In an effort to improve reactor performance and process operability, the microbial biotransformation of (-)-trans-carveol to (R)-(-)-carvone by hydrophobic Rhodococcus erythropolis DCL14 was carried out in a two phase partitioning bioreactor (TPPB) with solid polymer beads acting as the partitioning phase. Previous work had demonstrated that the substrate and product become inhibitory to the or...

Utilization of additives can be an effective way to improve the durability and performance HMA, making them more resistant Moisture deformation. Plus, they reduce need for maintenance repairs, saving you time money in long run. In this study, CKD was used place limestone as a filler asphalt mixture proportions 0%, 25%, 50%, 75%, 100%, polymer SBS 4%by weight asphalt. According findings, replace...

Flexible strain sensors have attracted extensive attention due to their potential applications in wearable electronics and health monitoring. However, it is still a challenge obtain flexible with both high stretchability wide linear sensing range. In this study, styrene-ethylene-butadiene-styrene copolymer/carbon nanotubes (SEBS/CNTs) composite fiber which showed electrical conductivity was fab...

A review study was conducted to examine the adverse effects of styrene, styrene mixtures, or styrene and/or styrene mixtures and noise on the auditory system in humans employed in occupational settings. The search included peer-reviewed articles published in English language involving human volunteers spanning a 25-year period (1990-2015). Studies included peer review journals, case-control stu...

Naphthalene dioxygenase (NDO) from Pseudomonas sp. strain NCIB 9816-4 adds both atoms of the dioxygen molecule to styrene to form (R)-l-phenyl-1,2-ethanediol. Product formation is tightly coupled to dioxygen consumption and NADH oxidation. NDO oxidizes styrene-d8 at almost the same initial rate as styrene. The results indicate that dioxygen activation by NDO is different from that by cytochrome...
