Buchanan, B. B. (Duke University, Durham, N.C.), and Leo Pine. Relationship of carbon dioxide to aspartic acid and glutamic acid in Actinomyces naeslundi. J. Bacteriol. 89:729-733. 1965.-CO(2), which was essential for the fermentation of glucose to succinic acid by Actinomyces naeslundii, was also required for the synthesis of internal aspartic acid, for which the cells lack a permease.

Recognizing the importance of succinic acid as one most relevant platform molecules, present study assesses production from waste apple slurry/pomace a sustainable and renewable feedstock. The assessment has been undertaken by incorporating technical economic considerations in analysis while also comparing two scenarios. aforementioned have applied utilizing process simulation results, generate...

Anaerobes, in particular Bacteroides spp., are the predominant bacteria present in mixed intra-abdominal infections, yet their critical importance in the pathogenicity of these infections is not clearly defined. Succinic acid, a major fatty acid by-product of Bacteroides metabolism, was tested for its effect on neutrophil function to determine whether it might play a role in enhancing the virul...

samples were thus obtained for subsequent anaerobic assay with P. cereviseae. Typical assay results are indicated in Fig. 2. There is a marked increase in P. cereviseae activity caused by incubation of C. sporogenes with folic acid as compared with the corresponding nonincubated system. This activity could not be attributed to endogenous cell activity, and was not due to the utilization of aryl...

[reaction: see text] The Rh-TangPhos catalyst has been used for asymmetric hydrogenation of itaconic acid and enol acetate derivatives. A variety of chiral 2-substituted succinic acids and chiral acetates have been obtained in excellent ee values (up to 99% ee).

Stereospecificity of Some Invertebrate Lactic Dehydrogenases by Mary Jacobs Scheid 1. It has been assumed that only among unicellular organisms did nicotin¬ amide adenine dinucleotide (NAD)-linked lactic dehydrogenases occur. All higher animals were thought to possess Lspecific lactic dehydro¬ genases. It was discovered recently, however, that many species of invertebrates possess lactic dehydr...

Nowadays, increasing use of latex products in the healthcare area has also led to an increase in new scientific controls of raw material and manufactured products in order to maintain higher standards in quality control. Since field latex is a rich environment for microbial growth, in the absence of adequate preservation, the carbohydrates that it contains become microbiologically oxidised to t...

New approach for preparation of CMC hydrogels was undertaken through reacting CMC with either malic, succinic or citric acid. Characteristics of the hydrogels, as monitored by the swelling behavior, FTIR, SEM, EDX, TEM and XRD were dependent on nature and concentration of the polycarboxylic acid, time and temperature of curing. The best practice achieved from these studies was harnessed to synt...

A novel compound, 4-amino-4-cyanobutyric acid, was isolated and identitled from cultures of an unidentified psychrophilic basidiomycete. Triple labeling experiments in vivo involving the simultaneous administration of KW15N and succinic semialdehydeJ4C to fungus cultures showed that these compounds along with ammonia are precursors of 4amino-4-cyanobutyric acid. In addition, cell-free extracts ...

Through the demonstration of the importance of biotin to oleic acid synthesis, to oxalacetate decarboxylation and carbon dioxide fixation, and to certain amino acid deamination reactions, as reviewed by Stokstad and Jukes (1949), and to citrulline synthesis (MacLeod et at., 1949), it is becoming increasingly apparent that the coenzyme form of this vitamin may be concerned in many different type...
