Endolithic fungi from deep sea calcareous substrata: isolation and laboratory studies
Raghukumar, C.; Raghukumar, S.; Sharma, S.; Chandramohan, D. (Oxford and IBH, New Delhi, 1992)Fungi were isolated from calcareous animal shells at 100-860 m depth in the Bay of Bengal. All the species isolated were terrestrial ones, Aspergillus restrictus Smith being the most common. The behaviour of this fungus ... -
Endolithic marine cyanobacteria
Raghukumar, C. (Tiruchirapalli: National Facility of Marine Cyanobacteria, 1993) -
Enhanced production of laccase by a marine fungus during treatment of colored effluents and synthetic dyes
DeSouza-Ticlo, D.; Tiwari, R.; Sah, A.K.; Raghukumar, C. (Elsevier, 2006)Paper and pulp mills, textile and dye-making industries and alcohol distilleries release highly colored effluents that are relatively difficult to decolorize by chemical and physical treatments. White-rot basidiomycetous ... -
Extremophilic microbes: Diversity and perspectives
Satyanarayana, T.; Raghukumar, C.; Shivaji, S. (Indian Academy of Sciences, 2005)A variety of microbes inhabit extreme environments. Extreme is a relative term, which is viewed compared to what is normal for human beings. Extreme envi-ronments include high temperature, pH, pressure, salt concentration, ... -
Four marine-derived fungi for bioremediation of raw textile mill effluents
Verma, A.K.; Raghukumar, C.; Verma, P.; Shouche, Y.S.; Naik, C.G. (Elsevier, 2010)Textile dye effluents pose environmental hazards because of color and toxicity. Bioremediation of these has been widely attempted. However, their widely differing characteristics and high salt contents have required ... -
Fungal community analysis in the deep-sea sediments of the central Indian Basin by culture-independent approach
Singh, P.; Raghukumar, C.; Verma, P.; Shouche, Y. (Springer, 2011)Few studies have addressed the occurrence of fungi in deep-sea sediments, characterized by elevated hydrostatic pressure, low temperature, and fluctuating nutrient conditions. The diversity of fungi at three locations of ... -
Fungal diversity from various marine habitats deduced through culture-independent studies
Manohar, C.S.; Raghukumar, C. (Blackwell, 2013)Studies on the molecular diversity of the micro-eukaryotic community have shown that fungi occupy a central position in a large number of marine habitats. Environmental surveys using molecular tools have shown the presence ... -
Fungal diversity in deep-sea sediments revealed by culture-dependent and culture-independent approaches
Singh, P.; Raghukumar, C.; Meena, R.M.; Verma, P.; Shouche, Y. (Elsevier, 2012)Diversity of fungi from deep biosphere is recently gaining an increasing attention. We investigated fungal diversity in two sediment cores approx. 40 cmbsf (cm below seafloor) at a depth of approx. 5000 m in the Central ... -
Fungal diversity in oxygen-depleted regions of the Arabian Sea revealed by targeted environmental sequencing combined with cultivation
Manohar, C.S.; Raghukumar, C.; Behnke, A.; Stoeck, T. (Blackwell Publishing, 2010)In order to study fungal diversity in oxygen minimum zones of the Arabian Sea, we analyzed 1440 cloned small subunit rRNA gene (18S rRNA gene) sequences obtained from environmental samples using three different PCR primer ... -
Fungal invasion of massive corals
Raghukumar, C.; Raghukumar, S. (Blackwell, 1991)Five species of corals from the Andaman Islands in the Bay of Bengal (Indian Ocean) have been regularly found to have single or multiple necrotic patches. The occurrence of such corals with necrotic patches varied from ... -

Fungal parasites of the marine green algae, Cladophora and Rhizoclonium
Raghukumar, C. (Walter de Gruyter, Berlin, 1986)Diseases caused by three fungal parasites in the green algal genus @iCladophora@@ from the beaches of Goa and Lakshadweep islands in Arabian sea in India are described. These are caused by @iSirolpidium bryopsidis, Olpidium ... -
Fungi and macroaggregation in deep-sea sediments
Damare, S.R.; Raghukumar, C. (Springer, 2008)Whereas fungi in terrestrial soils have been well studied, little is known of them in deep-sea sediments. Recent studies have demonstrated the presence of fungal hyphae in such sediments but in low abundance. We present ... -
Fungi and their role in corals and coral reef ecosystems
Raghukumar, C.; Ravindran, J. (Springer, 2012)Fungi in coral reefs exist as endoliths where they penetrate carbonate structures, endobionts where they are associated with living organisms such as corals, sponges and holothurians, as saprotrophs in the coral mucus, ... -
Fungi from marine habitats: Application in bioremediation
Raghukumar, C. (Elsevier, 2000)This paper synthesizes the work done on decolourization of bleach plant effluent and synthetic dyes using fungi from marine habitats. Three fungi obtained from marine habitats removed up to 60-95% of Kraft paper mill bleach ... -
Fungi in deep-sea sediments of the Central Indian Basin
Damare, S.R.; Raghukumar, C.; Raghukumar, S. (Elsevier, 2006)Although a great amount of information is available on bacteria inhabiting deep-sea sediments, the occurrence of fungi in this environment has been poorly studied and documented. We report here the occurrence of fungi in ... -
Fungi in Porites lutea: Association with healthy and diseased corals
Ravindran, J.; Raghukumar, C.; Raghukumar, S. (Inter-Research, 2001)Healthy and diseased scleractinian corals have been reported to harbour fungi. However, the species of fungi occurring in them and their prevalence in terms of biomass have not been determined and their role in coral ... -
Fungi living in diverse extreme habitats of the marine environment
Raghukumar, S.; Raghukumar, C.; Manohar, C.S. (Mycological Society of India, 2014)The marine environment contains several habitats characterized by extreme living conditions. However, extremophilic marine fungi were neither well known, nor often studied. Many studies in recent years have shown that fungi ... -
