A rapid two-step bioremediation of the anthraquinone dye, Reactive Blue 4 by a marine-derived fungus
(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 study of the carbon dioxide system in the northern Indian Ocean during premonsoon
(Elsevier, 1994)Extensive data sets on the carbon dioxide system in the northern Indian Ocean have been obtained during the premonsoon season. A marked increase (~50 ~kM) in the total carbon dioxide (TCO@d2@@) content is observedin deep ... -
Bifunctional xylanases and their potential use in biotechnology
(Society for Industrial Microbiology, 2008)Plant cell walls are comprised of cellulose, hemicellulose and other polymers that are intertwined. This complex structure acts as a barrier to degradation by single enzyme. Thus, a cocktail consisting of bi and multifunctional ... -
Boron in seawater of Wadge bank region in the Indian Ocean
(CSIR-NISCAIR, 1984)In the upper 200 m in the Wadge Bank region B varies from 3.09 to 4.95 mg.kg/1. B/Cl ratio ranges from 0.159 to 0.256. Depthwise distribution of B shows its inverse relationship with dissolved oxygen, direct relationship ... -
Carbohydrate-degrading bacteria closely associated with Tetraselmis indica: Influence on algal growth
(Inter-Research, 2012)The interactions between the algal species Tetraselmis indica and strains of bacteria are examined. Three bacterial strains were isolated and sequence analysis of the 16S rDNA indicated that the organisms belong to the ... -
Comment on 'degradation of polychlorinated dibenzo-p-dioxin and dibenzofuran contaminants in 2,4,5-T by photoassisted iron-catalyzed hydrogen peroxide by J.J. Pignatello and L.Q. Huang, Wat. Res. 27, 1731-1736 (1993)'
(Elsevier, 1994)A doubt has been raised on the use of a salts as catalyst for the degradation process. The impact of H@d2@@ O@d2@@ on degradation of PCDD and PCDF is not well defined. The observed variation in the concentration of the ... -
Conversion Efficiency in the Shrimp, Metapenaeus Monoceros (Fabricius), Fed on Decomposed Mangrove Leaves
(CSIR-NISCAIR, 1980)Feeding experiments were carried out with Metapenaeus monoceros using mangrove leaves at different stages of decomposition, in combination with rice bran. Maximum conversion efficiency was found in shrimps fed completely ... -
Corrosion and microfouling of copper and its alloys in a tropical marine waters of India (Mangalore)
(NISCAIR, CSIR, 1995)Rate of corrosion, extent and nature of microfouling of copper, cupronickel 70/30 and cupronickel 90/10 have been studied for three different seasons at a station on the west coast of India. The corrosion rates for all the ... -
Crude oil degradation by phosphate-solubilizing bacteria
(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, ... -
Decolorization of molasses spent wash by the white-rot fungus Flavodon flavus, isolated from a marine habitat
(Springer, 2001)Flavodon flavus (Klotzsch) Ryvarden, a basidiomycete (NIOCC strain 312) isolated from decomposing leaves of a sea grass, decolorized pigments in molasses spent wash (MSW) by 80% after 8 days of incubation, when used at ... -
Degradation of barnacle nauplii: Implications to chitin regulation in the marine environment
(Springer, 2013)The exoskeleton of most invertebrate larval forms is made of chitin, which is a linear polysaccharide of beta (1→4)-linked N-acetylglucosamine (GlcNAc) residues. These larval forms offer extensive body surface for bacterial ... -
Experimental studies on Urea Degradation in Seawater
(Indian Association for Limnology and Oceanography, 1980)The rate of urea degradation in seawater was studied under various conditions and the kinetics of urea degradation was evaluated. Urea decomposition experiments showed that the rates and quantity of ammonium oxidation were ... -
Further studies in using mangrove foliage as a prawn feed
(Indian Association for Limnology and Oceanography, 1983)Changes in biochemical composition and energy content of foliage of eight mangrove species at various phases of life and during decay were studied. Decomposition resulted in loss of organic contents, carbon and C:N ratio ... -
Hydrochemistry of the Bay of Bengal: Possible reasons for a different water-column cycling of carbon and nitrogen from the Arabian Sea
(Elsevier, 1994)A study on biogeochemical cycling in the western Bay of Bengal was undertaken during two seasons (pre-southwest monsoon and northeast monsoon of 1991). Relationships of the conservative tracers NO and PO with potential ... -
Litter fall and energy flux in a mangrove ecosystem
(Academic Press, 1997)Production, elemental composition and In situ decomposition of litter of Rhizophora apiculata, R. mucronata, Sonneratia alba and Avicennia offcinalis were studied in a mangrove ecosystem fringing Mandovi-Zuari Estuaries ... -
Marine pollution - What are we heading for?
(Indian National Science Academy, New Delhi (India), 1999)Unlike the open ocean, the coastal zone is the most affected and vulnerable to human abuse with several nearshore areas including well-flushed regions and enclosed and semi-enclosed seas getting increasingly polluted. This ... -
Respiration rates in subsurface waters of the northern Indian Ocean: Evidence for low decomposition rates of organic matter within the water column in the Bay of Bengal
(Pergamon, 1996)Depth profiles of activity of the respirtory Electron Transport System (ETS) have been generated at several locations in the northern Indian Ocean. The results reveal much lower ETS activities in subsurface waters of the ... -
