“…The MSSA-10 was also positive for IAA production (despite the addition of salt) which was further enhanced with the addition of tryptophan. The ACC deaminase activity exhibited by MSSA-10 indicated that the strain could be applied as a PGPR as the enzyme is a key regulator of plant ethylene level (Glick et al 2007;Mahmood et al 2017). The natural Planomicrobium sp.…”

Aims The current study was aimed to evaluate the beneficial effects and bioremediation potential of a Cd‐tolerant bacterial strain, Serratia sp. CP‐13, on the physiological and biochemical functions of Linum usitatissimum L., under Cd stress. Methods and Results The bacterial strain was isolated from the wastewater collection point of Chakera, Faisalabad, Pakistan, as this place contains industrial wastewater of the Faisalabad region. The Serratia sp. CP‐13, identified through 16S rRNA gene sequence analysis, exhibited a significant phyto‐beneficial potential in terms of in vitro inorganic phosphate solubilization, indole‐3‐acetic acid production and 1‐aminocyclopropane‐1‐carboxylic acid deaminase activity. Effects of Serratia sp. CP‐13 inoculation on L. usitatissimum were evaluated by growing the plants in CdCl2 (0, 5 or 10 mg kg−1 dry soil)‐spiked soil. Without inoculation of Serratia sp. CP‐13, Cd stress significantly reduced the plant biomass as well as the quantity of proteins and photosynthetic pigments due to enhanced H2O2, malondialdehyde (MDA) contents and impaired nutrient homeostasis. Subsequently, Serratia sp. CP‐13 increased the plant fresh and dry biomass, plant antioxidation capacity, whereas it decreased the lipid peroxidation under Cd stress. In parallel, Serratia sp. inoculation assisted the Cd‐stressed plants to maintain an optimum level of nutrients (K, Ca, P, Mg, Fe and Mn). Conclusions The isolated bacterial strain (Serratia sp. CP‐13) when applied to Cd‐stressed L. usitatissimum inhibited the Cd uptake, reduced Cd‐induced lipid peroxidation, maintained the optimum level of nutrients and thereby, enhanced L. usitatissimum growth. The analysis of bio‐concentration and translocation factor revealed that L. usitatissimum with Serratia sp. CP‐13 inoculation sequestered Cd in plant rhizospheric zone. Significance and Impact of the Study Serratia sp. CP‐13 inoculation is a potential candidate for the development of low Cd‐accumulating linseed and could be used for phytostabilization of Cd‐contaminated rhizosphere/soil colloids.

Aims This study builds upon the premise that roots culture distinct bacteria at specific stages of plant growth to benefit of specific microbial services needed at that particular growth stage. Accordingly, we hypothesized that the co‐inoculation of beneficial microbes with distinct properties at specific stages of plant development would enhance plant performance. Methods and Results The chosen microbes were Bacillus pumilus, Bacillus amyloliquefaciens, Bacillus mojavensis and Pseudomonas putida. These microbes were selected based on their specific services ranging from nutrient solubilization, root growth promotion and disease resistance, and were applied to the roots of tomato plants at specific time points when those services were needed the most by the plant. Laboratory and greenhouse studies were conducted to evaluate the effects of co‐inoculation at specific stages of development compared to single microbial applications. Conclusion In general, the combination of three microbes gave the highest biomass and yield without the presence of disease. Applications of three microbes showed the highest root/shoot ratio, and applications of four microbes the lowest ratio. Pseudomonas putida significantly increased fruit macronutrient and micronutrient contents. Significance and Impact of the Study Our studies suggest that co‐inoculation of three or four microbes is a good strategy for healthy crop production.
