The production of acetone, butanol, and ethanol (ABE) by fermentation is a process that had been used by industries for decades. Two stage immobilized column reactor system integrated with liquid-liquid extraction was used with immobilized Clostridium acetobutylicum DSM 792, to enhance the ABE productivity and yield. The sugar mixture (glucose, mannose, galactose, arabinose, and xylose) represe...

The performance of the Etest and agar dilution for in vitro antimicrobial susceptibility of Campylobacter spp. was evaluated using a quality control strain Campylobactor jejuni ATCC 33560, and 81 C. jejuni and 54 Campylobacter coli isolates recovered from retail raw meats. Seven antimicrobial agents: chloramphenicol, ciprofloxacin, doxycycline, erythromycin, gentamicin, nalidixic acid and tetra...

Trickle bed reactor was used to study the hydrogenation of nitrobenzene over Ni/SiO2 catalyst. The catalyst prepared using Highly Dispersed Catalyst (HDC) technique. Porous silica particles (capped cylinders, 6x5.5 mm) were as support. characterized by TPR, BET surface area and pore volume, X-ray diffraction, Raman Spectra. trickle packed with diluted fine glass beads in order decrease external...

Radioactive tubulin subunit incorporation into porcine and dogfish shark brain microtubules which are at steady state has been found to result primarily from a diffusional reaction, in which subunits are incorporated although there are an equal number of tubulin subunit additions to and losses from each of the two microtubule ends in a unit of time. Treadmilling is very inefficient, and the Weg...
