Zymomonas mobilis is an alcohol-tolerant microorganism which is potentially useful for the commercial production of ethanol. This organism was found to contain cardiolipin, phosphatidylethanolamine, phosphatidylglycerol, and phosphatidylcholine as major phospholipids. Vaccenic acid was the most abundant fatty acid, with lesser amounts of myristic, palmitic,(More)
Protein synthesis is severely depressed in hibernating mammals. In the absence of significant protein synthesis, the continued turnover of proteins as a function of normal cellular activity would result in the net depletion of protein pools. We measured levels of ubiquitylated proteins in the gut of thirteen-lined ground squirrels ( Spermophilus(More)
The potential utility of Zymomonas mobilis as an organism for the commercial production of ethanol would be greatly enhanced by the addition of foreign genes which expand its range of fermentable substrates. We tested various plasmids and mobilizing factors for their ability to act as vectors and introduce foreign genes into Z. mobilis CP4. Plasmid(More)
The cryptic plasmid pRUT41 from Zymomonas mobilis was examined for its biological properties. This plasmid was found to be conjugally transferred from Z. mobilis CP4 to Escherichia coli BM21 and to carry genes for antibiotic resistance (gentamicin, kanamycin, and streptomycin). Covalently closed circular plasmid DNA was isolated from eight transconjugants(More)
We have examined the relationship between membrane fluidity and the alcohol-induced loss of righting reflex at different temperatures using the fish Gambusia affinis. The potency of ethanol and hexanol increased dramatically with temperature. Ethanol-induced narcosis could be antagonized by a reduction in incubation temperature. Both an increase in(More)
