Drought tolerant endophytic actinobacteria Streptomyces coelicolor DE07, S. olivaceus DE10 and Streptomyces geysiriensis DE27 were isolated from cultivated plants of arid and drought affected regions of Rajasthan, India. These isolates exhibited plant growth promotion traits and intrinsic water stress tolerance from −0.05 to −0.73 MPa. Maximum auxin(More)
Methylotrophic bacteria were isolated from the phyllosphere of different crop plants such as sugarcane, pigeonpea, mustard, potato and radish. The methylotrophic isolates were differentiated based on growth characteristics and colony morphology on methanol supplemented ammonium mineral salts medium. Amplification of the mxaF gene helped in the(More)
Indigenous phosphate-solubilizing microorganisms (PSM) were studied in the rhizosphere and non-rhizosphere of salt-affected soils. A total of 23 phosphate-solubilizing bacteria (PSB) and 35 phosphate-solubilizing fungi (PSF) were isolated from 19 samples collected from different locations in Karnataka and Madhya Pradesh of India. The counts of PSB and PSF(More)
Halotolerant bacteria associated with Psoralea corylifolia L., a luxuriantly growing annual weed in salinity-affected semi-arid regions of western Maharashtra, India were evaluated for their plant growth-promoting activity in wheat. A total of 79 bacteria associated with different parts viz., root, shoot and nodule endophytes, rhizosphere, rhizoplane, and(More)
The ability of two diazotrophic cyanobacteria Westiellopsis prolifica and Anabaena variabilis were examined to solubilize extracellular insoluble tricalcium phosphate (TCP) and Mussorie rock phosphate (MRP). The two strains exhibited a differential response to insoluble forms of phosphorus used. W. prolifica showed better growth in presence of MRP while A.(More)
The authors have reported the use of nanopolymers for the inhibition of shrimp pathogenic bacteria for aquaculture use. The antimicrobial activity of polyethylene glycols based amphiphilic polymers have different linker molecules such as suberic acid, adipic acid, glutaric acid and dimethyl-5-hydroxyisophthalate on Vibrio harveyi. It was examined by drawing(More)
Antioxidative status, cellular metabolic stress and neurotransmitter enzyme assay as a pollution biomarker in Oreochromis mossambicus collected from Bhima river were investigated. O. mossambicus was collected from 18 different sites of Bhima river, which differ in their extent and type of contamination load. The antioxidative status were determined such as(More)
Abiotic stresses are the foremost limiting factors for agricultural productivity. Crop plants need to cope up adverse external pressure created by environmental and edaphic conditions with their intrinsic biological mechanisms, failing which their growth, development, and productivity suffer. Microorganisms, the most natural inhabitants of diverse(More)
The nitrogen fixing cyanobacterial strains namely Anabaena variabilis (Nostocales, Nostocaceae) and Westiellopsis prolifica (Nostocales, Hapalosiphonaceae) were evaluated for their nitrogen fixation and growth potential in response to different concentrations (10, 20 and 30 mg P) of the alternate insoluble P-sources Mussorie Rock Phosphate and Tricalcium(More)
