    Comparison of the xylanolytic and cellulolytic activities of Cellulomonas (1982)
    Springer
    Applied microbiology and biotechnology 14 (1982), S. 169-173 
    Details
    ISSN: 1432-0614
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Summary A highly cellulolytic Cellulomonas mutant, CS1-17, has been shown to be improved over the original parent strain, CS1-1, with respect to xylanase and β-xylosidase activities. From induction studies during growth on xylan, crystalline cellulose and carboxymethylcellulose it can be deduced that, although both activities have been similarly affected by the mutation, xylanolytic activity is distinct from cellulolytic activity; however, the possibility of some cross-specificity has not been eliminated.

    Production of glycosidase activity by Cellulomonas during growth on various carbohydrate substrates (1983)
    Springer
    Applied microbiology and biotechnology 18 (1983), S. 100-102 
    Details
    ISSN: 1432-0614

    Thema: Biologie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Summary A Cellulomonas mutant previously shown to be improved over its parent with respect to cellulolytic and xylanolytic activities, has now been shown to produce enhanced activity towards galactomannan. The mutant produced a range of glycosidase activities during growth on various carbohydrate substrates. Changes in the proportions of β-glucosidase, β-mannosidase, β-xylosidase and α-arabinosidase levels with variation in growth substrate indicate specific produciton patterns for these four enzymic activities.

    Detection and assay of xylanolytic enzymes in a Cellulomonas isolate (1980)
    Springer
    Biotechnology letters 2 (1980), S. 363-368 
    Details
    ISSN: 1573-6776
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Summary The accuracy of xylanase assay was tested and improved. The assay was used to monitor xylanase production by a Cellulomonas isolate and to demonstrate that this activity is distinct from the organism's β-xylosidase activity.

    The hydrolysis of bagasse hemicelluloses by selected strains of Cellulomonas (1981)
    Springer
    Biotechnology letters 3 (1981), S. 39-44 
    Details
    ISSN: 1573-6776
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Summary The enhanced cellulolytic activity of a Cellulomonas mutant has been shown to apply also to its ability to hydrolyse xylan-containing hemicelluloses. The hydrolytic activity was directly proportional to the xylose content in the hemicellulose substrate.

    Product inhibition ofTrichoderma reesei andCellulomonas glycosidase activities (1983)
    Springer
    Biotechnology letters 5 (1983), S. 689-692 
    Details
    ISSN: 1573-6776
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Summary A comparison has been made of the effects of glucose, xylose and arabinose on the ability ofTrichoderma reesei andCellulomonas preparations to hydrolyse the glycosides of these three sugars. The stronger resistance of theCellulomonas preparations to product inhibition meant that these were comparable to theT.reesei preparations in the presence of 500mM sugar product.

    Notizen: Summary A Cellulomonas strain, with potential for saccharification of sugar cane bagasse, has been found to possess a range of glycosidase activities which could be necessary for effective hydrolysis of the hemicellulose fraction of the bagasse.

    Maximization of Candida utilis cytochromes by pulse additions of ethanol to continuous cultures (1979)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 21 (1979), S. 803-820 
    Details
    ISSN: 0006-3592
    Schlagwort(e): Chemistry ; Biochemistry and Biotechnology

    Thema: Biologie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Candida utilis was grown with glucose as growth-limiting carbon source in batch culture, steady-state continuous culture, and non-steady-state continuous culture. High cytochrome concentrations were routinely recorded in cells harvested in the latter stages of batch culture. They were occasionally recorded in cells from imprecisely controlled steady-state cultures, but precise control of the steady-state dissolved oxygen tension stabilized the cytochromes at relatively low levels. Controlled non-steady-state continuous cultures, imposed by pulse additions of ethanol, routinely produced cells with high cytochrome concentrations. A mechanism is proposed whereby maintenance of cytochrome derepression in continuous culture is dependent upon indefinitely prolonging an “overshoot” response in gene expression.

    Numerical analysis of reflectance spectra (1967)

    Notizen: (1) Samples of yeast which varied over an arbitrary 0-100% scale with respect, to cytochrome concentration were prepared. (2) The reflectance spectrum of each sample was scanned. (3) These reflectance spectra were analyzed numerically on a digital computer to determine the bandwidths and intensities as a function of cytochrome concentration. Band shapes using the profiles of Cauchy, Gauss, and Giovanlelli were used. The correlations may be used to estimate cytochrome concentrations with a standard deviation of about 3%.
