Kerwar, Suresh S. (Oregon State University, Corvallis), Vernon, H. Cheldelin, and L. W. Parks. Valine-isoleucine metabolism in Acetobacter suboxydans and the inhibition of growth by valine. J. Bacteriol. 88:179-186. 1964.-Extracts of Acetobacter suboxydans can synthesize valine and isoleucine via acetolactate and acetohydroxybutyrate, respectively. The amounts of these amino acids synthesized f...

Acetobacter spp. are used for industrial vinegar production because of their high ability to oxidize ethanol to acetic acid and high resistance to acetic acid. Two-dimensional gel electrophoretic analysis of a soluble fraction of Acetobacter aceti revealed the presence of several proteins whose production was enhanced, to various extents, in response to acetic acid in the medium. A protein with...

An economical mass production system of bacterial cellulose (BC) on agitated culture was constructed. We frst conducted screening of BC producers in agitated culture. A total of 2096 strains were isolated from natural sources and the best BC producing strain, BPR2001, was selected. According to the taxonomic examination, we concluded that the strain belongs to a new subspecies, Acetobacter xyli...

Bacteriol. 88:1010-1018. 1964.-The properties of the pyridine nucleotide-nonlinked malic dehydrogenase of Acetobacter xylinum were investigated in the supernatant fluid obtained by high-speed centrifugation of sonic extrac...

Masa Agria is a naturally fermented maize dough produced in Colombia, very common in the traditional gastronomy. In this study we used culture-dependent and RNA-based pyrosequencing to investigate the bacterial community structure of Masa Agria samples produced in the south west of Colombia. The mean value of cell density was 7.6 log CFU/g of presumptive lactic acid bacteria, 5.4 log cfu/g for ...

For petential applicfttion in the ecenomic productien of bacterial cellu)ose, cellulose-producing Acetobacter strains capable of using suerose as a carbon source were screened for using corn steep liquor as a nitrogen source. A total of ISOe strains were iso]ated and four were selected through $tatic and shaking fiask eultuves, Much higher cellulose accumulatieii was obseryed im a jar fermentor...

Sorbitol is fermented in good yields to sorbose by some of the members of the Acetobacter species (1, 2). Resting cells of Acetobacter suboxydans may, in the absence of a source of nitrogen, oxidize sorbitol with the consumption of over 4 atoms of oxygen per molecule of substrate (3, 4). From a study of dinitrophenol action on this organism, the first step in sorbitol oxidation was shown to be ...
