Finding solutions to global issues like food security entails greater use of chemicals fertilizers, pesticides, fungicides etc. posing serious risks of soil salinity, heavy metal bioaccumulation. PGPR produce enzyme ACC deaminase which degrades (ACC) 1- aminocyclopropane-1-carobylic acid the immediate precursor of the plant growth hormone ethylene, into α-ketobutyrate and ammonia, thus lowering the level of ethylene in a developing or stressed plant. In the present study, three rhizobacterial strains were isolated from rhizospheric soil of mustard plant in Allahabad region.

An investigation was carried out to isolate bacterial endophytes from small millets that have the ability to produce phytohormones like indole-3-acetic acid (IAA), gibberellic acid (GA), cytokinin and1-aminocyclopropane-1-carboxylate (ACC) deaminase. Thirty two bacterial endophytes are isolated from small millets and among thirty two isolates, twenty isolates produced indole-3-acetic acid (IAA) in the range of 96.70 μg to 254.95 μg and the isolate KMS1 produced significantly highest concentration of IAA (254.95 μg) followed by FMR3 (231.87μg).

Trichoderma species, a class of plant beneficial fungi, may provide opportunistic symbionts to induce plant tolerance to abiotic stresses. Here, we determined the possible mechanisms responsible for the indole acetic acid (IAA) and 1-aminocyclopropane-1-carboxylate-deaminase (ACC-deaminase) producing strain of Trichoderma longibrachiatum T6 (TL-6) in promoting wheat (Triticum aestivum L.) growth and enhancing plant tolerance to NaCl stress.

Environment pollution and the food shortage are the biggest problem faced by human beings. As the world population increase food requirement also increases. To fulfil the requirement of food the farmers are dependent on the chemical fertilizers which are harmful for environment. Thus the alternate to these problems are the use of biofertilizers.

Fluorescent pseudomonad bacteria, a major constituent of Rhizobacteria, enhance the plant growth through diverse mechanisms. The association between plant and fluorescent pseudomonad bacteria contributes to the successful thriving of plants in extreme environments featured by moisture stress. The enzyme has been noticed in a few numbers of bacteria and which helps the plant growth and development during biotic and abiotic stress situations with the depletion of stress levels of ethylene production in plant system.

Stress tolerant Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance plant growth under stress condition. In our present study, 32 stress tolerant PGPR strains (8 Rhizobium. 8 Pseudomonas, 8 KRB, 8ZSB) were isolated from the rhizosphere soils of blackgram crop and screened for their ACC deaminase and Exopolysaccharide (EPS) production. Out of 32 isolates four isolates (1 Rhizobium. 1 Pseudomonas, 1 KRB, 1 ZSB) were selected on the basis of their ACC deaminase activity and Exopolysaccharide production.

An attempt was made to isolate and characterize the desiccation tolerant rhizobacteria from arid regions of Karnataka. A total of nine desiccation tolerant rhizobacteria were isolated from soil samples collected from arid regions of Chitradurga, Gadag and Koppal districts. These isolates were further subjected to morphological and biochemical studies. The Gram staining study of the nine isolates revealed thatCHI-1, CHI-2, CHI-3, and CHI-5 are Gram negative. The other isolates viz., CHI-4, GAD-1, GAD-2, KOP-1 and KOP-2 are Gram positive.

An attempt was made to screen forty native AM fungal isolates from the soybean rhizosphere of Belagavi and Dharwad districts based on their peroxidise activity and total dry matter accumulation in soybean under the restricted water regime of -500 kPa. Top three fungal isolates viz., UASDAMFS15, UASDAMFS25 and UASDAMFS36 tentatively identified as G. maculosum, G. manihotis and G. globiferum respectively. For pot culture studies three irrigation regimes were maintained viz., -33 kPa -500 kPa and -1000 kPa. An experiment was laid out in completely randomized design with factorial concept.

Plant Growth Promoting Rhizobacteria (PGPR) are a group of rhizospheric bacteria, found in association with plant roots and enhance the growth of plant directly or indirectly. To isolate multi-trait PGPR, total 7 soil sample were collected from sugarcane rhizosphere with diverse previous cropping pattern. Total 38 distinct isolates were obtained in pure culture from above collected samples, were screened for their ability of plant growth promoting characters in in vitro conditions. Out of this, 100% showed antagonistic potential, 55.26%, 42.11% and 52.

In recent years due to drought yield of crop is adversely affected. In this context to increase the crop yield by utilising drought prone region, influences of moisture stress tolerant rhizobacteria on growth parameter of sorghum plant were examined under moisture stress conditions. Four autochthonous moisture stress tolerant bacterial strain isolated from semiarid region identified as Serratia marcescens strain L1SC8, Pseudomonas putida strain L3SC1, Enterobacter cloacae strain L1CcC1 and Serratia marcescens strain L2FmA4.

In the present investigation total 167 non rhizobial endophytic bacterial isolates from roots of chickpea were collected and screened for qualitative P solubilization. Out of these 37 potential bacterial endophytic isolates from root were selected for further quantitative Psolubilization, Indole acetic acid (IAA), Gibberelic acid and ACC deaminase production. High P-solubilization was recorded in isolate RBR20 (20.60 mg100ml1 ). Maximum amount of IAA was produced by isolate LCRE 9 (39.60 μgml-1 ) (presence of tryptophan) and RBR164 (19.93 μgml-1 ) (absence of tryptophan).

The present study was conducted to evaluate the in vitro efficacy of native Trichoderma spp. against Pythium spp. and Rhizoctonia solani (Kuhn.) causing damping-off disease in Tomato. One hundred eighty soil samples were collected from 11 districts of Meghalaya and ninety seven Trichoderma isolates were obtained. Rapid screening against damping off pathogens (Pythium spp. and R. solani) of tomato revealed that 20 isolates showed maximum antagonism and subsequently 20 best isolates were selected for further analysis.

Pulses being important source of protein and micronutrients find its place in national food security. Plant probiotic microbes play an important role in producing safe and nutritious pulses. In this work we characterized plant probiotic yeast from different sources and investigated its multifunctional activity in promoting the growth of black gram. Of the twenty isolates, two isolates one from the seeds of pomegranate (POY5) and the other one from grapes (GRY4) were selected for the study.
