    Production and potential applications of a xylanase from a new strain of Streptomyces cuspidosporus (2000)
    Springer
    World journal of microbiology and biotechnology 16 (2000), S. 257-263 
    Details
    ISSN: 1573-0972
    Keywords: Paper pulp ; poultry feed ; pretreatment ; Streptomyces ; wheat bran ; Xylanase
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract Enzyme production by a new mesophilic Streptomyces isolate was investigated which grew optimally on 1% (w/v) xylan and 10% (w/v) wheat bran at pH 7 and 37 °C. Xylan induced only CMCase (0.29 U/ml) besides xylanase (22–35 U/ml, 40–49 U/mg protein). Wheat bran induced xylanase (105 U/ml, 17.5 U/mg protein), CMCase (0.74 U/ml), β-xylosidase (0.009 U/ml), β-glucosidase (0.026 U/ml), α-L-arabinofuranosidase (0.049 U/ml), amylase (1.6 U/ml) and phytase (0.432 U/ml). The isolate was amenable to solid state cultivation and produced increased levels of xylanase (146 U/ml, 28 U/mg protein). The pH and temperature optima of the crude xylanase activity were 5.5 and 65 °C respectively. The pI was 6.0 as determined by PEG precipitation. The crude enzyme was applied in treatment of paper pulp and predigestion of poultry feed and was found to be effective in releasing sugars from both and soluble phosphorus from the latter.

    Chitinolytic actinomycetes from a Brazilian tropical soil active against phytopathogenic fungi (2000)
    Springer
    World journal of microbiology and biotechnology 16 (2000), S. 109-110 
    Details
    ISSN: 1573-0972
    Keywords: Chitinolytic activity ; Streptomyces ; tropical soil
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract Five Streptomyces spp. isolated from a Brazilian forest soil showed endochitinase activity in the alkaline range with optima between 40 and 50 °C. Three were highly active against three phytopathogenic fungi by in vitro experiments. Preliminary experiments suggested that the isolates may belong to a new taxon.

    Preliminary characterization of some Streptomyces species from four Tanzanian soils and their antimicrobial potential against selected plant and animal pathogenic bacteria (2000)
    Springer
    World journal of microbiology and biotechnology 16 (2000), S. 595-599 
    Details
    ISSN: 1573-0972
    Keywords: Animal pathogens ; antibiotics ; antimicrobial activity ; characterization ; plant pathogens ; Streptomyces
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract This study was undertaken to characterize Streptomyces strains occurring in some soils of Tanzania as well as to evaluate their potential to synthesize antimicrobial compounds. Six main classes of isolates were observed according to the colour of aerial mycelium. These were gray, cream, blue, pink, red, and white. The gray colour class dominated. About 65% of the isolates produced soluble pigments of various colours while about 33% of the isolates did not produce any soluble pigments. Brown coloured soluble pigments dominated. About 57% of the isolates had spiral spore chains. Some Streptomyces isolates displayed strong (〉 30 mm inhibition zone), moderate (20–30 mm), or weak (〈 20 mm) antibiosis against the plant/animal pathogenic bacteria tested. Other isolates did not show any antibiosis against any of the test pathogens. The plant pathogens CMM IPO 542 (Clavibacter michiganensis ssp. michiganensis) and Xanthomonas vascatoria were inhibited by most of the Streptomyces isolates. Xanthomonas oryzae pv. oryzae and X. campestris were inhibited by the least number of the Streptomyces isolates. Most of the animal pathogens tested seemed to show resistance to the antibiotics produced by some of the Streptomyces isolates which had shown high activity against the plant pathogens.

    Activity of North Jordan soil streptomycete isolates against Candida albicans (2000)
    Springer
    World journal of microbiology and biotechnology 16 (2000), S. 139-142 
    Details
    ISSN: 1573-0972
    Keywords: Activity ; Candida albicans ; Streptomyces
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract Eighteen percent of 116 different isolates of Streptomyces recovered from soils of northern Jordan showed activity against Candida albicans. The recovered isolates were distributed into three groups according to the diameter of the inhibition zone on the agar plate: group 1 (5–10 mm, slightly active); group 2 (11–15 mm, moderately active); and group 3 (16–35 mm, highly active). Isolates of group 3 were further grouped into four sub-groups and were culturally and morphologically identified. The u.v. spectra of the fermentation broth for the isolates in sub-group 4 were determined, and showed absorbance peaks ranging between 230 and 300 nm.

    Effect of amino acids on production of xylanase and pectinase from Streptomyces sp. QG-11-3 (2000)
    Springer
    World journal of microbiology and biotechnology 16 (2000), S. 211-213

    ISSN: 1573-0972
    Keywords: Amino acids ; pectinase ; Streptomyces ; xylanase

    Notes: Abstract Xylanase and pectinase production by Streptomyces sp. QG-11-3 was stimulated by DL-norleucine, L-leucine, DL-isoleucine, L-lysine monohydrochloride and DL-β-phenylalanine by up to 3.72- and 2.78-fold, respectively, whereas the combination of DL-norleucine, L-leucine and DL-isoleucine synergistically stimulated the xylanase and pectinase production by up to 6.72- and 5.62-fold, respectively. Glycine, DL-norvaline, DL-methionine, and DL-aspartic acid showed no significant stimulatory effect on enzyme production.
