Item Association of Enterobacter with Coconut Root (Wilt) Disease(1976-09) Mathew George; Potty, V.P.; Jayasankar, N.P.Item A bacterial blight disease of cardamom(2007-02-08) Mathew George; Thomas Joseph; Potty, V.P.; Jayasankar, N.P.Item A colorimetric method for the estimation of Pyrogallol(2007-02-08) Joseph, K.V.; Potty, V.P.; Jayasankar, N.P.Pyrogallol in the 5-20 jug range has been estimated colorimetrically in acetic acid after treatment with paradimethyl amino benzaldehyde and sulphuiic acid. Some factors affecting the formation of colour have been studied.Item Effect of crop mixing on the coconut Rhizosphere(2007-02-08) Potty, V.P.; Mathew George; Jayasankar, N.P.Item Increase in Polyphenol Oxidase and Peroxidase with Higher Intensities of Coconut Root (Wilt) Disease(1976-06) Joseph, K.V.; Potty, V.P.; Jayasankar, N.P.The levels of polyphenol oxidase and peroxidase were found to increase with intensity of coconut root (wilt) disease. The correlation between phenol oxidising enzymes and coconut root (wilt) index formulated on the basis of foliar symptoms was positive.Item Influence of crop mixing of hybrid napier on the root zone microflora of the coconut palm(1) Potty, V.P.; Jayasankar, N.P.Item Microbial Degradation of Coconut Waste Materials(2007-02) Potty, V.P.; Joseph, K.V.; Mathew George; Jayasankar, N.P.Retting of coconut husk yields coir fibre and coconut pith both of which are resistant to microbial attack. The former finds a place in commerce, while the disposal of the latter is a problem. Enrichment culture methodology using lignocellulose as source of carbon yielded a fungus identified as Poria ravanulae. The fungus could utilise coconut pith which is essentially a ligno cellulose complex, as source of carbon for its growth. The coconut P. ravanulae isolates were lignoclastic, its polyphenol oxidase was noninducible and could use a range of phenolic substrates for growth. Replacement culture techniques indicated the conversion of trihydric phloroglucinol to dihydric resorcinol.Item Processing and fermentation of coconut toddy(1978) Potty, V.P.; Joseph, K.V.; Sethumadhava Menon, K.; Jayasankar, N.P.Item Rapid detection of indole compounds with ehrlich's reagent(1978-01) Potty, V.P.; Joseph, K.V.; Jayasankar, N.P.
