However, despite advances in microbial production of bioplastics, significant challenges remain in achieving high conversion efficiency and scalability for industrial applications. This study is the first to report the synthesis of a 100% bio-based polyester using both 1,12-dodecanedioic acid (1,12-diacid) and 1,12-dodecanediol (1,12-diol) via a two-step microbial bioconversion from a single plant oil-derived alkane. An engineered <em>Candida tropicalis</em> strain produced 150 g/L of 1,12-diacid with a productivity of 1.53 g/(L·h) in a 5 L fed-batch system using a two-phase biotransformation strategy. <em>Escherichia coli</em> engineered to express carboxylic acid reductase, which reduces carboxylic acids to aldehydes, and its activation enzyme phosphopantetheinyl transferase, converted 1,12-diacid into 68 g/L 1,12-diol with a productivity of 1.42 g/(L·h) in a 5 L fed-batch system, representing high titer and productivity for microbial production of long-chain α,ω-diols. Both monomer production processes were successfully scaled up to a 50 L pilot fermenter, validating their potential for industrial implementation. A highly efficient downstream purification process was developed, achieving &gt; 98% purity and recovery rates for both monomers. The bio-derived monomers enabled the synthesis of polyesters with molecular weight and thermal characteristics similar to petroleum-based monomers of the same chemical structure.

Employing a multiscale characterization and Random Forest (RF) modeling, we evaluated the impacts of temperature and humidity fluctuations on the bamboo quality, and the influence mechanism of storage conditions on its physical and mechanical properties were elucidated. Results indicated that elevated temperature and humidity led to remarkable fluctuation in bamboo moisture (from −20.36% to 32.99%), weight gain (from −32.69% to 6.19%), and dimensional expansion (from −5.37% to 2.38%).

Systematic characterization revealed that the sodium alginate mixed with 30% that mass of phosphorylated chitosan (SA-30 PCS) exhibits exceptional fire safety performance, achieving a limiting oxygen index (LOI) of 33.7% and a V-0 rating in the vertical burning test (Underwriters Laboratories Standard 94), which indicates the highest level of flame resistance.

A sustainable hydrophobic modification strategy employing methyltrichlorosilane vapor deposition further endowed the aerogel with moisture resistance. As a wholly biomass-derived system (SA/PCS), the aerogel eliminates persistent toxic residues associated with halogenated flame retardants, while its phosphorus components are covalently bonded in polymeric chains, significantly reducing environmental mobility compared to inorganic phosphates.

The combination of CPI and CNF at a ratio of 20꞉1 (<em>w/w</em>) exhibited the highest encapsulation efficiency (70.90% ± 1.66%) and sustained release properties during in vitro digestion, thereby enhancing CAP bioaccessibility from 39.40% ± 2.33% to 81.54% ± 1.95%.

Comprehensive characterization revealed that the incorporation of CNF significantly improved the colloidal properties of the emulsion, including its rheological behavior and thermal stability. Mechanistic investigations demonstrated that the enhanced encapsulation capability was attributed to the formation of stable hydrogen-bonding networks between CNF and CPI. Moreover, CAP is bound with CPI through synergistic hydrogen bonding and van der Waals interactions, with Arginine-179 identified as the key residue for binding (binding free energy:10.46 kJ/mol).

To overcome these challenges, we developed an innovative approach involving the treatment of lyocell fibers with a cationic modifier (CM), poly(diallyldimethylammonium chloride), followed by the application of anionic polyacrylic acid emulsions (AEs). The effects of AE concentration, curing temperature, and curing time on anti-fibrillation performance were systematically evaluated.

Upon curing, a discontinuous film formed on the fiber surface, which hindered water penetration and enhanced lateral cohesion between microfibrils under wet conditions. As a result, the modified fabrics exhibited markedly improved anti-fibrillation performance without compromising mechanical properties or whiteness. Furthermore, the air permeability of wet fabrics increased by 46.4%, and dyeing properties and glossiness were markedly enhanced.
