Enhancing cellulose acetate biodegradability in cigarette filters: an in-depth analysis of thermal alkaline pretreatment, microbial dynamics, and breakdown pathway prediction.

Background: The demand for bioplastics has increased exponentially as they have emerged as alternatives to petrochemical plastics. However, there is a substantial lack of knowledge regarding bioplastic degradation. This study developed a novel pretreatment method to improve the accessibility of a bioplastic substrate for biodegradation.

Complete genome sequence of sp. DP, a hydrogenotrophic and thermophilic methanogen.

Here, we report the complete genome sequence of the thermophilic hydrogenotrophic methanogen sp. DP isolated in South Korea from an anaerobic digester fed with cigarette waste. The genome consists of 1,693,285 bp, with 1,772 protein-coding genes and a GC content of 48.
