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 ... -

Raghukumar, C.; Pathak, S.C.; Chandramohan, D. (New Delhi: Oxford & IBH, 1988) -
Candidates for the development of consortia capable of petroleum hydrocarbon degradation in marine environment
David, J.; Gupta, R.; Mohandass, C.; Nair, S.; LokaBharathi, P.A.; Chandramohan, D. (Fostering International Coop. Res., UK, 1995)Bacteria and yeasts from different niches of the tropical Indian waters were screened for their hydrocarbon degrading potential using 1% w/v in artificial seawater over a period of 6 days. About 20% of the 75 bacterial and ... -
Changes in the marine green alga @iChaetomorpha media@@ on infection by a fungal pathogen
Raghukumar, C.; Chandramohan, D. (Walter de Gruyter, Berlin, 1988)Biochemical changes in the green filamentous alga @iChaetomorpha media@@ Kutzing infected with a holocarpic endobiotic fungus@@ Pontisma lagenidioides@@ Petersen were studied. Healthy plants of @iC. media@@ were inoculated ... -
Characterization of purple and green photosynthetic bacteria isolated from the lagoon of Agatti Atoll (Lakshadweep Sea)
LokaBharathi, P.A.; Chandramohan, D. (Indian Academy of Sciences, 1986)The occurrence and characterisation of photosynthetic sulphur bacteria in the tropical waters is reported. These were found with decaying beds of seagrass at Agatti Island, Lakshadweep, India. These were cultured and ... -
Coastal microbial processes

Computer aided taxonomy (CAT): Approach for understanding systematics of marine biota
Chavan, V.S.; Kavlekar, D.P.; Chandramohan, D. (NISCAIR, CSIR, 1998)Computer aided taconomy (CAT) is gaining importance day by day. In order to familiarise the taxonomy and its continuing usage an attempt has made to develop a module for knowing the systematics of organisms and to generate ... -
Computerizing marine biota: a rational approach
Chavan, V.S.; Chandramohan, D.; Parulekar, A.H. (1991)Data on marine biota while being extensive are also patchy and scattered; thus making retrieval and dissemination of information time consuming. This emphasise the need for computerizing information on marine biota with ... -
Contribution of the thraustochytrid Corallochytrium limacisporum Raghu-kumar to microbial biomass in coral reef lagoons
Raghukumar, S.; Chandramohan, D.; Ramaiah, N. (CSIR-NISCAIR, 1987)ATP and organic carbon (OC) contents of cells of 5 isolates of thraustochytrids, including one of Corallochytrium limacisporum were estimated from cultures OC:ATP ratio in these isolates averaged 99 Based on these and the ... -
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, ... -
Culturable heterotrophic bacteria from the euphotic zone of the Indian Ocean ocean during the summer monsoon
Nair, S.; LokaBharathi, P.A.; Chandramohan, D. (Elsevier, 1994)Cuturable heterotrophic bacterial counts (viable counts: VC) by surface plating on ZoBell medium and total bacterial counts (TC) by epifuorenscence microscopy were carried out in sea water off the southwest coast of India ... -
Data bases in life sciences and biotechnology: A directory
Chavan, V.S.; Mohan, T.M.; Chandramohan, D.; Arora, J.R.; Parulekar, A.H (National Inst of Oceanography, Goa, 1995) -
Databases in Indian biology: The state of the art and prospects
Chavan, V.S.; Chandramohan, D. (Current Science Association, Bangalore, India, 1995)Only 0.85% of the scanned 7500 database titles are related to biology and biotechnology developed in India. Of these, 73% are either bibliographic or directory type and the rest are textural, numeric or multimedia in nature. ... -
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 ... -

Densities, cellulases, alginate and pectin lyases of luminous and other heterotrophic bacteria associated with marine algae
Ramaiah, N.; Chandramohan, D. (Elsevier, 1992)Epiphytic luminous and non-luminous bacteria were determined quantitatively for eight intertidal algal species from rocky beaches of Goa and Lakshadweep coral reef lagoon. Luminous bacteria were present on all eight algal ... -
Differential sensitivity of pigmented and non-pigmented marine bacteria to metals and antibiotics
Nair, S.; Chandramohan, D.; LokaBharathi, P.A. (Pergamon, 1992)The response of pigmented and non-pigmented marine bacteria to metals and antibiotics was investigated. The two groups responded differently to heavy metals and antibiotics. Pigmented bacteria were more resistant to metals. ... -
