Stress- and Growth Phase-Associated Proteins of Clostridium acetobutylicum.
The response of Clostridium acetobutylicum ATCC 4259 to the stresses produced by a temperature upshift from 28 degrees C to 45 degrees C and by exposure of the organisms to 0.1% n-butanol or to air was examined by analysis of pulse-labeled proteins. The stress response was the induction of the synthesis of a number of proteins, some of which were elicited by the three forms of stress. Eleven he...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Cellulolytic Activity of Clostridium acetobutylicum.
Clostridium acetobutylicum NRRL B527 and ATCC 824 exhibited extracellular and cell-bound endoglucanase and cellobiase activities during growth in a chemically defined medium with cellobiose as the sole source of carbohydrate. For both strains, the endoglucanase was found to be mainly extracellular (70 to 90%) during growth in continuous or batch cultures with the pH maintained at 5.2, whereas t...
متن کاملThe amylase of Clostridium acetobutylicum.
The purification and concentration of enzymes by adsorption on charcoal, tannin, aluminum hydroxide, ion exchange resins, and so forth, has been an established practice in the laboratory. Some years before this work was done in 1949, alkali-cooked lignin was used as an adsorbent for mold and malt amylase (Wallerstein et al., 1945). In this paper is described our study of the adsorption of the a...
متن کاملEmended descriptions of Clostridium acetobutylicum and Clostridium beijerinckii, and descriptions of Clostridium saccharoperbutylacetonicum sp. nov. and Clostridium saccharobutylicum sp. nov.
On the basis of 16S rRNA gene sequencing and DNA-DNA reassociation, industrial solvent-producing clostridia have been assigned to four species. In this study, the phenotypic characteristics of Clostridium acetobutylicum, Clostridium beijerinckii, 'Clostridium saccharoperbutylacetonicum', and an unnamed Clostridium sp. represented by the strains NCP 262T and NRRL B643 are compared. In addition, ...
