| sugar substrates for l-lysine fermentation by ustilago maydis. | the extracellular production of l-lysine in media with cane sugar, blackstrap molasses, or clarified sugar-cane juice by a previously obtained mutant of ustilago maydis was studied. enzymatically inverted clarified juice (medium j-3) gave 2.9 g of lysine per liter under the following conditions: inoculum, 5%; ph 5.8; temperature, 30 c; k(la) in the fermentors, 0.41 mmoles of o(2) per liter per min; fermentation time, 72 hr. the concentrate, obtained by direct evaporation and drying of the fermen ... | 1970 | 5485081 |
| transport 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 of folinate was reduced by preincubation of cells with fluorodeoxyuridine. the transport system for fo ... | 1970 | 5473888 |

| microbial growth on c1 compounds. the role of folat in the metabolism of pseudomonas am1. | 1. the growth of pseudomonas am1 is much more sensitive to inhibition by sulphanilamide when methanol, rather than succinate, acts as the sole carbon and energy source; a sulphanilamide concentration of 1mm, which causes almost complete inhibition of growth on methanol, has little effect in a succinate medium. 2. similar results have been obtained with sulphadiazine and sulphathiazole. sulphanilic acid has little effect. 3. a similar differential sensitivity to sulphanilamide is shown by protami ... | 1966 | 4957628 |

| effect of selected lactic acid bacteria on growth of staphylococcus aureus and production of enterotoxin. | representative strains of 15 species of lactic acid bacteria were examined for their ability to influence growth of staphylococcus aureus and production of enterotoxin in associative culture. among the organisms used as effectors the streptococci were most inhibitory, followed by pediococcus cerevisiae. the lactobacilli and leuconostoc citrovorum were not inhibitory to growth and only slightly inhibitory to production of enterotoxin. enterotoxin was detected in all cultures in which the populati ... | 1973 | 4633430 |
| effect of variations in conditions of incubation upon inhibition of staphylococcus aureus by pediococcus cerevisiae and streptococcus lactis. | the effects of ph, temperature, proportion of staphylococcus aureus in the inoculum, various strains of effector organism, and various strains of s. aureus were examined for their influence on interactions between staphylococci and effector organisms in associative culture. in general, small changes in ph had little effect upon either growth of s. aureus or production of enterotoxin in associative culture. inhibition of growth of s. aureus caused by effector organisms was much greater at 25 than ... | 1973 | 4632847 |

| effect 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 folinate (10(-3)mu mole/ml) diminished the (3)h-thymidine uptake by 75%. in growing cells, the folinate-in ... | 1968 | 4230856 |

| lactate metabolism by pediococci isolated from cheese. | pediococcus pentosaceus is commonly found among the adventitious microflora of cheddar cheese. when this organism was incubated with l-(+)-lactate under anaerobic conditions, l-(+)-lactate was rapidly converted to d-(-)-lactate until racemic (dl) lactate was present. under aerobic conditions this initial reaction was followed by a slower reaction resulting in the use of both lactate isomers and in the production of acetate and co2. with intact cells the lactate oxidation system had an optimum ph ... | 1985 | 4004222 |
| isolation and characterization of pediococcus halophilus from salted anchovies (engraulis anchoita). | the presence of bacteria in salted anchovies during and at the end of the curing process was investigated. attempts to isolate bacteria under aerobic or anaerobic conditions led to the isolation of only bacteria of the genus pediococcus which were identified as pediococcus halophilus. the isolates correspond to a rather heterogeneous group in which some of the members differ in some biochemical tests from the types described in the literature. | 1985 | 3994370 |
