“…BNF fixes about 2 × 10 11 kg N annually and makes up for about 3/4 of the total N needed for plant growth in the world . Rhizobia inoculants that are derived from nitrogen-fixing bacteria have been applied for decades and have made great achievements in increasing the crop yield . For example, both rhizobacterium Pseudomonas protegens Pf-5 X940 and Pseudomonas stutzeri A1501 utilization promote the available nitrogen content and increase the seeds yield of wheat .…”

Microorganisms colonizing the plant rhizosphere provide a number of beneficial functions for their host. Although an increasing number of investigations clarified the great functional capabilities of rhizosphere microbial communities, the understanding of the precise mechanisms underlying the impact of rhizosphere microbiome assemblies is still limited. Also, not much is known about the various beneficial functions of the rhizosphere microbiome. In this review, we summarize the current knowledge of biotic and abiotic factors that shape the rhizosphere microbiome as well as the rhizosphere microbiome traits that are beneficial to plants growth and disease-resistance. We give particular emphasis on the impact of plant root metabolites on rhizosphere microbiome assemblies and on how the microbiome contributes to plant growth, yield, and disease-resistance. Finally, we introduce a new perspective and a novel method showing how a synthetic microbial community construction provides an effective approach to unravel the plant–microbes and microbes–microbes interplays.

As a ubiquitous enzyme, succinic semialdehyde dehydrogenase contributes significantly in many pathways including the tricarboxylic acid cycle and other metabolic processes such as detoxifying the accumulated succinic semialdehyde and surviving in nutrient-limiting conditions. Here the cce4228 gene encoding succinic semialdehyde dehydrogenase from Cyanothece sp. ATCC51142 was cloned and the homogenous recombinant cce4228 protein was obtained by Ni-NTA affinity chromatography. Biochemical characterization revealed that cce4228 protein displayed optimal activity at presence of metal ions in basic condition. Although the binding affinity of cce4228 protein with NAD + was about 50-fold lower than that of cce4228 with NADP + , the catalytic efficiency of cce4228 protein towards succinic semialdehyde with saturated concentration of NADP + is same as that with saturated concentration of NAD + as its cofactors. Meanwhile, the catalytic activity of cce4228 was competitively inhibited by succinic semialdehyde substrate. Kinetic and structural analysis demonstrated that the conserved Cys262 and Glu228 residues were crucial for the catalytic activity of cce4228 protein and the Ser157 and Lys154 residues were determinants of cofactor preference.

BACKGROUNDSustainable wastewater management mostly implicates treatment cost, viability, and performance of an appropriate system, in addition to reuse and recycling, to meet the present social needs. In the current study, algal technology was coupled with paddy‐soaked rice mill wastewater (PSRMW) treatment to enhance the efficient treatment and economic feasibility of algal‐based eco‐friendly products. Initially, the selected microalgae, Chlorella pyrenoidosa, were cultured in raceway ponds using PSRMW as a growth medium. Then, the harvested live algal biomass was carried forward to subsequent study, after primary seedling experiments of Indian okra (Abelmoschus angulosus), which involves soil amendment treatment samples T1 (control soil – no amendment), T2 (soil + live algal biomass), and T3 (soil + chemical fertilizer).RESULTSThe maximum ammoniacal nitrogen (NH3‐N) and phosphate (PO4‐P) removal of ~70% (average yield coefficient (YN): 5.78 mg biomass mg−1 of N) and ~65% (YP: 14.13) were obtained from the phycoremediation experiments. The biochemical composition such as lipid, protein, and carbohydrate contents of harvested biomass were recorded as ~35%, ~30%, and ~9%, respectively. From the biofertilizer experiments, the maximum absolute growth rate (AGR) of 0.40 day−1 was obtained in T2 plants with better growth characteristics of chlorophyll, fresh and dry shoot, root weights (which were ~30% more than that of T3), and control soil (T1) does not exhibit the plant growth as the soil was low in nutrients.CONCLUSIONThe present study revealed the phycoremediation potential of C. pyrenoidosa in PSRMW treatment and the application of produced algal biomass as a soil amendment for the growth of A. angulosus. © 2020 Society of Chemical Industry (SCI)
