Four spontaneously derived serologically distinct classes of mutants of the Paramecium bursaria chlorella virus (PBCV-1) were isolated using polyclonal antiserum prepared against either intact PBCV-1 or PBCV-1-derived serotypes. The oligosaccharide(s) of the viral major capsid protein and two minor glycoproteins determined virus serological specificity.(More)
The presence of acetate exceeding 5 g/L is a major concern during E. coli fermentation due to its inhibitory effect on cell growth, thereby limiting high-density cell culture and recombinant protein production. Hence, engineered E. coli strains with enhanced acetate tolerance would be valuable for these bioprocesses. In this work, the acetate tolerance of(More)
Chlorella virus PBCV-1 particles contain three glycoproteins, the major capsid protein Vp54 and two minor proteins Vp280 and Vp260. The major capsid protein is myristylated as well as glycosylated. Both modifications are in the carboxyl-terminal portion of the protein. A gene which is modified in a PBCV-1 antiserum-resistant mutant was cloned and sequenced.(More)
A major challenge in bioethanol fermentation is the low tolerance of the microbial host towards the end product bioethanol. Here we report to improve the ethanol tolerance of E. coli from the transcriptional level by engineering its global transcription factor cAMP receptor protein (CRP), which is known to regulate over 400 genes in E. coli. Three ethanol(More)
The use of a dual mobile and large screen approach offers a number of intriguing possibilities including a potential solution to the problem of managing conflicts that arise when a large screen is shared in a public setting. Here, we report on a series of experiments carried out to determine quantitative or qualitative effects of user performance when(More)

In order to investigate the immunological damage in rat immunized with AT1-receptor peptide, 18 male Wistar rats were divided into two groups: immunized-group (n = 12), each rat was immunized with 150 micrograms AT1-receptor peptide coupled to bovine serum albumin, together with Freund's adjuvant. Control group (n = 6), sham-immunized, "immunized liquid"(More)
