Due to the intensifying climate crisis and other environmental problems caused by our heavy dependence on fossil resources, there has been much effort to establish biorefinery platforms for the bio-based production of chemicals from renewable resources. In particular, systems metabolic engineering has paved the way to efficiently engineer diverse microorganisms for the production of desired platform chemicals. In this paper, recent advances in the bio-based production of representative platform chemicals including diamines, dicarboxylic acids, diols, hydroxy acids, ω-amino acids, and lactams are reviewed with an accompanying table summarizing the titer, yield, and productivity achieved for each chemical. In addition, future prospects and challenges toward the successful industrialization of bio-based platform chemicals are discussed.

In this study, cobalt composite immobilized on polysulfone fibrous network nanoparticles (CCPSF NPs) were synthesized in a controllable and one-step way under microwave-assisted conditions. The structure of CCPSF NPs was characterized by SEM images (for morphology and size distribution), TGA (for thermal stability), BET technique (for the specific surface area), FT-IR spectroscopy (for relation group characterization), and XRD patterns (for crystal size). The oxidation of the primary and secondary alcohols to aldehyde and ketone was investigated using synthesized CCPSF NPs under solvent-free microwave-assisted conditions, and high oxidizing activity was observed. In addition to oxidation properties, the anticancer activity of the synthesized CCPSF NPs in breast cancer was evaluated by the MTT method , and significant results were obtained.
