Conversion of pteroylglutamic acid to the citrovorum factor by preparations from Lactobacillus casei.
The conversion of folic acid to citrovorum factor (N5-formyl tetrahydrofolic acid) had been demonstrated for preparations of Streptococcusfaecalis (Broquist et al., 1953), Lactobacillus arabinosus (Hendlin et al., 1953), Lactobacillus casei (Bond, 1953), and a number of animal tissues (Winsten and Eigen, 1950; Nichol and Welch, 1950; Nichol, 1952). It has been shown that ascorbic acid, ATP,3 Mg...
متن کاملThe incorporation of exogenous purines into pentose nucleic acid by Lactobacillus casei.
The complex question of the biosynthetic origin of nucleic acid purines has been approached from a number of directions. The elaboration of the over-all picture for a single organism has obvious advantages, and the experiments reported here represent a study in that direction with Lactobacillus casei as the test organism. Extensive information regarding purine utilization by L. casei is availab...

A statistically significant difference was assessed in ten untreated tropical in PGA absorption between TS and consprue (TS) and eight control subjects trol subjects was obtained only when gluutilizing a marker perfusion technique. cose was present in the perfusate. Thus, Physiologic concentrations of the vitamin unequivocal malabsorption of PGA is (2...
متن کاملCell Entrapment of Lactobacillus casei subsp. casei ATCC 39392 for Lactic Acid Production
In this study, lactic acid production by repeated batch fermentation using cell entrapped methods was compared. Barium alginate beads, agar gel and polyurethane foam cubes were employed as carriers to immobilize Lactobacillus casei subsp. casei for the purpose of L (+)-lactic acid production. Increasing concentrations of lactic acid during fermentation were better tolerated by barium alginate e...
