| 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 |
| antibacterial activity composition of the fermentation broth of streptomyces djakartensis nw35. | the new compound z-4-2 was isolated from the fermentation broth of streptomyces djakartensis nw35, together with the known compound n-acetyltryptamine (z-9-2) by bioassay-guided fractionation. its chemical structure was elucidated as (e)-2-methoxy-1,4 naphthoquinone-1-oxime (z-4-2) mainly by nmr analyses and ms spectral data. their antibacterial activities against bacteria were evaluated by the filter paper method. the results of indicated that these compounds possess significant antibacterial a ... | 2013 | 23455667 |
