increase in pladienolide d production rate using a streptomyces strain overexpressing a cytochrome p450 gene.	pladienolide b and its 16-hydroxylated derivative (pladienolide d) are novel 12-membered macrolides produced by streptomyces platensis mer-11107 showing strong in vitro and in vivo antitumor activity. while pladienolide b is mainly produced by this strain, pladienolide d is produced to a lesser extent. to facilitate the production of pladienolide d by biotransformation, we found that streptomyces bungoensis a-1544 was able to hydroxylate pladienolide b at 16-position. we identified psma from s. ...	2008	18640605
streptomyces sasae sp. nov., isolated from bamboo (sasa borealis) rhizosphere soil.	a novel strain of gram-staining-positive actinobacterium, designated strain jr-39t, was isolated from the rhizosphere soil of bamboo (sasa borealis) sampled in damyang, korea, and its taxonomic position was investigated by a polyphasic approach. the isolate formed flexuous chains of spores that were cylindrical and smooth-surfaced. strain jr-39t grew at 4–37 °c (optimum 28 °c). the ph range for growth was ph 5–10 (optimum ph 6–8) and the nacl range for growth was 0–5 % (w/v) with optimum growth ...	2015	26296574
melanogenic actinomycetes from rhizosphere soil-antagonistic activity against xanthomonas oryzae and plant-growth-promoting traits.	a total of 210 melanogenic actinomycetes were isolated from 75 rhizospheric soils using isp6 and isp7 agar supplemented with antifungal and antibacterial agents. their morphological characteristics and the presence of ll-diaminopimelic acid in whole-cell hydrolyzates revealed that all isolates belonged to the genus streptomyces. their ability to inhibit the growth of 2 pathogenic rice bacteria, xanthomonas oryzae pv. oryzae and xanthomonas oryzae pv. oryzicola, was observed using the agar overla ...	2015	25620622
