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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Microbiological transformation of alpha-santonin to 11-demethyl-eudesm-4-ene-3,6-dione

Furtado, I.; Mavinkurve, S.; Paknikar, S.K. (Letters in Applied Microbiology. 6(2); 1988; 27-30.)

Pseudomonas strain S (ATCC 43388) formed a crystalline transformation product of alpha-santonin. Based on the spectroscopic characteristics, the product has been identified as 11-demethyl-eudesm-4-ene-3,6-dione.
Response of Plant Species to the Mining Reject

Veeresh, A.V.
Water-borne Hyphomycetes found in Ethiopia

Bhat, D.J.; Chien, C.Y. (Transactions of the Mycological Society of Japan. 31; 1990; 147-157.)
Studies in Three Canavalia Species

Rodrigues, B.F.
Upstream regulatory sequence for transcriptional activator XylR in the first operon of xylene metabolism on the TOL plasmid

Inouye, S.; Gomada, M.; Sangodkar, U.M.X.; Nakazawa, A.; Nakazawa, T. (Journal of Molecular Biology. 216(2); 1990; 251-260.)

Transcription of the first operon coding for m-xylene-degrading enzymes on the TOL plasmid of Pseudomonas putida is activated by the xylR gene product in the presence of m-xylene. The operon has the consensus sequence of ...
Reclamation and Rehabilitation of Iron Ore Mine Wastes

Coelho, F.L.
Changing ecology of Goa's coastline due to human disturbances - Causes and control measures

Rodrigues, B.F. (Indian Journal of Environmental Protection. 11(6); 1991; 425-427.)
Identification of genes specifying proline biosynthesis In marine bacterium Alteromonas haloplanktis

Sangodkar, U.M.X. (Biotechnology Letters. 13(11); 1991; 839-843.)

A gene bank of total DNA of a marine bacterium, Alteromonas haloplanktis, was constructed on pBR322. Two hybrid plasmids pUS2010 and pUS2011 carrying inserts of 8.2 and 5.7 kb, respectively, were isolated that complemented ...
Glucose influenced degradation of alpha-santonin in pseudomonas sp. strain S (ATCC 43388)

Sangodkar, U.M.X.; Mavinkurve, S. (Acta Biotechnologica. 11(1); 1991; 67-71.)

Pseudomonas sp., strain S ATCC 43 388 utilizes alpha-santonin by inducible enzyme system measurable by oxygen uptake. Cells grown on acetate or benzoate show negligible oxygen consumption with alpha-santonin. However, ...
Characteristics of starch grains in three Canavalia species

Rodrigues, B.F.; Torne, S.G. (Agricultural and Biological Research. 7(2); 1991; 142-144.)

The purpose of the present investigation is to isolate the starch from three Canavalia species and to study the starch grains with respect to morphology, dimensions, gelatiiiizations, temperature and Iodine absorption spectra.
