Abstract Advances in science and technology have resulted the rapid development of modern society, which is clearly unsustainable because strain it places on current resources. The energy materials needed to sustain present society are derived primarily from non‐renewable fossil resources, will be depleted at some point. Plastics one example an important commodity lifestyle. While plastics undoubtedly superior terms their costs, processability functional properties, they currently resources...
The deleterious environmental impacts caused by plastic wastes have attracted worldwide concern.The biobased and biodegradable polyhydroxyalkanoate (PHA) appears to be one of the potential candidates replace some conventional plastics.However, high production cost PHAs has limited their market penetration.The major absorbing factors are upstream fermentation processes downstream PHA recovery technologies.The latter significantly affects overall process economics.Various technologies been...
Petroleum polymers contribute to non-degradable waste materials and it would therefore be desirable produce ecofriendly degradable materials. Biodegradation of polyhydroxybutyrate (PHB) in the presence oligomer hydrolase PHB depolymerase gave 3-hydroxybutyric acid which could oxidized acetyl acetate. Several bacteria fungi can degrade soil. showed a significant decrease molecular weight (Mw), number-average (Mn) dispersity (Mw/Mn) for all film formulations. Nanofibers its composites faster...
Abstract Poly-β-hydroxybutyrate (PHB) is a biodegradable polymer, synthesized as carbon and energy reserve by bacteria archaea. To the best of our knowledge, this first report on PHB production rare actinomycete species, Rhodococcus pyridinivorans BSRT1-1. Response surface methodology (RSM) employing central composite design, was applied to enhance in flask scale. A maximum yield 3.6 ± 0.5 g/L biomass 43.1 wt% dry cell weight (DCW) were obtained when using RSM optimized medium, which...
Spider silks are among the toughest known materials and thus provide models for renewable, biodegradable, sustainable biopolymers. However, entirety of their diversity still remains elusive, that exceed performance limits industrial fibers constantly being found. We obtained transcriptome assemblies from 1098 species spiders to comprehensively catalog silk gene sequences measured mechanical, thermal, structural, hydration properties dragline 446 species. The combination these protein...
Electronic trash, often known as E-waste, is a type of garbage generated by electronic in the industrial world, trash one most difficult and rapidly expanding issues. E-waste made up old or end-of-life appliances such computers, laptops, televisions, generators, DVDs, mobile phones, freezers, other items that are typically discarded their original owners due to short lifespan. It contains number hazardous constituents have negative impact on environment and, more importantly, human health if...
A 14-week feeding trial was conducted to determine the effects of dietary organic acids. The experimental diets were added with 0, 1, 2 or 3 g kg−1 a novel acid blend potassium diformate and fed triplicate groups red hybrid tilapia (Oreochromis sp.). Upon completion, challenged by immersion Streptococcus agalactiae. There no significant difference (P>0.05) in growth, feed utilization nutrient digestibility among treatment despite trend towards improved results fish acid-supplemented diets....
To develop a new easy and quick gene delivery system for any types of plants, we prepared ionic complexes plasmid DNA with designed peptide carriers, each which combined cell-penetrating (Bp100 or Tat(2)) polycation (nona-arginine copolymer histidine lysine). The present via the peptides demonstrated rapid efficient transient transfections into intact leaf cells Nicotiana benthamiana Arabidopsis thaliana without protoplast preparations. significantly higher transfection efficiency in...
Polyhydroxyalkanoate (PHA) is a promising candidate for use as an alternative bioplastic to replace petroleum-based plastics. Our understanding of PHA synthase PhaC poor due the paucity available three-dimensional structural information. Here we present high-resolution crystal structure catalytic domain from Chromobacterium sp. USM2, Cs -CAT. The shows that -CAT forms α/β hydrolase fold comprising core and CAP subdomains. active site containing Cys291, Asp447 His477 located at bottom cavity,...
Abstract BACKGROUND Rice husks ( RH ) are agricultural residues with abundant storage of cellulose and hemicellulose, making them a potential feedstock for polyhydroxyalkanoate PHA production. In this study, optimization pretreatment alkali under various conditions was performed before enzymatic hydrolysis using Celluclast 1.5 L EC 3.2.1.4) Novozyme 188 3.2.1.21). The hydrolysate fed to two strains, Burkholderia cepacia USM JCM 15050) Cupriavidus necator NSDG‐GG , an engineered strain H16...
