterial Pathogenicity.
