Batch ethanol fermentations from sweet sorghum juice by Saccharomyces cerevisiae NP 01 were carried out in a 500 ml air-locked Erlenmeyer flask under very high gravity (VHG) and static conditions. The maximum ethanol production efficiency was obtained when 9 g l of yeast extract was supplemented to the juice. The ethanol concentration (P), productivity (Qp) and yield (Yp/s) were 120.24 ± 1.35 g...

variability of tidal volume and respiratory rate in normally breathing man has long been demonstrated [1]. however because of lack of knowledge and technology primary ventilators could only deliver a fixed tidal volume in a fixed rate the so called volume controlled ventilation (vcv). vcv was volume preset time triggered and cycled and there was no synchronization with patient’s breaths. at tha...

abstract background: different modes of mechanical ventilation are used for respiratory support after coronary artery bypass graft (cabg). this study aimed to compare the effect(s) of using adaptive support ventilation (asv) and synchronized intermittent mandatory ventilation (simv) on the length of mechanical ventilation (intubation duration) and hospital stay after coronary artery bypass graf...

Fortifying any Linux server is significant to safeguard the user information, highbrow chattels, and stretch, commencing from hackers. The coordination supervisor in authority for safekeeping packet. Underneath maximum system formations, operator appellations, open sesame, FTP / tel-net r-sh guidelines relocated documentations be able seized by everyone programmed identical environment.

We constructed a bifunctional fusion protein for FADH2 regeneration and successfully coexpressed it with different flavin-dependent halogenases, as well dioxygenase that converts 6-chlorotryptophan to 4-Cl-Kynurenine. The figure is still life of laboratory bench, single oversized E. coli bacterium hovering over an Erlenmeyer flask. Cell disruption depicted in visual analogy cracking egg the lys...

A new memberof the anthramycin group of antibiotics1"'115, sibanomicin has been found in the culture filtrate of Micromonospora sp. SF2364. The antibiotic exhibited a marked antitumor activity in mice bearing leukemia P388 cells and a weak activity against Grampositive bacteria. In this communication, the production, isolation, characterization, structural elucidation and biological properties ...
