Enzymatic Synthesis of Biobased Polyesters and Polyamides
Nowadays, “green” is a hot topic almost everywhere, from retailers to universities to industries; and achieving a green status has become a universal aim. However, polymers are commonly considered not to be “green”, being associated with massive energy consumption and severe pollution problems (for example, the “Plastic Soup”) as a public stereotype. To achieve green polymers, three elements sh...
متن کاملMicrobial production of lactate-containing polyesters
Due to our increasing concerns on environmental problems and limited fossil resources, biobased production of chemicals and materials through biorefinery has been attracting much attention. Optimization of the metabolic performance of microorganisms, the key biocatalysts for the efficient production of the desired target bioproducts, has been achieved by metabolic engineering. Metabolic enginee...
متن کاملTwo-step biocatalytic route to biobased functional polyesters from omega-carboxy fatty acids and diols.
Biobased omega-carboxy fatty acid monomers 1,18-cis-9-octadecenedioic, 1,22-cis-9-docosenedioic, and 1,18-cis-9,10-epoxy-octadecanedioic acids were synthesized in high conversion yields from oleic, erucic and epoxy stearic acids by whole-cell biotransformations catalyzed by C. tropicalis ATCC20962. Maximum volumetric yields in shake-flasks were 17.3, 14.2, and 19.1 g/L after 48 h conversion for...
متن کاملStilbene-containing Thermotropic Liquid Crystalline Polyesters for Aerospace Applications
Materials used in space travel must maintain thermal and dimensional stability in extreme conditions, while remaining melt processable for ease of industrial production. The rigid chemical structure of stilbene often correlates to polymers exhibiting a liquid crystalline morphology and the olefinic bond undergoes a [2 + 2] cycloaddition in the presence of UV light. Based on the combined benefit...
متن کاملBiosynthesis and biodegradation of 3-hydroxypropionate-containing polyesters.
3-Hydroxypropionate (3HP) is an important compound in the chemical industry, and the polymerized 3HP can be used as a bioplastic. In this review, we focus on polyesters consisting of 3HP monomers, including the homopolyester poly(3-hydroxypropionate) and copolyesters poly(3-hydroxybutyrate-co-3-hydroxypropionate), poly(3-hydroxypropionate-co-3-hydroxybutyrate-co-3-hydroxyhexanoate-co-3-hydroxyo...
