“…Chromium is used in various industrial processes such as for wood preservation, in tannery plants, for electroplating, leather industry, steel and alloys, dye manufacturing and mining. 1,2 Extensive use of chromium, however, has led to pollution problems in water. Chromium concentration has been reported in the range of 0.5 and 270 mg/L in industrial wastewaters.…”

Contamination of water by chromium (Cr) creates serious pollution in terms of the environment and public health, since its different forms become released into air, water, soil and residential areas. In the present work, olive leaf powder (OLP) was evaluated as a novel low-cost sorbent due to its various functional groups such as amide, hydroxyl, carboxyl, and carbonyl which are responsible for the bio-removal of chromium ions from aqueous solutions. The chemical functional groups and microstructure of the OLP bio-sorbent were characterized by the Fourier Transform Infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) techniques. The bio-sorption conditions were optimized as pH 4, contact time 60 min, bio-sorbent dosage 40 g/L, temperature 40 °C. The bio-sorption isotherm was well fitted to the Langmuir model, and the predicted maximum bioremoval capacity of the OLP was estimated at 42.4 mg/g under the above-mentioned experimental conditions. The reuse performance of the bio-sorbent was determined after repeated sorption/desorption cycles. The thermodynamic examination showed that the chromium sorption by OLP was endothermic in thermal nature. The kinetic evaluations indicated that the bio-sorption process well followed with the pseudo-second-order model. The overall results demonstrated that the OLP can be thought as a potential bio-sorbent for cleaning of chromium-contaminated water and wastewater due to its advantageous properties such as low cost, availability, renewable nature, and remarkable bio-sorption capacity.

“…Abiotic stresses are often interrelated and induce general signaling pathways for the regulation of cellular responses aimed at plant adaptation causing similar morphological, physiological, biochemical, molecular, and genetic changes (213)(214)(215). Many studies have shown that various strains of B. subtilis contribute to the protection of different host plants against diverse abiotic stresses leading to the increase of plant growth and productivity (130,197,216,217). Investigations on the mechanisms mediated by B. subtilis on plant stress tolerance are of the most urgent scientific demand in modern plant biology due to the fact that B. subtilis-induced responses against stresses could range from diverse to very specific (130,218).…”

The group bacilli represent the Gram-positive ubiquitous spore-forming bacteria. Their diversity, versatility and the ability of producing diverse secondary metabolites including enzymes created enormous potential for applications in agriculture, biotechnology, environment and medicine. The bacilli are considered as one of the most studied groups of bacteria providing plant growth-promotion and biocontrol of multiple diseases reflecting their vital role in enhancing plants' tolerance to biotic and abiotic stresses. Some of the Bacillus species are available commercially as phytostimulants, biopesticides, and biofertilizers. Genetically engineered plants such as maize, cotton, brinjal with endotoxins producing genes from Bacillus thuringiensis (Bt) has revolutionized agriculture. Many of these applications have been widely adopted in various fields as viable and environmentally friendly alternatives of synthetic chemical fertilizers and pesticides. A better understanding of the biology, ecology, and mechanisms of action of the beneficial strains of bacilli are needed for the development of products to support green biotechnology in agriculture and industries. This report comprehensively reviewed the applications of bacilli in agriculture and industry and discussed their potentials for the development of new products of biotechnological implications.

“…The tree of the microorganism Bacillus strain ANUES03 reveals that this specific microorganism strain has been originated directly from associate degree unknown common antecedent. This unknown common antecedent has additionally given rise to 5 connected strains from several intermediate strains through many genomic variations on varied generations [26][27][28][29][30]. None of those connected strains show serious metal tolerance; which can ensure the genomic variations that had occurred on varied generations.…”

Industrial wastes are capable of polluting the soil and groundwater, are taken into account as a possible environmental polluting agent throughout the earth. Chromium (Cr), a virulent serious metal, could be a major constituent of industrial waste, and its accumulation in soil and water causes serious environmental problems with increasing public concern in India mainly in Telangana. This study deals with isolation and identification of Cr resistance microorganisms isolated from industrial effluents collected from Uppal region, Hyderabad. Cr resistance microorganism was isolated and the identification of the isolates was done by 16s rRNA sequencing followed by BLAST results confirming the novel Bacillus subtilis strain. Moreover, the presence of Chromium reductase enzyme within the isolated microorganism was confirmed by PCR techniques. Bioremediation by microorganisms might offer an alternate or aid standard strategies of Cr metal removal capacity. The novel is known as Cr resistance microorganism would be helpful for the detoxification of heavy metal contaminated industry effluent and metal recovery in the mining method.
