Summary: Lipstatin, a natural inhibitor of pancreatic lipase, produced by Streptomyces toxytricini, has been used as an anti-obesity drug. Chemical mutagenesis using N-methyl-N '-nitro-N-nitrosoguanidine (NTG) was performed to improve the strain for higher lipstatin yield. The bioreactor study showed that the NTG mutation significantly increased the lipstatin production from 2.4 g/L to 5.35 g/L, but resulted in lower Dry Cell Weight (DCW) and noticeable morphological differences.

Summary: The solubilization capacity of sustainable phenylalanine-derived surface-active ionic liquids (SAILs) towards polycyclic aromatic hydrocarbons (PAHs) was evaluated and compared with a conventional cationic surfactant, CTABr. The SAILs showed increased solubilization capacity with longer alkyl chain length, comparable to CTABr for certain SAIL types. The phenylalanine-derived SAILs also had the advantage of enzymatically cleaving ester and amide bonds under mild conditions for in situ separation of PAHs.

Summary: Over the past century, the accumulation of microplastics has become a significant threat to the environment, plants, microorganisms, and even humans. These microplastics can be intentionally produced for industries like cosmetics or unintentionally generated from the degradation of plastic debris. Inadequate management of plastic waste is a major contributor to the presence of microplastics. Ingesting microplastics can have various negative impacts on living organisms, but current strategies for their elimination and degradation are not effective. Green innovative technologies and further research are necessary for achieving a microplastic-free environment.
