Summary: The accumulation of plastics poses a worldwide environmental risk. Polyethylene terephthalate (PET) degrades slowly and produces hazardous substances, highlighting the need to eliminate plastic waste from the environment. This study focuses on the potential of naturally occurring microbial strains isolated from plastic waste dumping sites to degrade PET. The results show that a microbial consortium (S. aurantiaca + B. subtilis + A. flavus + A. niger) can effectively degrade PET, indicating its potential to eliminate PET in plastic contaminated sites without health or environmental risks.

Summary: Two efficient feather-degrading bacteria, Bacillus sonorensis and Bacillus licheniformis, were isolated from honeybee samples and showed the ability to grow on chicken feathers as the sole carbon and nitrogen sources. B. licheniformis CG1 strain exhibited high keratinase activity and broad pH stability, making it advantageous for various industrial applications. Gene clusters associated with the synthesis of antimicrobial compounds were identified in most Bacillus isolates, with B. licheniformis CG1 containing sequences similar to lichenysin and lichenicidin, which have shown antimicrobial activity against different bacteria. This study highlights the potential of B. licheniformis CG1 for industrial applications such as animal nutrition, leather processing, detergent formulation, and feather degradation.

Summary: This study investigated the bacterial and fungal diversity during composting of textile waste, finding Proteobacteria, Bacteroidetes, and Actinobacteria to be dominant in the mesophilic phase but not in the thermophilic phase. Despite the sustained thermophilic profile of composting textile waste, fungi were observed during the thermophilic phase. Rozellomycota, Basidiomycota, and Ascomycota were the most dominant phyla during both composting phases, suggesting their potential for bioaugmentation to improve the maturity level of textile waste compost.

Summary: In-situ bioremediation of mangrove soil contaminated with PET and PS microplastics was investigated using indigenous microbial consortium capable of degrading the plastics. Results showed varied degrees of weight loss after 90 experimental days, with the treated plot recording 18% weight loss. Post bioremediation, soil concentrations of Si, S, and Fe increased while concentrations of C, O, Na, Mg, Al, Cl, and K decreased.

Summary: Fossil-fuel-based plastics have caused significant environmental issues, but some bacteria have the ability to degrade and metabolize them, suggesting the potential of biotechnologies based on plastic biodegradation. Polypropylene (PP), one of the most consumed plastics, is somewhat difficult to degrade under natural conditions, but scientists have made efforts in using other microbes and materials to enhance its biodegradation. Current methods such as gravimetric analysis and physical characterization are not sufficient to confirm the biodegradation of PP, so new techniques need to be explored. Further studies are also needed to investigate plastic-degrading microorganisms and improve enzymatic strategies.

Summary: This review discusses the strategies and recent advances in using microbial consortia to degrade complex compounds, including plastics, petroleum, antibiotics, azo dyes, and pollutants in sewage. It is shown that microbial consortia have advantages over isolated bacteria as they are more adaptable and stable, and can provide a suitable catalytic environment for each enzyme. The development of synthetic biology and gene-editing tools allows the design of artificial microbial consortia systems that are more efficient, stable, and robust.

Summary: Wastewater produced by textile industries is difficult to treat due to its large volume, toxicity, and variable composition. In this comprehensive study, two native bacterial consortia were found to degrade pure textile effluent without pre-treatment or the addition of nutritional sources, reducing TOC, COD, and pH. One consortium was more efficient in decolorization and COD reduction, while the other showed better performance in reducing toxicity. Diversity analysis revealed no significant loss of diversity during degradation.

Summary: This study focused on the overexpression of a keratinase gene in Bacillus subtilis to enhance the degradation of chicken feathers. The recombinant strain showed increased activity of disulfide reductase and keratinase, resulting in the rapid degradation of feathers and accumulation of free amino acids. Structural characterizations confirmed the breakdown of feather microstructure and polypeptide bonds by the recombinant strain. This study provides new insights into the mechanism of keratin degradation and offers a potential recombinant strain for the valorization of keratin wastes.

Summary: This study verified the accelerated biodegradation of nonwovens in cultivated soil with the addition of poultry feathers. The presence of waste rich in keratin positively influenced the biodegradation time of the tested materials. The investigation on ecotoxicity showed no negative effects on microbiological activity. The determination of carbon to nitrogen ratio indicated an increased nutrient content with feather addition. This research is important for managing poultry feather waste in agriculture and provides an environmentally safe alternative.

Summary: This review introduces the techniques and mechanisms of bacteria immobilization on biochar, as well as its applications in bioremediation and agriculture. The immobilization characteristics of biochar depend on pyrolysis methods, raw materials, and properties of biochar. Scanning electron microscope and colony forming unit analysis are commonly used to verify the immobilization efficiency. Applying biochar-immobilized bacteria can improve soil quality, plant growth, and crop yield.
