Bioconversion of organic waste by insects – A comprehensive review

Process Safety and Environmental Protection, Journal Year: 2024, Volume and Issue: 187, P. 1 - 25

Published: April 28, 2024

The ever-growing human population has forced people to intensify agriculture meet the demand for food and feed. However, increase in global agricultural production also means an waste generation, which is mostly improperly managed, especially low- middle-income countries where adequate management infrastructure limited inefficient. Consequently, organic become a burden due its negative impact on environment health. In this sense, insect-based bioconversion could be economically viable, environmentally friendly, technically feasible approach management. Based review, wastes from agriculture, industry, household, municipalities, starch industry are considered as suitable substrates bioconverter insects. Commonly used insects include cricket, yellow mealworm, superworm, black soldier fly, house flesh fly blow fly. Rearing facilities must adapted provide optimal environmental conditions growth development of reared insect maximize rate efficiency. Bioconverter their by-products can industrially processed into animal feed, fertilizer biodiesel or extracted isolate bioactive compounds. challenges associated with social acceptance, method-, infrastructure- technology-related problems, availability substrates, political legal regulations. summary, potential reduce waste, create jobs, novel products, offer sustainable source protein feed world's growing population.

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.

Gastric cancer (GC) is one of the leading causes cancer-related mortality worldwide, characterised by poor prognosis and limited responsiveness to chemotherapy. There a need for new more effective anticancer agents. Antimicrobial peptides (AMPs) represent promising class biomolecules this purpose. Naturally occurring in innate immune system, these can also exert cytotoxic effects against cells, earning them designation "anticancer peptides" (ACPs). They have potential be viable support current chemotherapy schedules due their selectivity cells minor propensity induce chemoresistance cells. Insects are an excellent source AMPs. Among them, its ability thrive hostile microorganism-rich environments, we isolated peptide fraction from Hermetia illucens L. (Diptera: Stratiomyidae) haemolymph evaluate possible activity.
