Growth Promoting

The plant growth-promoting rhizobacterium Bacillus cereus RS87 was previously reported to promote plant growth in various crops in both greenhouse and field trials. To apply as a plant growth promoting agent with practical use, it is essential to ease the burden of routine preparation of a fresh suspension of strain RS87 in laboratory. The objectives of this study were to investigate the feasibility of film-coating seeds with B. cereus RS87 spores for early plant growth enhancement and to reveal the indoleacetic acid (IAA) production released from strain RS87. The experiment consisted of the following 5 treatments: nontreated seeds, water-soaked seeds, film-coated seeds, seeds soaked with vegetative cells of strain RS87, and film-coated seeds with strain RS87 spores. Three experiments were conducted separately to assess seed emergence, root length, and plant height. Results showed that both vegetative cells and spores of strain RS87 significantly promoted (P ≤ 0.05) seed emergence, root length and plant height over the control treatments. The strain RS87 also produced IAA. In conclusion, the film coating of seeds with spores of B. cereus RS87 demonstrated early plant growth enhancement as well as seeds using their vegetative cells. IAA released from strain RS87 would be one of the mechanisms for plant growth enhancement.

Rapidly increasing worldwide industrialization has led to many environmental problems by the liberation of pollutants such as heavy metals. Day by day increasing metal contamination in soil and water can be best coped by the interaction of potential plant growth promoting rhizobacteria for plant growth. The effect of plant growth promoting rhizobacteria (PGPR) treatment on growth of chilli plant subjected to heavy metal stress was evaluated. Growth of chilli plant was examined with inoculation of two isolated PGPR (Lysinibacillus varians and Pseudomonas putida) under cadmium (30 ppm), lead (150 ppm) and the combination of heavy metal (Cd+Pb) stress condition. Among these two bacteria L. varians produced slightly better plant growth enhancement. Different growth parameters of chilli plants were reduced under heavy metal stress. Whereas, Cd and Pb tolerant PGPR inoculation, in root associated soil, enhanced plant growth development under test heavy metal contaminated soil. So, these PGPRs may easily be used as bio-fertilizers which will nullify the adverse effect of heavy metal on plant growth.

Actinobacteria were isolated from rhizosphere soil and its plant growth-promoting ability was tested. Actinobacteria were screened for promoting plant growth by phosphate and zinc solubilization, gibberellin, siderophore, HCN and indole-3-acetic acid production. The abiotic stresses of all the isolates were tested for parameters such as pH, temperature and NaCl. Upon screening, a potent actinobacteria named Streptomyces sp. ZS-18 was isolated and identified based on the colony characteristics. The potent strain solubilized both the zinc oxide (26 ± 0.75mm) and zinc carbonate (22 ± 0.88mm). The utilization of gibberellic acid (80μg/ml) by the potential strain ZS-18 showed maximum production measured by optical density value of 0.179. The growth of the green gram plant was determined by shoot, root, total length, number of leaves and chlorophyll estimation of the leaves. Streptomyces sp. ZS-18 showed good growth on ISP 1, ISP 2, ISP 3, ISP 5 and ISP 7 medium and moderate growth was observed in ISP 4 and ISP 6 medium. In addition, Actinobacteria were tested for antagonistic activity against plant pathogens. The isolate ZS-18 in the pot trial experiment showed increased growth in comparison with control and cow dung manure.
