Plasmid DNA in Strains of Pediococcus cerevisiae and Pediococcus pentosaceus.
Five parental strains of Pediococcus were examined for plasmid content. Each strain contained three to six resident plasmids, ranging in size from 4.5 to 39.5 megadaltons. A bacteriocin-like substance produced by Pediococcus cerevisiae FBB63 was tentatively linked to a 10.5-megadalton plasmid after being cured with novobiocin.
متن کاملEffect of folinate on thymidine uptake by Pediococcus cerevisiae.
Uptake of (3)H-thymidine by resting cells of Pediococcus cerevisiae was found to be energy- and temperature-dependent. The pH optimum was between 6.5 and 8.0, and after 2 min of incubation most of the radioactivity was found in the deoxyribonucleic acid (DNA) fraction. Iodoacetate at a concentration of 10(-2)m caused a 50% inhibition of uptake. Preincubation of resting cells for 10 min with fol...
متن کاملTransport of folinate and related compounds in Pediococcus cerevisiae.
The properties of folinate and 5-methyltetrahydrofolate (5-CH(3)-H(4)PteGlu) transport mechanism of Pediococcus cerevisiae were studied. The uptake was dependent on temperature, pH (optimum for both compounds at pH 6.0), and glucose. Iodoacetate, potassium fluoride, and sodium azide inhibited the uptake. 5-CH(3)-H(4)-PteGlu was apparently not metabolized but folinate was metabolized. Metabolism...
متن کاملCatalase enzyme in mitochondria of Saccharomyces cerevisiae
Catalase and superoxide dismutase activities have been explored in the yeast Saccharomyces cerevisiae during batchwise growth experiment. During the diauxic growth in YPD medium high Ys values were obtained (0.415 0.423) and correlation between the total activities of both enzymes has been found. A mitochondrial fraction from three type strains of Saccharomyces cerevisiae has been isolated. The...
متن کاملUptake and Metabolism of Folate by a Folate-utilizing Mutant of Pediococcus cerevisiae
Pediococcus cerevisiae 8081, which uses folinic acid for growth, and its nutritional mutant 8081/S, which utilizes folate, were compared with respect to their ability to take up and metabolize folate. In contrast to the parent strain 8081, which takes up very little folate, the uptake of folate by the mutant is a concentrative, saturable, and energydependent process. At low extracellular concen...
