title: Interspecific Interactions Among Members of Family Halobacteriaceae from Natural Solar Salterns.
abstract: Solar salterns are crystallizer ponds with highly diverse extremophilic microbial flora living individually or in consortium. Twenty-four culturable haloarchaeal isolates were obtained from solar salterns of Goa, which were grouped under Halococcus, Haloferax, Haloarcula and Halorubrum. Cell-free supernatants of different isolates were checked against each other by pour plate technique combined with agar well diffusion method. This resulted in a zone of growth inhibition or stimulation around wells, indicating that some isolates had antagonistic and/or a beneficial effect on the other genera. Thus, members of family Halobacteriaceae were found to secrete extracellular metabolites, which can act as growth enhancers or repressors.
