Physiology of Zymomonas mobilis: Some Unanswered Questions
2006The ethanol-producing bacterium Zymomonas mobilis can serve as a model organism for the study of rapid catabolism and inefficient energy conversion in bacteria. Some basic aspects of its physiology still remain poorly understood. Here, the energy-spilling pathways during uncoupled growth, the structure and function of electron transport chain, and the ...

Transformation of Zymomonas mobilis by a hybrid plasmid
Plasmid, 1984The transformation of Zymomonas mobilis by plasmid DNA was achieved using a modification of the CaCl2 method for Escherichia coli. The highest frequency of transformation obtained was 5 X 10(3) transformants/micrograms DNA. The success of the method depended upon the use of a plasmid which is a cointegrate between a Z. mobilis cryptic plasmid and an E.

Cosmeceutical properties of levan produced by Zymomonas mobilis
International Journal of Cosmetic Science, 2006Levan, a polysaccharide that can be produced by both plants and micro‐organisms, is a sugar polymer composed of fructose, with‐2,6 linkages. Here, we have attempted to assess the possible use of levan produced by Zymomonas mobilis as a cosmeceutical ingredient.

Formation of sorbitol by Zymomonas mobilis
Applied Microbiology and Biotechnology, 1984Sorbitol is formed as the major by-product in ethanol fermentations by Zymomonas mobilis when both glucose and fructose are present in the fermentation medium. The amount of sorbitol produced was equivalent to as much as 11% of the original carbon source, decreasing the ethanol yield correspondingly.

Electron transport chain of Zymomonas mobilis
Archives of Microbiology, 1990The interaction of the membrane-bound glucose dehydrogenase from the anaerobic but aerotolerant bacterium Zymomonas mobilis with components of the electron transport chain has been studied. Cytoplasmic membranes showed reduction of oxygen to water with the substrates glucose or NADH. The effects of the respiratory chain inhibitors piericidin, capsaicin,

Metabolic Analysis of Zymomonas mobilis
2000Zymomonas Mobilis is an anaerobic, Gram-negative bacterium producing ethanol from glucose via the Entner-Doudoroff (2-keto-3-deoxy-6-phosphogluconate, KDPG) pathway in conjunction with the enzymes pyruvate decarboxylase and alcohol dehydrogenase. The organism was originally isolated from fermenting sugar-rich plant saps, e.g., in the mexican pulque ...

การผลิตเอทานอลจากปลายข้าวโดย Zymomonas mobilis TISTR405 ในการหมักแบบกึ่งกะ
งานวิจัยนี้ ศึกษาการผลิตเอทานอลในกระบวนการหมักแบบกึ่งกะ โดยใช้น้ำต้อยที่ได้จากการย่อยปลายข้าวเป็นแหล่งคาร์บอน จุลินทรีย์ที่ใช้ในกระบวนการหมักเป็นเชื้อแบคทีเรียสายพันธุ์ Zymomonas mobilis TISTR 405 การทดลองเริ่มจากการคัดเลือกลูกแป้งข้าวหมากที่รวบรวบจากแหล่งต่างๆ มาศึกษาความสามารถในการเปลี่ยนปลายข้าวที่นึ่งจนสุก ให้กลายเป็นน้ำตาลที่มีความเข้มข้นสูงที่สุดopenaire +1 more source
[Research progress of ethanologenic Zymomonas mobilis].
Wei sheng wu xue bao = Acta microbiologica Sinica, 2006Zymomonas mobilis is one of the natural ethanologenic microbes. With the unique Entner-Doudoroff pathway and some other special pathways of glycolytic and energetic metabolism, Z. mobilis has remarkable characters of higher rate of ethanol production and higher tolerance to ethanol.
