FTIR Analysis of Biodegradation of Polystyrene by Intestinal Bacteria Isolated from Zophobas Morio and Tenebrio Molitor
AI summary Read the abstract
Researchers used FTIR analysis to confirm that gut bacteria isolated from mealworm and superworm beetles degrade polystyrene plastic. The study speeds up verification of polystyrene biodegradation from months to a shorter time frame, advancing the case for insect gut microbes as plastic-degrading agents.
Since the 1970s, polystyrene (PS) plastic marine pollution has become a global concern. Tenebrio molitor and Zophobas morio beetle larva actively respond to a diet of primarily polystyrene. The tantalizing evidence indicates that the gut bacteria of these beetle larva enables them not only to consume polystyrene, but to successfully biodegrade polystyrene. Heretofore, data collection to verify polystyrene degradation by the gut bacteria of these larva has taken up to six months per test. Our laboratory created a platform by dissolving PS into a liquid mineral culture medium to examine PS degradation by the gut bacteria. Under investigation, PS works as main carbon source supporting the growth of gut bacteria. Fourier-transform Infrared spectroscopy (FTIR) is an effective method which can provide relevant information on chemical changes. This study presents a methodology using FTIR and Visible Light Spectrometry as an efficient methodology to verify the physiological degradation of polystyrene.

Researchers tested the ability of mealworm (Tenebrio molitor) and superworm (Zophobas morio) larvae to biodegrade polystyrene foam through feeding experiments with different dietary conditions. They found that both species could consume and break down polystyrene, with gut microorganisms playing a key role in the degradation process. The study suggests that insect-based biodegradation could offer a biological approach to addressing polystyrene waste in the environment.
