Plastic has an extended lifespan in the environment, hence presenting enduring hazard to both humans and diverse organisms, particularly those inhabiting terrestrial aquatic ecosystems. Conventional techniques for breaking down waste made of plastic, such as dumping it landfills using chemical procedures, have been proven be disadvantageous a substantial detrimental impact on environmental sustainability. Plastics exhibit high resistance decomposition when left their own devices. Polymer degradation by insects currently no practical applicability. The concept degrading plastics is widely recognized, although precise manner which occurs remains incompletely understood. Moreover, advantages utilizing insect larvae involve low expenses absence secondary pollution. current review offers extensive overview latest research papers from 2016 2022 that specifically explore disintegration plastic microorganisms. aim this provide insight into processes involved microorganisms, while also emphasizing advanced viewpoints possible uses biodegradation, well challenges future prospects field.

Abstract Insects damaging and penetrating plastic packaged materials has been reported since the 1950s. Radical innovation breakthroughs of biodegradation have initiated discovery plastics by Tenebrio molitor larvae in 2015 followed Galleria mellonella 2017. Here we review updated studies on insect-mediated plastics. Plastic insect larvae, mainly some species darkling beetles (Tenebrionidae) pyralid moths (Pyralidae) is currently a highly active potentially transformative area research. Over past eight years, publications increased explosively, including discoveries ability different to biodegrade plastics, performance, contribution host microbiomes, impacts polymer types their physic-chemical properties, responsible enzymes secreted gut microbes. To date, almost all major polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), terephthalate (PET), polyurethane (PUR), polystyrene (PS) can be biodegraded T. ten other representing Tenebrionidae Pyralidae families.

Mismanaged plastics, upon entering the environment, undergo degradation through physicochemical and/or biological processes. This process often results in formation of microplastics (MPs), most prevalent form plastic debris (<1 mm). MPs pose severe threats to aquatic and terrestrial ecosystems, necessitating innovative strategies for effective remediation. Some photosynthetic microorganisms can degrade but there lacks a comprehensive review. Here we examine specific role photoautotrophic water soil environments biodegradation focussing on their unique ability grow persistently diverse polymers under sunlight. Notably, these cells utilise light CO2 produce valuable compounds such as carbohydrates, lipids, proteins, showcasing multifaceted environmental benefits. We address key scientific questions surrounding utilisation nanoplastics (NPs) bioremediation, discussing potential engineering enhanced efficacy. Our review highlights significance alternative biomaterials exploration strains expressing enzymes, polyethylene terephthalate (PET) hydrolases, conjunction with microalgal cyanobacterial metabolisms. Furthermore, delve into promising photo-biocatalytic approaches, emphasising coupling sunlight exposure. The integration microalgal-bacterial consortia is explored biotechnological applications against NPs pollution, synergistic effects wastewater treatment absorption nitrogen, heavy metals, phosphorous, carbon. In conclusion, this provides overview current state research use bioremediation. It underscores need continued investigation development approaches tackle global issue pollution ecosystems.

Cancer is a leading cause of death worldwide, characterized by uncontrolled cell growth and multiple mutations. Chemotherapy often associated with harmful side effects, cancer cells may become resistant through various mechanisms. New approaches, which are able to address both the toxicity resistance issues chemotherapy, primary importance in research. Antimicrobial peptides (AMPs), naturally occurring molecules innate immune system all living organisms, have wide spectrum cytotoxic activities against could be promising alternative actual chemotherapeutics. Here, we tested peptide fractions, rich AMPs, extracted from hemolymph larvae insect Hermetia illucens on HT29 HCT116 human colorectal cells, observing inhibition accumulation G2/M phase increased apoptosis. Furthermore, extract induced significant cytoskeleton reorganization, resulting reduced motility. These effects were more evident fractions obtained Escherichia coli-infected larvae.

Abstract The ubiquitous incorporation of plastics into daily life, coupled with inefficient recycling practices, has resulted in the accumulation millions metric tons plastic waste, that poses a serious threat to Earth's sustainability. Plastic pollution, global problem, disrupts ecological balance and endangers various life forms. Efforts combat pollution are underway, promising avenue being biological degradation facilitated by certain insects their symbiotic gut microorganisms, particularly bacteria. This review consolidates existing knowledge on influence microbiota. Additionally, it delves potential mechanisms employed symbiosis bacteria, exploring bioconversion waste value‐added biodegradable polymers through mineralization. These insights hold significant promise for bio‐upcycling opening new horizons future biomanufacturing high‐value chemicals from plastic‐derived compounds. Finally, we weigh pros cons research endeavors related bioprospection plastic‐degrading bacteria underexplored insect species. We also underscore importance bioengineering depolymerases novel characteristics, aiming application remediation valorization plastics.
