    Uptake hydrogenase in Rhizobium and nodule leghemoglobin in cow pea miscellany hosts (1982)
    Springer
    Archives of microbiology 133 (1982), S. 303-306 
    Details
    ISSN: 1432-072X
    Keywords: Uptake hydrogenase ; Leghemoglobin (Lb) ; Nitrogenase ; Cow pea miscellany hosts ; Hup+ and Hup- Rhizobium strains

    Topics: Biology
    Notes: Abstract Two effective strains of green gram rhizobia S24 (slow growing and Hup+) and M11 (fast growing and Hup-) were tested for leghemoglobin production in nodules and effectivity on six species of ‘cow pea miscellany hosts’. Both strains nodulate green gram [Vigna radiata (L.) (Wilczek)], black gram [Vigna mungo (L.) (Hepper)], cow pea [Vigna unguiqulata (L.)], moth bean [Vigna aconitifolia (Jacq.) (Marechel)], Cluster bean [Cyamopsis tetragonoloba (L.) (Taub.)] and pigeon pea [Cajanus cajan (L.)]. In all these hosts, nodules formed by strain M11 contained 1.5 to 2 times more leghemoglobin than the nodules formed by strain S24. Gel electrophoresis of nodule contents of different host species showed a high concentration of a fast-moving ferricoxy leghemoglobin in the nodules of plants inoculated with strain M11 as compared to that of strain S24. Strain M11, however, was relatively less effective than strain S24 on black gram, cow pea and moth bean and was at par with the later on green gram, cluster bean and pigeon pea. Hydrogen recycling ability of the strain S24 was observed in nodules of all the host species. The effective functioning of strain S24 at low levels of leghemoglobin suggests an involvement of recycling hydrogenase in maintaining an appropriate oxidation-reduction potential in nodules.

    Description / Table of Contents: Résumé Par criblage de sept levures de distillerie, nous avons identifié deux souches deSaccharomyces cerevisiae produisant de l'éthanol, l'une rapidement et l'autre lentement. Les niveaux des quatre enzymes-clés, invertase, pyruvique décarboxylase (PDC), alcool déshydrogénase (ADH) et aldéhyde déshydrogénase (ADD) ont été déterminés chez ces souches pendant la production fermentative d'éthanol en batch. Chez les deux souches, les niveaux enzymatiques varient au cours de la fermentation. A tous les stades de celle-ci, la souche rapide présente un niveau élevé de PDC et ADH, et un niveau d'ADD inférieur à celui de la souche lente.
    Abstract: Resumen Al hacer un muestreo siete levaduras de cerveza se han identificado dos cepas deSaccharomyces cerevisiae, caracterizandolas como productoras lenta y rápida de etanol. Para ambas cepas se determinaron, en el periodo de crecimiento exponencial los niveles de cuatro enzimas clave: invertasa, piruvato decarboxilasa (PDC), alcohol deshidrogenas (ADH) y aldehido deshidrogenasa (ADD). Los niveles de estos enzimas variaron durante la fermentación en las dos cepas. Los niveles de PDC y de ADH fueron más bajos y el nivel de ADD más bajo en la cepa fermentadora rápida comparada con la cepa fermentadora lenta.
    Notes: Summary By screening seven distillers' yeast strains, two strains ofSaccharomyces cerevisiae were identified as being either slow or fast ethanol producers. The levels of four key enzymes, invertase, pyruvate decarboxylase (PDC), alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ADD) in these strains during batch-fermentative production of ethanol were determined. In both strains, the levels of these enzymes varied during the fermentation. The fast-fermenting strain had higher levels of PDC and ADH, and lower levels of ADD, as compared to the slow-fermenting strain, at all stages of fermentation.

    Synthesis of xylanase byTrichoderma reesei (1986)

    Description / Table of Contents: Résumé Une xylanase est synthétisée parTrichoderma reesei lorsque cet organisme est cultivé en présence de xylane, de cellulose ou de phospho-cellulose. Le xylane est le meilleur inducteur. D'autres enzymes cellulolytiques, notamment une endo-glucanase et une FP-ase, sont synthétisées en faibles quantités, mais le niveau en β-glucosidase est trés élevé. Des mutants ayant des niveaux d'enzymes cellulolytiques modifiés présentent un niveau de xylanase inchangé, ce qui suggère que cette enzyme est contrôlée de façon indépendante.
    Abstract: Resumen Trichoderma reesei sintetiza xilanasa cuando se hace crecer en presencia de xilano, celulosa o fosfocelulosa. El xilano es el mejor inductor de xilanosa. Tambien se producen otros enzimas celulolíticos en pequeñas cantidades como endoglucanasa y FPasa aunque la producción de β-glucosidasa puede alcanzar niveles elevados. Mutantes con niveles de enzimas celulolíticos alterados no mostraron ninguna modificación en los niveles de xilanasa sugiriéndose pues un control independiente de dicho enzima en este organismo.
    Notes: Summary Xylanase is synthesized byTrichoderma reesei when grown in the presence of xylan, cellulose or phosphocellulose. Xylan is the best inducer of xylanase. Other cellulolytic enzymes such as endoglucanase and FPase are synthesized in small quantities, but the level of β-glucosidase is very high. Mutants with altered levels of cellulolytic enzymes showed an unaltered level of xylanase, suggesting its independent control in this organism.

    Selective induction of β-glucosidase in Trichoderma reesei by xylan (1982)
    Springer

    Notes: Summary In Trichoderma reesei, QM 9414, β-glucosidase can be selectively induced by xylan. At a concentration of 0.5% xylan in the growth medium, the yield of β-glucosidase is 3 times more than in cellulose medium suggesting that the synthesis of this enzyme in this organism is under an independent regulatory control.

    Notes: Summary Bajra (Pennisatum americanum) — a millet crop grown in the semi-arid, subtropical region of India, was surveyed for associative nitrogen-fixing bacteria in roots. Out of 20 root samples collected from 10 locations, 15 showed a high population ofPseudomonas azotogensis. The bacterium produced mucoid colonies with a greenish tinge on nitrogen-free malate medium and showed appreciable nitrogenase activity in pure culture.

    Isolation and characterization of a new antifungal metabolite ofTrichoderma reesei (1988)
    Springer
    Plant and soil 107 (1988), S. 81-84

    ISSN: 1573-5036
    Keywords: antifungal metabolite ; biological control ; Trichoderma reesei

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract A mycelial extract ofTrichoderma reesei (P-12) was separated into four fractions by high performance liquid chromatography (HPLC). Out of these, two were found to exhibit antifungal activity when tested against plant pathogenic fungi. The level of antifungal compounds was higher in media containing glucose as the carbon source as compared to one containing cellulose. The synthesis of these antifungal compounds started after 3 days of inoculation at 30°C and continued upto 8 days. No further increase was recorded beyond this period.
