  • Transformation of alpha-santonin by Pseudomonas cichorii S. Identification of products 
    Naik, U.P.; Mavinkurve, S.; Naik, U.S.; Paknikar, S.K. (Indian Journal of Chemistry. 27B; 1988; 381-282.)
    4alpha, 5alpha-Dihydroxysantonin (4) and ethyl 3-oxoeudesma-4, 6- diene-12-oate (2, 4-DNP derivative 3) have been characterised as microbial transformation products of alpha-santonin (1) by Pseudomonas cichorii S. The ...
  • Isolation of potential ligninolytic organisms 
    Nazareth, S.W.; Mavinkurve, S. (International Biodeterioration. 23(5); 1987; 271-180.)
    Organisms were isolated from soil, bark, ret liquor and other sources by enrichment on Klason lignin or guaiacol. The isolates were screened for their ability to assimilate various phenolic compounds, including methoxylated ...
  • Laboratory studies on retting of coconut husk 
    Nazareth, S.W.; Mavinkurve, S. (International Biodeterioration. 23(6); 1987; 343-355.)
    Laboratory rets set by soaking the coconut husk in water were monitored by physico-chemical analysis of leachate and husk. Increasing amounts of pectins and phenols were leached in ret liquor during a period of 9 days of ...
  • Alpha-santonin 1,2-reductase and its role in the formation of dihydrosantonin and lumisantonin by Pseudomonas cichorii S 
    Naik, U.P.; Mavinkurve, S. (Canadian Journal of Microbiology. 33(8); 1987; 658-662.)
    1,2-Dihydrosantonin is the first stable product in the degradative pathway of alpha-santonin byPseudomonas cichorii S. Its formation is catalyzed by an oxidoreductase, which is NADH or NADPH dependent and has an apparent ...
  • Mechanism of uptake of alpha-santonin by Pseudomonas cichorii strain S 
    Furtado, I.; Sangodkar, U.M.X.; Mavinkurve, S. (Biotechnology and Bioengineering. 30; 1987; 991-994.)
    Uptake of various solid hydrophobic substances is reported to occur by their solubilization, mediated by the cells through secretion of extracellular factors, or via direct contact of cells with the substrate. Pseudomonas ...
  • Characterization of cellulolytic enzyme component from Aspergillus terreus and its mutant 
    Araujo, A.; D'Souza, J. (Journal of Fermentation Technology. 64(5); 1986; 463-467.)
    Cellulases produced by Aspergillus terreus ATCC 52430 and its mutant, UNGI-40,were resolved into four components, one beta-glucosidase , an exoglucanase, and two endoglucanases (Endo I and II) by gel filtration and ...
  • Degradation of ferulic acid via 4-vinylguaiacol by Fusarium solani (Mart.) Sacc 
    Nazareth, S.W.; Mavinkurve, S. (Canadian Journal of Microbiology. 32(6); 1986; 494-497.)
    Fusarium solani (Mart.) Sacc. metabolizes ferulic acid to a transient intermediate, 4-vinylguaiacol, a compound hitherto not reported in the metabolic pathway of ferulic acid in fungi. The compound was isolated in pure ...
  • Enzymatic saccharification of rice straw and biomass production 
    Araujo, A.; D'Souza, J. (Biotechnology and Bioengineering. 28(10); 1986; 1503-1509.)
    A comparative study on the saccharification of pretreated rice straw was brought about by using cellulase enzyme produced by Aspergillus terreus ATCC 52430 and its mutant strain UNGI-40. The effect of enzyme and substrate ...
