A new species of darkling beetle larvae that degrade plastic

Science Daily  July 20, 2020 Researchers in South Korea found that the larvae of a darkling beetle P. davidis indigenous to East Asia, including the Korean peninsula, can consume polystyrene and reduce both its mass and molecular weight. They confirmed that the proportion of Serratia bacillus in the intestinal tract of P. davidis larvae was responsible for six-fold increase in biodegradation. It was found that the gut flora of this larvae consisted of a very simple group of bacterial species unlike the gut flora of other conventional polystyrene-degrading insects. According to the researchers if we replicate the simple gut floral […]
