    Biological nitrogen fixation at elevated temperature in different Azospirillum species and strains (1995)
    Springer
    Biology and fertility of soils 20 (1995), S. 260-262 
    Details
    ISSN: 1432-0789
    Keywords: Azospirilla ; Nitrogenase activity ; Elevated temperature ; Acetylene reduction activity ; Azospirillum brasilense ; Azospirillum lipoferum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Geosciences , Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Nitrogenase activity, nitrogenase synthesis, and the growth of four species of Azospirillum were examined at 30°C and 42°C. Azospirillum brasilense Sp 7 did not synthesize nitrogenase at 42°C nor was the enzyme stable at this temperature. In A. lipoferum 708 and A. brasilense 12S the nitrogenase activity was stable at 42°C but the synthesis of nitrogenase was reduced. In A. brasilense Sp 9 the nitrogenase activity was stable and showed the highest C2H2 reduction activity at 42°C.

    Synthesis of xylanase byTrichoderma reesei (1986)
    Springer
    World journal of microbiology and biotechnology 2 (1986), S. 399-403 
    Details
    ISSN: 1573-0972

    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    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.

    Description / Table of Contents: Samenvatting Een belangwekkende bladvlekkenziekte op ‘Composite Jawahar’ maïs, veroorzaakt doorCurvularia clavata Jain, werd waargenomen op de College Farm van de Banaras Hindu University te Benares in september 1969. De schimmel brengt ernstige schade toe aan maïsbladeren en vermindert aanzienlijk de waarde als voedergewas. Een beschrijving van de ziektesymptomen en van de schimmel wordt gegeven.
    Notes: Abstract In September 1969 a leaf spot of maize ‘Composite Jawahar’, incited byC. lavata Jain, was observed at the College Farm of the Banaras Hindu University, Varanasi. The fungus seriously damages maize leaves and considerably reduces its fodder value. The symptoms of the disease and taxonomic characters of the pathogen are being described in detail.

    Plasma hormonal and electrolyte alterations in cycling buffaloes (Bubalus bubalis) during hot summer months (1992)
    Springer
    International journal of biometeorology 36 (1992), S. 151-154 
    Details
    ISSN: 1432-1254
    Keywords: Hormones ; Electrolytes ; Buffaloes ; Summer
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geography , Physics
    Notes: Abstract Plasma levels of progesterone, prolactin, luteinizing hormone, and electrolytes were monitored by radioimmunoassay in ten cycling buffaloes maintained at Punjab Agricultural University, Ludhiana during the hot summer months of June–July. The plasma progesterone concentration ranged from 0.28±0.04 to 3.09±0.03 ng/ml at various stages of the oestrous cycle. Prolactin values ranged from 319±23 to 371±25 ng/ml and LH levels from 0.95±0.05 to 1.35±0.08 ng/ml. Concentrations differed significantly (P⩽0.05) at various stages of the cycle. Levels of electrolytes, viz. Ca+ +, Na+ and K+, were well within the normal range. The high levels of prolactin, progesterone and LH during the hot summer were assessed in relation to poor reproductive efficiency in buffaloes.

    Phosphatase activity during the growth and metamorphosis ofTribolium confusum duval (1964)
    Springer

    Notes: Résumé Nous avons mesuré l'activité des phosphatases acide et alcaline au cours de la croissance et de la métamorphose deT. confusum. L'activité de la phosphatase acide est à son maximum au cours de l'embryogénèse et du stade larvaire. Il est donc possible que cette enzyme soit reliée aux phénomènes de la différentiation cellulaire et de la croissance. L'activité de la phosphatase alcaline est, au contraire, très élevée au cours de la croissance larvaire. Elle serait donc associée à la croissance seule.

    The occurrence of 12, 13-epoxytrichothecenes in seeds of safflower infected with Fusarium oxysporum f. sp. carthami (1977)
    Springer

    Details
    ISSN: 1420-9071

    Topics: Biology , Medicine
    Notes: Summary From the seeds of safflower (Carthamus tinctorius Linn.), infected with Fusarium oxysporum f. sp. carthami, 3 toxic compounds have been isolated in quatities sufficient to cause mycotoxicosis on prolonged ingestion. 2 of these have been identified as diacetoxyscirpenol and T-2 toxin, while the third one has also been partially characterized as a 12, 13-epoxytrichothecene. Additionally, the incidence of secondary fusarial infection of healthy seeds due to contamination with the infected ones has been reported for the first time.

    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.
