Efficacy of High-Altitude Biofilm-Forming Novel Bacillus subtilis Species as Plant Growth-Promoting Rhizobacteria on Zea mays L.

With the global population explosion, the need for increasing crop productivity is reaching its peak. The significance of organic means of cultivation including biofertilizers and biopesticides is undeniable in this context. Over the last few decades, the use of rhizobacteria to induce crop productivity has gained particular interest of researchers. Of these, several Bacillus spp. have been known for their potential plant growth-promoting and phyto-pathogenic actions. Keeping this background in mind, this study was formulated with an aim to unravel the PGPR and phyto-pathogenic potency of Bacillus sp. isolated from extreme environmental conditions, viz. high-altitude waters of Ganges at Gangotri (Basin Extent Longitude Latitude-73° 2' to 89° 5' E 21° 6' to 31° 21' N). Based on recent studies showing the impact of biofilm on bacterial PGPR potency, three novel strains of Bacillus subtilis were isolated on basis of their extremely high biofilm-producing abilities (BRAM_G1: Accession Number MW006633; BRAM_G2: Accession Numbers MT998278-MT998280; BRAM_G3: Accession Number MT998617), and were tested for their PGPR properties like nutrient sequestration, growth hormone production (IAA, GA3), stress-responsive enzyme production (ACC deaminase) and lignocellulolytic and agriculturally important enzyme productions. The strains were further tested for the plethora of metabolites (liquid and VOCs) exuded by them. Finally, the strains both in individually and in an association, i.e. consortium was tested on a test crop, viz. Zea mays L., and the data were collected at regular intervals and the results were statistically analysed. In the present study, the role of high-altitude novel Bacillus subtilis strains as potent PGPR has been analysed statistically.

Marvels of Bacilli in soil amendment for plant-growth promotion toward sustainable development having futuristic socio-economic implications.

Microorganisms are integral components of ecosystems, exerting profound impacts on various facets of human life. The recent United Nations General Assembly (UNGA) Science Summit emphasized the critical importance of comprehending the microbial world to address global challenges, aligning with the United Nations Sustainable Development Goals (SDGs). In agriculture, microbes are pivotal contributors to food production, sustainable energy, and environmental bioremediation. However, decades of agricultural intensification have boosted crop yields at the expense of soil health and microbial diversity, jeopardizing global food security. To address this issue, a study in West Bengal, India, explored the potential of a novel multi-strain consortium of plant growth promoting (PGP) Bacillus spp. for soil bioaugmentation. These strains were sourced from the soil's native microbial flora, offering a sustainable approach. In this work, a composite inoculum of Bacillus zhangzhouensis MMAM, Bacillus cereus MMAM3), and Bacillus subtilis MMAM2 were introduced into an over-exploited agricultural soil and implications on the improvement of vegetative growth and yield related traits of Gylcine max (L) Meril. plants were evaluated, growing them as model plant, in pot trial condition. The study's findings demonstrated significant improvements in plant growth and soil microbial diversity when using the bacterial consortium in conjunction with vermicompost. Metagenomic analyses revealed increased abundance of many functional genera and metabolic pathways in consortium-inoculated soil, indicating enhanced soil biological health. This innovative bioaugmentation strategy to upgrade the over-used agricultural soil through introduction of residual PGP bacterial members as consortia, presents a promising path forward for sustainable agriculture. The rejuvenated patches of over-used land can be used by the small and marginal farmers for cultivation of resilient crops like soybean. Recognizing the significance of multi-strain PGP bacterial consortia as potential bioinoculants, such technology can bolster food security, enhance agricultural productivity, and mitigate the adverse effects of past agricultural activities.

Taxonomic binning and operational taxonomic unit (OTU) prediction of the Illumina sequencing data indicated the abundance Proteobacteria (61%) followed closely by Bacterioidetes (35%). The top two most abundant genera identified, were Sphingobacterium and Acinetobacter respectively. Chemical properties of soil, such as pH, organic carbon content, available nitrogen, phosphorus, and potassium were also analyzed for enabling future researchers to correlate the abundance of microbial taxa with the prevalent conditions. These findings can be effectively used to formulate strategic microbiome engineering through bioaugmentation for a sustainable agricultural system.

