Acetic acid bacteria in grape must

Draft Genome Sequences of Gluconobacter cerinus CECT 9110 and Gluconobacter japonicus CECT 8443, Acetic Acid Bacteria Isolated from Grape Must

We report here the draft genome sequences of Gluconobacter cerinus strain CECT9110 and Gluconobacter japonicus CECT8443, acetic acid bacteria isolated from grape must. Gluconobacter species are well known for their ability to oxidize sugar alcohols into the corresponding acids. Our objective was to select strains to oxidize effectively d-glucose.

Tannase activity by lactic acid bacteria isolated from grape must and wine.

We examined a range of oenological lactic acid bacteria species and reference strains for their potential to degrade tannins. Bacterial tannase activity was checked by a spectrophotometric and a visual reading method. None of the strains belonging to the oenological species of the genus Lactobacillus, Leuconostoc, Oenococcus or Pediococcus were tannase producers, with the exception of Lactobaci...

Deoxyribonucleic Acid Hybrids of Acetic Acid Bacteria.

De Ley, J. (State University, Ghent, Belgium), and S. Friedman. Deoxyribonucleic acid hybrids of acetic acid bacteria. J. Bacteriol. 88:937-945. 1964.-Deuterated N(15)-labeled deoxyribonucleic acid (DNA) from Acetobacter aceti (mesoxydans 4) forms hybrids with ordinary DNA from other species of this genus (A. xylinum, A. pasteurianus, A. estunensis, and possibly A. xylinoides) when the guanine ...

Coenzyme linked dehydrogenases of acetic acid bacteria.

Utilization of ethanol by acetic acid bacteria.

It is well known that the acetic acid bacteria can rapidly oxidize ethanol to acetic acid. But whether ethanol can serve as a source of carbon and energy for these bacteria has not been clearly established. Pasteur (1868) noted that Mycoderma aceti which is undoubtedly Acetobacter aceti (Frateur, 1950) can grow well in ethanol media only if acetic acid is also present. Addition of one or two pe...
