Antimicrobial Potentials of Phospholipid Compound Produced By Halophilic Bacillus subtilis isolated from Alkaline Meteorite Crater Lonar Lake, India

Hypersaline environments are widely distributed on the earth s continent where they exist either as natural water bodies such as permanent saline lakes, ephemeral saltpans and salt marshes,or as artificial solar salterns (Litchfield and Gillevet; 2002). The microbial diversity of saline lakes has been studied primarily by focusing on the isolation and characterization of individual organisms with potential industrial application (Horikoshi K., 1999; Jones et al, 1998). Microorganisms that thrive in these environments have been broadly classified into halophilic microorganism (that is, require salt for their viability) and halotolerant microorganisms which are able to grow in the absence as well as in the presence of NaCl. Halophiles can be further divided into slight halophiles that grow optimally in 3% (w/v) total salt, moderate halophiles optimal growth at 315% (w/v) salt and extreme halophiles that grow optimally at 25% (w/v) salt (Ventosa et al, 1998). The domain bacteria typically contains many types of halophilic and halotolerant microorganisms that spread over a large number of phylogenetic subgroups. Most of these are moderate rather than extreme halophiles (Oren, 2002).
