Endo-beta-Glucanase from Acetobacter xylinum: Purification andCharacterization.

A cellulose-producing acetic acid bacterium,Acetobacter xylinum KU-1, abundantly produces an extracellularendo-beta-glucanase (EC 3.2.1.

Three distinct quinoprotein alcohol dehydrogenases are expressed when Pseudomonas putida is grown on different alcohols.

A bacterial strain that can utilize several kinds of alcohols as its sole carbon and energy sources was isolated from soil and tentatively identified as Pseudomonas putida HK5. Three distinct dye-linked alcohol dehydrogenases (ADHs), each of which contained the prosthetic group pyrroloquinoline quinone (PQQ), were formed in the soluble fractions of this strain grown on different alcohols. ADH I was formed most abundantly in the cells grown on ethanol and was similar to the quinoprotein ADH reported for P.

Methanol and ethanol oxidase respiratory chains of the methylotrophic acetic acid bacterium, Acetobacter methanolicus.

Acetobacter methanolicus is a unique acetic acid bacterium which has a methanol oxidase respiratory chain, as seen in methylotrophs, in addition to its ethanol oxidase respiratory chain. In this study, the relationship between methanol and ethanol oxidase respiratory chains was investigated. The organism is able to grow by oxidizing several carbon sources, including methanol, glycerol, and glucose.

Change of the terminal oxidase from cytochrome a1 in shaking cultures to cytochrome o in static cultures of Acetobacter aceti.

Acetobacter aceti has an ability to grow under two different culture conditions, on shaking submerged cultures and on static pellicle-forming cultures. The respiratory chains of A. aceti grown on shaking and static cultures were compared, especially with respect to the terminal oxidase.
