An aerobic, yellow-pigmented, facultatively methylotrophic, Gram-staining-negative, non-spore-forming bacterium, designated strain Gm-149(T), was isolated from the rhizosphere of cultivated soybean in India. Cells were motile by gliding. The predominant cellular fatty acids were iso-C(15 : 0), summed feature 3 (comprising iso-C(15 : 0) 2-OH and/or C(16 : 1)(More)
Two isolates from rhizosphere soil of cotton, designated Gh-67(T) and Gh-48(T), which produced large amounts of extracellular polysaccharide and possessed plant-growth-promoting traits, were characterized phenotypically and genotypically. The strains were Gram-negative and cells were non-motile rods that grew optimally at 28°C and grew between pH 4 and 7.(More)
Two yellow-pigmented, Gram-stain-positive, aerobic, motile, short rod-shaped bacteria were isolated from natural teak tree rhizosphere soil and their taxonomic positions were determined by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strains TG-S248(T) and TG-S240 formed a distinct phyletic line within the genus(More)
The potential of bacterial endophytes to improve symbiotic efficiency through synergistic interactions with rhizobia can help to improve nodulation and nitrogen fixation in legume plants. In the present study, we compared the effect of endophytic plant growth-promoting bacteria on nodulation and effective rhizobial symbiosis in soybean. Nodule endophyte(More)
The Janghang smelter in Chungnam, South Korea started in 1936 was subsequently shutdown in 1989 due to heavy metal (loid) pollution concerns in the vicinity. Thus, there is a need for the soil in the area to be remediated to make it usable again especially for agricultural purposes. The present study was conducted to exploit the potential of arsenic(More)
1 Raw soya flour (RSF) in the diet induces pancreatic hypertrophy and hyperplasia in the rat, changes ascribed to production of a high circulating level of cholecystokinin (CCK) due to inhibition of trypsin in the duodenum. Prolonged ingestion results in pancreatic adenomas and carcinomas. 2 L-364, 718, a potent, highly specific CCK antagonist was used to(More)
A wide range of C3 and C4 plant species could acclimatize and grow under the impact of salinity stress. Symbiotic relationship between plant roots and arbuscular mycorrhizal fungi (AMF) are widespread and are well known to ameliorate the influence of salinity stress on agro-ecosystem. In the present study, we sought to understand the phenomenon of(More)
The studies on the biocontrol potential of pink pigmented facultative methylotrophic (PPFM) bacteria other than the genus Methylobacterium are scarce. In the present study, we report three facultative methylotrophic isolates; PPO-1, PPT-1, and PPB-1, respectively, identified as Delftia lacustris, Bacillus subtilis, and Bacillus cereus by 16S rRNA gene(More)
