Optimization and production of laccase enzyme by Bacillus cereus isolated from effluent of paint producing industry

Bulletin of the National Research Centre/Bulletin of the National Research Center, Journal Year: 2025, Volume and Issue: 49(1)

Published: April 22, 2025

Abstract Background Paint industry uses different coloured pigment that are known to contain heavy metals including titanium dioxide, iron oxides, aluminium, mica flakes, cadmium, mercury and lead. Laccase enzyme has been reported have the ability degrade used in industries. is associated with a wide class of enzymes called polyphenol oxidases which useful industries such as wine beverage, baking, textile, printing tannery pharmaceutical. Microorganisms produce laccase for bioremediation. This study aimed at isolating bacteria from waste water paint industry, screening potential producing production enzyme. Methodology Bacteria were isolated effluent screened using 0.04% guaiacol. highest activity optimization studies temperature, pH, inoculum volume, substrate concentration copper sulphate concentration. Duncan multiple range test was utilized separate means after experiments conducted triplicate. Data analysed Statistical Package Social Sciences. Results Different but Bacillus cereus had primary secondary screening. Optimization growth parameters showed B. 0.0489 U/mL highest. Synthesis optimum 5 days, pH 6.0, 35 °C 5% mM guaiacol 0.3 sulphate. Conclusion study’s findings demonstrated found these can effectively be employed bioremediation soil contaminated by present effluents thereby preventing environmental pollution.

Concepts and criteria defining emerging microbiome applications

Microbial Biotechnology, Journal Year: 2024, Volume and Issue: 17(9)

Published: Sept. 1, 2024

Abstract In recent years, microbiomes and their potential applications for human, animal or plant health, food production environmental management came into the spotlight of major national international policies strategies. This has been accompanied by substantial R&D investments in both public private sectors, with an increasing number products entering market. Despite widespread agreement on uses across disciplines, stakeholders countries, there is no consensus what defines a microbiome application. often results non‐comprehensive communication insufficient documentation making commercialisation acceptance novel challenging. To showcase complexity this issue we discuss two selected, well‐established propose criteria defining application conditions use clear communication, facilitating suitable regulatory frameworks building trust among stakeholders.

Enhanced chaotrope tolerance and (S)‐2‐hydroxypropiophenone production by recombinant Pseudomonas putida engineered with Pprl from Deinococcus radiodurans

Microbial Biotechnology, Journal Year: 2024, Volume and Issue: 17(3)

Published: March 1, 2024

Pseudomonas putida is a soil bacterium with multiple uses in fermentation and biotransformation processes. P. ATCC 12633 can biotransform benzaldehyde other aldehydes into valuable α-hydroxyketones, such as (S)-2-hydroxypropiophenone. However, poor tolerance of this strain toward chaotropic hampers efficient To circumvent problem, we expressed the gene encoding global regulator PprI from Deinococcus radiodurans, an inducer pleiotropic proteins promoting DNA repair, putida. Fine-tuned expression was achieved using plasmid under control LacI

Mineralization of Ni2+-Bearing Mn Oxide through Simultaneous Sequestration of Ni2+ and Mn2+ by Enzymatically Active Fungal Mn Oxides

Minerals, Journal Year: 2024, Volume and Issue: 14(4), P. 330 - 330

Published: March 23, 2024

A fungus, Acremonium strictum KR21-2, produces biogenic manganese oxides (BMOs) that can oxidize exogenous Mn2+ ions to form different BMO phases. When other guest are present during the formation, it strongly affect mineralogical characteristics of resultant phase. The impact coexisting Ni2+ on mineralogy phases formed through enzymatic Mn(II) oxidation and its sequestration ability is not yet fully understood. To better understand it, repeated experiments were conducted using BMOs in Ni2+/Mn2+ binary, single Ni2, solution systems with a pH range 6.0 7.5. It was observed simultaneous efficient, irreversible incorporation at values above 7.0. showed Ni2+-bearing Mn resembling feitknechitite (β-MnOOH) developed oxidation. At below 6.5, turbostratic birnessite structure maintained even binary solutions, subsequently, efficiency low. pseudo-first-order rate constants enzymatically inactivated for two orders magnitude lower than those active BMOs, indicating crucial role enzymes precipitating oxide These findings provide new insights into mechanism interaction microbial activity under circumneutral conditions.

Biodecolorization of Reactive Red 120 Azo Dye by Metal-Ion Tolerant Lysinibacilluscapsici PB300 (T) Bacteria Bacteria and its Application Potential in Textile Effluents Treatment

Published: April 25, 2024

Currently, the textile industry is among most rapidly expanding areas of economy and an important source water pollution. There are many efficient chemical physical methods for treating effluent, but they produce secondary pollutants. Therefore, there a need to manage waste wastewater. The potential EPS-producing plant growth-promoting rhizobacteria Lysinibacillus capsici PB300 (T) bacteria strain has been isolated from bark borer-affected Peltophorum pterocarpum determined be effective in > 95 decolorizing Reactive Red 120, other azo dyes such as AB11385%, orange II 94.62%, Congo red phenol 94.54%, mixtures 81.66%. Physico-chemical factors were optimized manually, including Taguchi design. EPS production, PGPR strain, fabric discoloration L. qualitatively studied. FTIR, GC-MS, UV absorbance studies also confirmed that dye had broken into its amines. Research findings using enzyme assays have shown can utilize laccase manganese peroxidase capable degrading significantly. According this work, immobilised cells studied four bacterial consortiums, (T), Alcaligenes faecalis subsp. Phenolicus DSM 16503 Acinetobacterbaumanni ATCC 19606 Pseudomonasaeruginosa JCM 5962 may employed degrade RR120 effectively, it concluded significantly effluent treatment.
