| [novel l-glutamate oxidase producing organisms: streptomyces litmocidini and streptomyces cremeus]. | two novel strains i.e. streptomyces cremeus 510 and streptomyces litmocidini 447 producing l-glutamate oxidase were isolated from soil samples and identified. mathematical design of the experiments made it possible to optimize the fermentation medium composition which provided at least a 5-fold increase of the strain l-glutamate oxidase activity by comparison with the initial activity in the standard medium. | 1998 | 9606498 |
| screening of endophytic streptomycetes isolated from parthenium hysterophorus l. against nosocomial pathogens. | parthenium hysterophorus l. is an obnoxious weed of the family asteraceae recognized for its detrimental effects and significant economic losses to agriculture. in this study 42 endophytic streptomycetes strains were isolated from its roots and leaves. the isolates were identified by morphological, microscopic, biochemical and physiological characterization as members of genus streptomyces. in 16s rrna gene sequencing the selected isolates exhibited maximum similarity with streptomyces rochei (9 ... | 2013 | 23455197 |
| construction and characterization of new cloning vectors derived from streptomyces griseobrunneus plasmid pbt1 and containing amikacin and sulfomycin resistance genes. | three cryptic plasmids, designated pbt1 (5.6 kb), pbt2 (9.7 kb), and pbt3 (16.6 kb), were isolated from streptomyces griseobrunneus isp5066 and physically characterized. pbt1 and pbt2, which differ by a 4.1-kb segment, are high copy-number plasmids (40-100 copies per chromosome) that coexist with each other. pbt3 is a low copy-number plasmid. vectors containing amikacin (or kanamycin) and sulfomycin (or thiostrepton) resistance genes from streptomyces litmocidini isp5164 and streptomyces viridoc ... | 1986 | 3714878 |
