Bacteria infection is a growing problem all over the world. Within this contribution, phosphonium-phosphonic acid or hexyl pyridinium-phosphonic acid bearing copolymer series derived via ring opening metathesis polymerization (ROMP) method are synthesized to investigate their biocidal activity on the glass surface. The presence of phosphonic acid moieties enhanced the coating capability on the iron oxide nanoparticles and the thermal properties of the copolymers. Biocidal activities of the polymers and iron oxide bearing polymers were tested against E.coli and S.aureus. Polymers possessing higher activity was then blended with commercial polyacrylonitrile for the nanofiber formation via electrospinning methods.

In Asia, uneaten cooked rice is the highest portion amongst many forms of food wastes that are thrown away. In order to make use of the thrown-away rice and potentially use it for liquid fuels, steamed Japanese rice was evaluated on biobutanol production through a two-step fermentation by amylase-producing Aspergillus oryzae, and solvent-producing Clostridium acetobutylicum YM1. The effects of sterilization and providing anaerobic conditions on solvent production in acetone-butanol-ethanol (ABE) fermentation cannot be underestimated. Several conditions, including aerobic, anaerobic, sterile, and non-sterile were investigated concerning the solvent production capability of Clostridium acetobutylicum YM1. The maximum solvent production was 11.02 ± 0.22 g/l butanol and 18.03 ± 0.34 g/l total ABE from 75 g/l dried rice. The results confirmed that the solvent production performance of the YM1 strain was not affected by the sterilization conditions. In particular, 10.91 ± 0.16 g/l butanol and 16.68 ± 0.22 g/l ABE were produced under non-sterile and aerobic conditions, which can reduce industrial-scale production costs.

... It can also be produced from whey. 23 The conversion of whey to bioethanol involves lactose hydrolysis, fermentation of sugars such as glucose, fructose, and sucrose into ethanol and carbon dioxide, and downstream processing to achieve the desired ethanol purity. 24 Fermentable sugars are typically obtained through enzymatic or microbial hydrolysis and then converted by ethanol-producing microorganisms, such as Saccharomyces cerevisiae and Candida spp., under anaerobic conditions. ...
