diversity and characterization of culturable bacterial endophytes from zea mays and their potential as plant growth-promoting agents in metal-degraded this study, we evaluated the phylogenetic diversity of culturable bacterial endophytes of zea mays plants growing in an agricultural soil contaminated with zn and cd. endophytic bacterial counts were determined in roots and shoots, and isolates were grouped by random amplified polymorphic dna and identified by 16s ribosomal rna (rrna) gene sequencing. endophytes were further characterized for the production of plant growth-promoting (pgp) substances, such as nh3, siderophores, indol-3-acetic ...201425053283
frigoribacterium endophyticum sp. nov., an endophytic actinobacterium isolated from the root of anabasis elatior (c. a. mey.) schischk.a novel endophytic actinobacterium, designated egi 6500707(t), was isolated from the surface-sterilized root of a halophyte anabasis elatior (c. a. mey.) schischk collected from urumqi, xinjiang province, north-west china, and characterized using a polyphasic approach. cells were gram-stain-positive, non-motile, short rods and produced white colonies. growth occurred at 10-45 °c (optimum 25-30 °c), at ph 5-10 (optimum ph 8) and in presence of 0-4% (w/v) nacl (optimum 0-3%). the predominant menaq ...201525609679
frigoribacterium mesophilum sp. nov., a mesophilic actinobacterium isolated from bigeum island, korea.a taxonomic study was performed on strain msl-08t, which was isolated from a soil sample collected from bigeum island. the novel isolate was aerobic and gram-positive. cells were short and motile rods. growth temperature ranged from 20 to 28 degrees c and the ph for growth ranged from 6.5 to 12.0. the optimum growth temperature and ph were 28 degrees c and 7.3, respectively. the predominant menaquinone was mk-9. cell wall analysis showed b-type peptidoglycan containing 2,4-diaminobutyric acid, a ...200818676471
glaciihabitans tibetensis gen. nov., sp. nov., a psychrotolerant bacterium of the family microbacteriaceae, isolated from glacier ice water.a gram-stain-positive, aerobic, non-spore-forming, short-rod-shaped bacterium, designated strain mp203(t), was isolated from ice water of midui glacier in tibet autonomous region, china. the strain was psychrotolerant, growing at 0-25 °c. 16s rrna gene sequence analysis showed that strain mp203(t) was most similar to frigoribacterium faeni nbrc 103066(t), compostimonas suwonensis kacc 13354(t), frigoribacterium mesophilum kctc 19311(t), marisediminicola antarctica cctcc ab 209077(t) and alpinimo ...201424158943
description of galbitalea soli gen. nov., sp. nov., and frondihabitans sucicola sp. nov.bacterial strains kis82-1(t) and grs42(t) were isolated from soil and from sap of acer mono, respectively, in the republic of korea. both strains were aerobic, gram-stain-positive, mesophilic, rod-shaped and motile. phylogenetically, both strains belonged to the family microbacteriaceae of the phylum actinobacteria. the 16s rrna gene sequence of strain kis82-1(t) showed the highest similarity to those of frondihabitans peucedani rs-15(t) (97.6%), frigoribacterium mesophilum msl-08(t) (97.2%) and ...201424132916
subtercola boreus gen. nov., sp. nov. and subtercola frigoramans sp. nov., two new psychrophilic actinobacteria isolated from boreal groundwater.psychrophilic actinobacterial isolates from permanently cold groundwater in finland were characterized using a polyphasic approach. growth on agar plates was observed at temperatures down to -2 degrees c, with an optimum at 15-17 degrees c, but no growth was observed at 30 degrees c. the peptidoglycan type was b2y and the characteristic diamino acid was diaminobutyric acid. the cell wall sugars of strain k265t were rhamnose, ribose, xylose and mannose and those of strain k300t were glucose, rham ...200011034481
compostimonas suwonensis gen. nov., sp.nov., isolated from spent mushroom compost.strain smc46t, a gram-positive, aerobic, non-motile, short rod-shaped bacterium, was isolated from spent mushroom compost sample collected in the suwon region, south korea. 16s rrna gene sequence analysis revealed that strain smc46t was a member of the family microbacteriaceae, however, formed an independent branch separate from other genera within the family microbacteriaceae. sequence similarity levels between strain smc46t and other members of the family microbacteriaceae were below 97%, show ...201122140170
frigoribacterium faeni gen. nov., sp. nov., a novel psychrophilic genus of the family microbacteriaceae.the taxonomic position of five actinobacterial strains isolated from dust, an animal shed, the air inside a museum and soil was investigated using a polyphasic approach. the growth characteristics were unusual for actinomycetes. optimal growth was at temperatures ranging from 2 to 10 degrees c. after small-step adaptation (5 degrees c steps) to higher temperatures, the strains were also able to grow at 20 degrees c. cell wall analyses revealed that the organisms showed a hitherto undescribed, ne ...200010826823
