mathematical modeling and simulation of microbial polyhydroxybutyrate (phb) production process is beneficial for optimization, design, and control purposes. in this study a batch model developed by mulchandani et al., [1] was used to simulate the process in matlab environment. it was revealed that the kinetic model parameters were estimated off the optimal or at a local optimal point. therefore...

The beneficial health effects of cranberries have been attributed to their (poly)phenol content. Recent studies have investigated the absorption, metabolism and excretion of cranberry (poly)phenols; however, little is known about whether they follow a dose response in vivo at different levels of intake. An acute double-blind randomized controlled trial in 10 healthy men with cranberry juices co...

Abstract Microplastics (MP, plastic particles between 0.1 and 5000 ?m) contaminate agricultural soils through the application of organic fertilizers, sewage sludge, mulch. MP surfaces MP-soil interface provide specific habitats for soil microorganisms—the plastisphere. Microorganisms in plastisphere may benefit from utilizing as a carbon (C) source. Hydrolyzable with ester bonds are susceptible...

A macromonomer 5 consisting of a polymerizable vinylcyclopropane end group and a poly(N-isopropylacrylamide) (poly(NiPAAm)) chain was obtained from amidation of 1-ethoxycarbonyl-2-vinylcyclopropane-1-carboxylic acid (4) with an amino-terminated poly(NiPAAm) 3 as an example. This macromonomer 5 showed an LCST effect after complexation of the vinyl end group with ß-cyclodextrin in water. Via radi...

The term 'aramid fibre' refers to a manufactured fibre in which the fibre-forming substance is a long-chain synthetic polyamide with at least 85% of the amide linkages attached directly to two aromatic rings (Preston, 1978; Yang, 1993). 'para-Aramid fibres' are those in which the amide Iinkages are in the para (l,4) positions on the aromatic rings. para-Aramid fibres of poly(para-phenyleneterep...

This study analyses the possibility of reprocessing used poly(vinylidene fluoride), PVDF, maintaining the main properties critical for its use in piezoelectric sensor/actuator applications. The influence of multiple reprocessing cycles of PVDF on crystallinity and ß-phase content fundamental for its electroactive behaviour, was studied. Nine reprocessing cycles were completed and it was found t...

An experiment was conducted at the Indian Agricultural Research Institute, New Delhi (2017-18) to report identification of halophilic poly-ß-hydroxybutyrate (PHB) producing bacteria and optimization process parameters for maximum PHB recovery. The phylogenetic analysis classified isolates into bacterial phylum α, γ-Proteobacteria, Firmicutes. Halomonas sp. KB7 Stenotrophomonas maltophila B11 pr...

Abstract The effect of the biopreparation Rizotorfin and growth regulators Albit, Kornevin, Epin-Extra on symbiotic activity yield bean plant varieties Geliada Shokoladnitsa was studied under field conditions. nitrogenase increased in Heliada plants after treatment seeds with against increase bacteroides area, amount area volutin decrease poly-ß-oxybutyric acid (POM). protective evident variety...

BACKGROUND Pancreatic ductal adenocarcinomas (PDA) activate a glutamine-dependent pathway of cytosolic nicotinamide adenine dinucleotide phosphate (NADPH) production to maintain redox homeostasis and support proliferation. Enzymes involved in this pathway (GLS1 (mitochondrial glutaminase 1), GOT1 (cytoplasmic glutamate oxaloacetate transaminase 1), and GOT2 (mitochondrial glutamate oxaloacetate...