Tropical Milky White Mushroom, Calocybe indica (Agaricomycetes): An Effective Antimicrobial Agent Working in Synergism with Standard Antibiotics.

Synergistic effect of mushroom extracts with standard antibiotics against pathogenic bacteria is beneficial for treating infectious diseases. The present investigation tested the antibacterial activity and synergistic effect from an edible mushroom, Calocybe indica, with standard antibiotics. The minimum inhibitory concentration (MIC) of different extracts from C. indica was checked against pathogenic and opportunistic pathogenic bacteria such as Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, S. epidermidis, and Bacillus subtilis using the broth dilution and agar well diffusion method. The agar disc diffusion method, checkerboard study, and growth curve analysis were used to test synergism. The preliminary mechanism of action regarding cellular morphology, membrane permeability, and damage to protein and DNA were evaluated. Maximum antimicrobial activity was found in the methanolic crude extract (MCE) from C. indica, with a MIC value ranging from 5 to 10 mg/mL. It showed a significant increase in the efficiency of ciprofloxacin (CIP) acting synergistically. The fractional inhibitory concentration index (FICI) of MCE was significant for E. coli and S. aureus with values of 0.46 and 0.45 respectively. Results showed an increase in the loss of cell viability, damage to cell membrane permeability, and damage to bacterial protein and DNA as the probable synergistic mechanism of action for the MCE and the antibiotic. HR-LCMS analysis of the MCE showed the presence of phenolic acid, terpenoids, fatty acid ester, and carboxylic acid, which, in combination, increased the bacterial susceptibility. The present study is significant because it considered the methanolic crude extract from C. indica as complementary medicine for infectious diseases.

Target-specific gene delivery in plant systems and their expression: Insights into recent developments.

In order to improve crop plants in terms of their yield, drought resistance, pest resistance, nutritional value, etc., modern agriculture has relied upon plant genetic engineering. Since the advent of recombinant DNA technology, several tools have been used for genetic transformations in plants such as Agrobacterium tumefaciens, virus-mediated gene transfer, direct gene transfer systems such as electroporation, particle gun, microinjection and chemical methods. All these traditional methods lack specificity and the transgenes are integrated at random sites in the plant DNA. Recently novel techniques for gene targeting have evolved such as engineered nucleases such as Zinc Finger Nucleases, Transcription Activator like effector nucleases, Clustered regular interspaced short palindromic repeats. Other advances include improvement in tools for delivery of gene editing components which include carrier proteins, and carbon nanotubes. The present review focuses on the latest techniques for target specific gene delivery in plants, their expression and future directions in plant biotechnology.

Isolation and characterization of Cr (VI) tolerant bacteria from tannery waste and its bioremediation potential.

The East Kolkata wetland, situated in West Bengal, India, is presently being exploited by housing many leather complexes surrounding the zone in and around. High amount of either untreated or partially treated liquid tannery wastes are discharged in the wetland. Treated effluent from some common effluent treatment plant (CETP) showed the presence of Cr (VI) exceeding the limiting concentration. Three different bacterial strains (L1, L2, and L3) were isolated from the treated effluent. Morphological and biochemical characterizations exhibited that they belong to Gram positive Bacillus group. All such strains proved to be chromate tolerant in the concentration ranging from 20 to 50 mg/L. Significant reduction in Cr (VI) was observed in all those strains, especially L3 [86.3% removal corresponding to 30 mg/L initial concentration]. Cytosolic fraction was involved in Cr reductase capacity. Molecular characterization by 16S rDNA genome sequencing of L3 [the most promising isolate, in terms of chromium (VI) tolerance] confirmed that the strain is Bacillus cereus GXBC-1.
