But compounds extracted from fly larva fat may prove to be a more environmentally friendly option, because antibiotic insecticides are not only expensive, but their introduction into the environment can lead to the development of antibiotic resistant bacteria. Inspired by previous studies, scientists at the Moscow Institute of physics and technology have turned their attention to the larvae of the black soldier fly as a substitute. The larvae, which are rich in fat and protein, are readily available because they are commercially raised as feed for fish and other livestock. < / P > < p > the researchers first collected fat from the larvae and squeezed them under a press. Then the key fatty acids were extracted from the fat with an organic solvent composed of water, methanol and hydrochloric acid. < / P > < p > & quot; the resulting extract – known as AWme [acidified water methanol extract] – has antibacterial properties, said Dr. Elena marusich, chief scientist of & quot. &We have shown that it is more effective than antibiotics, so it can almost replace antibiotics in agriculture against plant pathogens. &More specifically, dish tests have shown that AWme is very effective in killing five pathogenic strains of known infected plants. And as an added bonus, it is said that the extract can be refrigerated for a long time without losing its antibacterial activity. Global Tech
