In the study "Isolation and characterization of culturable endophytic plant growth-promoting Bacillus species from Mentha longifolia L.", endophytic Bacillus strains were isolated from the root, stem, and leaves of healthy Mentha longifolia L. in Palandöken Mountain, Erzurum-Turkey and evaluated their plant growth promoting parameters such as nitrogen fixation, phosphate solubilization, IAA, siderophore, ACC deaminase, HCN production, and ammonia potential.

The main PGP-properties, namely the ability to solubilize-P and production of IAA, as well as production of siderophores and HCN were examined. Additionally, field trials were conducted on sandy loam soil at El-Tahrir Province during two successive summer seasons to study the effect of co-inoculation with Bradyrhizobium either individually or together with S. marcescens and/or T. harzianum on nodulation

These isolates were screened, in vitro, according to their capacities to produce plant growth promoting substance i.e. IAA, phosphate, potassium solubilization, chitinase activities and hydrogen cyanide. Results indicated that 36 bacterial isolates showed IAA production, 25 HCN production, 57 chitinase activities, 39 phosphate and 105 potassium solubilizers.

In this study a total of 34 bacterial cultures were isolated from Uttarakhand (Rishikesh) acidic soil (pH 5.6) were screened for plant growth promoting traits. Isolations were carried out on nutrient and kings B agar media in which colony forming unit (CFU) count was log10 6.94 and log10 5.04 respectively.

In the present investigation, four efficient Azotobacter isolates were screened for various biocontrol traits and evaluated for its biological deterrent activity against Fusarium solani. Maximum per cent inhibition of 60.25 was observed in AZT-R7 isolate followed by AZTY2 (59.17 %), AZT-J1 (57.77 %) and AZT-G4 (51.47 %). AZT-R7 recorded a maximum siderophore, IAA production and highest N2 fixation of 82.83 per cent, 100.75 μg 50 ml-1 and 10.33 mg g-1 , respectively.

Plant growth promoting rhizobacteria (PGPR) have gained worldwide importance and have been identified in influencing the growth and yield of many plants. On account of that, an attempt was made in the present investigation to study plant growth promoting activities of bacteria isolated from rhizospheric region of different crop fields from khorda district, Odisha, India. A total of nine bacteria was isolated and they were further characterized for their different plant growth promoting activities like production of Indole acetic acid (IAA), HCN, Siderophore & Phosphate solubilization.

A total of sixty isolates were obtained from rhizosphere, nodule and phyllosphere of different crops. These isolates were analysed for some of their plant growth promoting traits like IAA production, phosphate solubilisation, siderophore production, HCN production, ACC utilization and ammonia excretion. Apart from these traits all the isolates were also screened for their growth at different temperatures and salt concentrations. Three promising isolates (MP12, PP1 and UP4) were characterized morphologically, biochemically and on the basis of 16S rRNA gene sequencing.

Rice crop harbours diverse beneficial plant growth promoting diazotrophs which mostly plays a significant role in supplementing not only N fertilizer but also gives indirect benefit to the crops by improving their productivity and immunity. Considering all the benefits from PGP diazotrophs, rice rhizospheric soil samples were collected randomly from 20 different locations of Jorhat district, Assam. Altogether, 53 rhizobacterial cultures were isolated in non-selective TSA media.

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.

An attempt was made to study the different modes of action of the promising Trichoderma spp. from banana rhizosphere collected from different regions of Assam, Mizoram, Meghalaya and Nagaland. The results from the present investigation revealed that all the potential Trichoderma spp. produced IAA, NH3, siderophore and HCN, though at different levels however, the promising Trichoderma spp. were not able to solubilize phosphate on solid medium containing insoluble inorganic phosphorus source.
