(Springer, 2012)A rapid two-step technique for bioremediation of the anthraquinone dye, the Reactive Blue 4 (RB4) by a marine-derived fungus is reported here. In the first step, 1,000 mg l sup(−1) of this dye treated with partially purified ... -
A report on the occurrence of Thraustochytrid species in Indian waters
Raghukumar, S.; Raghukumar, C. (Mycological Society of India, 1988)Thraustochytrids were isolated from 52 samples of 14 substrata from the coastal waters of Goa, Tamil Nadu and Lakshadweep islands and the Arabian Sea. A total of 9 species are reported in this paper. These are: Corallochytrium ... -
A review on deep-sea fungi: Occurrence, diversity and adaptions
Raghukumar, C.; Damare, S.R.; Singh, P. (Walter de Gruyter, 2010)The few studies on deep-sea fungi in recent years (using either culturing or molecular signatures) have provided evidence on their occurrence. A majority of culture-dependent and culture-independent fungi recovered have ... -
A thermostable metal-tolerant laccase with bioremediation potential from a marine-derived fungus
DeSouza-Ticlo, D.; Sharma, D.; Raghukumar, C. (Springer, 2009)Laccase, an oxidoreductive enzyme, is important in bioremediation. Although marine fungi are potential sources of enzymes for industrial applications, they have been inadequately explored. The fungus MTCC 5159, isolated ... -
Abundance of Thraustochytrid fungi in the Arabian Sea

Algal-fungal interactions in the marine ecosystem: Symbiosis to parasitism
Raghukumar, C. (CSMCRI, India, 2006)A wide array of partnership exists between algae and fungi. These range from loose commensal association between algae and fungi as in primitive lichens, obligate symbiotic association termed mycophycobioses between the ... -
Anaerobic denitrification in fungi from the coastal marine sediments off Goa, India
Manohar, C.S.; Raghukumar, C. (Elsevier, 2009)Denitrification is a microbial process during which nitrate or nitrite is reduced under anaerobic condition to gaseous nitrogen. The Arabian Sea contains one of the major pelagic denitrification zones and in addition to ... -
Assemblage of benthic diatoms and culturable heterotrophs in shallow-water hydrothermal vent of the D. Joao de Castro Seamount, Azores in the Atlantic Ocean
Raghukumar, C.; Mohandass, C.; Cardigos, F.; DeCosta, P.M.; Santos, R.S.; Colaco, A. (Current Science Association, India, 2008)The shallow-water hydrothermal vent of D. Joao de Castro Seamount in the North Atlantic, between the Azorean islands Sao Miguel and Terceira, is characterized by yellow and white zones which are distinct in physical and ... -
Assessment of fungal diversity in deep-sea sediments by multiple primer approach
Singh, P.; Raghukumar, C.; Verma, P.; Shouche, Y. (Springer, 2012)Increasing evidence of the fungal diversity in deep-sea sediments has come from amplification of environmental DNA with fungal specific or eukaryote primer sets. In order to assess the fungal diversity in deep-sea sediments ... -
Association of thraustochytrids and fungi with living marine algae
Raghukumar, C.; Nagarkar, S.; Raghukumar, S. (Cambridge Univ Press, 1992)Occurrence of thraustochytrids, yeasts and mycelial fungi in six marine algae was studied. Thraustochytrids and mycelial fungi were recovered from non-surface-sterilized as well as surface-sterilized pieces of algae, whereas ... -
Bacterial abundance, communities and heterotrophic activities in the coastal waters off Tamil Nadu
Ramaiah, N.; Raghukumar, C.; Sheelu, G.; Chandramohan, D. (NISCAIR, CSIR, 1996)Culturable aerobic heterotrophic bacterial (CAHB) numbers, total direct counts (TDC), bacterial generic composition and uptake of labelled glucose by natural microbial assemblages were studied from a few selected coastal ... -
