Effect of Light and Organic Acids on Oxygen Uptake by BTAi 1, a Photosynthetic Rhizobium.
A photosynthetic rhizobium, strain BTAi 1, was cultured ex planta to investigate its photosynthetic-respiratory system and the response of this interactive system to light quantity and quality and to the addition of organic acids. Oxygen uptake, as measured with an oxygen electrode, is diminished upon illumination, with the amount of decrease related to light intensity. This oxygen-sparing effe...
متن کاملEffects of dissolved CO2 levels on the growth of Mannheimia succiniciproducens and succinic acid production.
A capnophilic rumen bacterium Mannheimia succiniciproducens produces succinic acid as a major fermentation end product under CO(2)-rich anaerobic condition. Since succinic acid is produced by carboxylation of C3 compounds during the fermentation, intracellular CO(2) availability is important for efficient succinic acid formation. Here, we investigated the metabolic responses of M. succiniciprod...
متن کاملSuccinic acid Production from Bovine Rumen – Isolation and Optimization
In this study, a novel succinic acid producing bacterium was isolated from cow bovine rumen. Two bacteria’s are found to give better results for the production of succinic acid from the isolated colonies. Different synthetic carbon sources such as glucose, sucrose, fructose, dextrose, starch and cellulose and different crude carbon sources such as rice straw, sorghum stalk, baggase and sugar mi...
متن کاملMetabolic flux analysis for succinic acid production by recombinant Escherichia coli with amplified malic enzyme activity.
A pfl ldhA double mutant Escherichia coli strain NZN111 was used to produce succinic acid by overexpressing the E. coli malic enzyme. Escherichia coli strain NZN111 harboring pTrcML produced 6 and 8 g/L of succinic acid from 20 g/L of glucose in flask culture at 37 degrees C and 30 degrees C, respectively. When NZN111(pTrcML) was cultured at 30 degrees C with intermittent glucose feeding the fi...
متن کاملThe metabolism of succinic acid in the rumen of the sheep.
Succinic acid is a major end product of two cellulose-fermenting bacteria isolated in pure culture from the rumen of cattle and sheep. Ruminococcus flavefaciens, isolated by Sijpesteijn (1948, 1949, 1951), produced some 0-5 m-mole succinic acid per m-mole cellulose (calculated as glucose) fermented. Bacteroides succinogenes, isolated from the bovine rumen by Hungate (1950), was found by this au...
