Behaviour of marine oil-degrading bacterial populations in a continuous culture system
Mohandass, C.; David, J.J.; Nair, S.; LokaBharathi, P.A.; Chandramohan, D. (Springer, 1997)In pursuit of developing an oil-degrading microbial consortium, we used the principle of "plasmid assisted molecular breeding" (PAMB) in a continuous culture system. Three marine bacteria, Pseudomonas putida, Brevibacterium ... -
Crude oil degradation by phosphate-solubilizing bacteria
DeSouza, M.J.B.D.; Nair, S.; David, J.J.; Chandramohan, D. (Springer, 1996)Phosphate-solubilizing bacteria were isolated from tropical areas around the Indian peninsula. Two of the isolates showed high phosphatase activity. The isolates were identified as Klebsiella pneumoniae and Bacillus pumilus, ... -
Degradation of crude oil by marine cyanobacteria
Raghukumar, C.; Vipparty, V.; David, J.J.; Chandramohan, D. (Springer, 2001)The marine cyanobacteria Oscillatoria salina Biswas, Plectonema terebrans Bornet et Flanhault and Aphanocapsa sp. degraded Bombay High crude oil when grown in artificial seawater nutrients as well as in plain natural ... -
Nitrification in reef corals
Wafar, M.V.M.; Wafar, S.; David, J.J. (American Society of Limnology and Oceanography, 1990)N-Serve blockage of NH4+ oxidation showed that nitrification in reef corals is quantitatively important. Average NO3- production was 9.4+-6.0 nmol (mg coral tissue N)-1 h-1 (mean +- 1 SE; n = 12), equivalent to 17% of the ... -
Thraustochytrid protists degrade hydrocarbons
Raikar, M.T.; Raghukumar, S.; Vani, V.; David, J.J.; Chandramohan, D. (NISCAIR, CSIR, 2001)Although thraustochytrid protists are known to be of widespread occurrence in the sea, their hydrocarbon-degrading abilities have never been investigated. We isolated thraustochytrids from coastal waters and sediments of ...
