Bacillus subtilis: a universal cell factory for industry, agriculture, biomaterials and medicine

Microbial Cell Factories, Journal Year: 2020, Volume and Issue: 19(1)

Published: Sept. 3, 2020

Due to its clear inherited backgrounds as well simple and diverse genetic manipulation systems, Bacillus subtilis is the key Gram-positive model bacterium for studies on physiology metabolism. Furthermore, due highly efficient protein secretion system adaptable metabolism, it has been widely used a cell factory microbial production of chemicals, enzymes, antimicrobial materials industry, agriculture, medicine. In this mini-review, we first summarize basic tools expression systems bacterium, including traditional methods novel engineering systems. Secondly, briefly introduce applications in chemicals advantages, mainly focusing some noteworthy products recent progress B. subtilis. Finally, review also covers such additives antimicrobials, biofilm spore formation. We hope provide an overview novice researchers area, offering them better understanding applications.

Bacillus subtilisimpact on plant growth, soil health and environment: Dr. Jekyll and Mr. Hyde

Journal of Applied Microbiology, Journal Year: 2022, Volume and Issue: 132(5), P. 3543 - 3562

Published: Feb. 9, 2022

Abstract The increased dependence of farmers on chemical fertilizers poses a risk to soil fertility and ecosystem stability. Plant growth-promoting rhizobacteria (PGPR) are at the forefront sustainable agriculture, providing multiple benefits for enhancement crop production health. Bacillus subtilis is common PGPR in that plays key role conferring biotic abiotic stress tolerance plants by induced systemic resistance (ISR), biofilm formation lipopeptide production. As part bioremediating technologies, spp. can purify metal contaminated soil. It acts as potent denitrifying agent agroecosystems while improving carbon sequestration process when applied regulated concentration. Although it harbours several antibiotic genes (ARGs), reduce horizontal transfer ARGs during manure composting modifying genetic makeup existing microbiota. In some instances, affects beneficial microbes rhizosphere. External inoculation B. has both positive negative impacts endophytic semi-synthetic microbial community. Soil texture, type, pH bacterial concentration play crucial regulation all these processes. amendments consortia produced engineering could be used lessen effect diversity. complex plant–microbe interactions decoded using transcriptomics, proteomics, metabolomics epigenomics strategies which would productivity well-being more attributes similar character Dr. Jekyll plant growth, health environment akin Mr. Hyde.

Influence of microbial inoculants on co-composting of lignocellulosic crop residues with farm animal manure: A review

Journal of Environmental Management, Journal Year: 2021, Volume and Issue: 302, P. 114088 - 114088

Published: Nov. 16, 2021

The rapidly developing agro-industry generates huge amounts of lignocellulosic crop residues and animal manure worldwide. Although co-composting represents a promising cost-effective method to treat various agricultural wastes simultaneously, poor composting efficiency prolongs total completion time deteriorates the quality final product. However, supplementation feedstock with beneficial microorganisms can mitigate these negative effects by facilitating decomposition recalcitrant materials, enhancing microbial enzyme activity, promoting maturation humus formation during process. Nevertheless, influence inoculation may vary greatly depending on certain factors, such as start-up parameters, structure feedstock, inoculation, composition cultures used. purpose this contribution is review recent developments in procedures involving different farm combined strategies. To evaluate effectiveness additives, results reported large number peer-reviewed articles were compared terms process parameters (i.e., temperature, organic carbon nitrogen contents, rate lignocellulose fractions, etc.) compost characteristics (humification, C/N ratio, macronutrient content, germination index). Most studies confirmed that use amendments an efficient way facilitate biodegradation improve sustainable management wastes. Overall, paper provides insights into techniques, identifies limitations current challenges co-composting, especially recommends areas for further research field.
