Abstract A Gram-stain-negative, orange-colored bacterium, designated HX-22-17T, was isolated from activated sludge of an agricultural chemical plant in Maanshan, Anhui province, China (118° 52′ E 31° 68′ N). The strain was strictly aerobic, non-endospore forming, non-motile, and ellipse. Growth of the strain was observed at 16–42 °C (optimum between 25 and 30 °C) at pH 6.0–9.0 (optimum at pH 7.0) and with 0–6.0% (w/v) NaCl (optimum at 1.0%). 16S rRNA gene sequence analysis showed...

Abstract The aim of the study is the research and identification of a Streptomyces strain as a new producer of spectinabilin, undecylprodigiosin and metacycloprodigiosin. Among 54 actinomycete isolates isolated from El-Ogbane forest soils in Algeria, only one isolate, designated V002, was selected for its ability to produce prodigiosins. The selected strain was analysed for its ability to produce three different secondary metabolites as well as their biological activities. V002...

Abstract In this study, 18 plant growth-promoting bacterial (PGPB) strains were isolated from the rhizosphere of both Red silk-cotton tree (Bombax malabaricum) and Chinese banyan (Ficus retusa). Culture morphology was observed and genotypic characterization was accomplished by sequencing partial 16S rRNA gene. Plant growth promotion traits and antagonistic activities of the strains against phytopathogenic fungi were evaluated. Among all strains, Bacillus thuringiensis (MN419208)...
