Halophiles are extremophiles living in extreme salt environments and are a huge untapped resource of potential industrially important metabolic products with interesting industrial applications. My PhD work aimed at exploring the halophiles from solar salterns of Goa and Tamil Nadu, India and screening them for the synthesis of Polyhydroxyalkanoates (PHAs) and studying their mechanism to combat such hypersline environment. Potential biopolymer producing isolates were identified as Bacillus megaterium nd Halogeometricum borinquense. The polymer accumulated was characterized to be a homopolymer of PHB and co-polymer of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(HB-co-HV)]. High production costs, and low yields are the major hurdles for the commercial production and application of PHA. Our study, reported the potential of Hgm. borinquense strain E3 to synthesize copolymer of [P(HB-co-HV)] naturally, unlike most of the bacteria which require media supplements such as propionic/valeric acid which are expensive & toxic as precursors for PHBV synthesis. Moreover, industrial processes require organisms with standing harsh physicochemical conditions like high salt concentration analogous to high ionic strength and low water activity (aw) and employing extreme halophiles can efficiently withstand and grow at such extreme conditions.

M.Sc. Project title: “Microbiological Study of Ground and other Waters in Margao-Ward-No-1 Housing Sonsoddo-Garbage Dump of Municipality of Margao-Goa-India.”.
Margao is the commercial capital of Goa-India. The waste from the city is dumped at the rate of 40-50 tonnes/day, at an elevated site namely, Sonsoddo in Gogol ward No.1 under Margao municipality. The site at the time of our study in 2008 was a huge man made hillock of mixed garbage. Ground and other water samples (bore well, tube well, drainage, etc.) were examined for physical parameters and microbiological analysis. My study reported heavy bacterial contamination in ground water of active wells around the Sonsoddo garbage dump conventionally known to be hazardous to human health. Significantly the study was expected to bring public awareness, guide local authorities in framing appropriate management measures that would protect the well waters, reduce pollution and disinfect the ground water for safe use.
