1. Validation of a modified fluorimetric assay for the screening of trichomonacidal drugs
A fluorimetric microassay that uses a redox dye to determine the viability of the flagellate Trichomonas vaginalis has been optimised to provide a more sensitive method to evaluate potential trichomonacidal compounds. Resazurin has been used in recent years to test drugs against different parasites, including trichomonadid protozoa; however, the reproducibil

2. EFICIÊNCIA DA MANIPUEIRA COMO QUELATIZANTE DE ZINCO E SEU EFEITO NA NUTRIÇÃO MINERAL DO FEIJOEIRO (PHASEOLUS VULGARIS L.) / THE EFFICIENCY OF MANIPUEIRA AS A ZINC CHELATE, AND ITS EFFECT ON ROOT GROWTH AND MINERAL NUTRITION IN BEAN CULTIVATION.
Cassava (Manihot esculenta, Crantz) is considered a vital agricultural crop due to its role as a staple food for low-income populations, primarily in the North and Northeast of Brazil, and is used as raw material for the manufacturing of a number of products such as flour and starch. During the manufacturing of these products, a potentially toxic liquid resi

3. Effect of phosphate on the multiplication of Saccharomyces cerevisiae in continuous cultivation / Efeito de fosfato sôbre a multiplicação de Saccharomyces cerevisiae em cultivo contínuo
The influence of phosphate in a continuous culture was studied using mini-fermentor on the Saccharomyces cerevisiae multiplication. Dry matter, substrate concentration, specific substrate comsumption, specific carbon dioxide release, specific oxygen uptake rates and respiration quotient , as well as phosphorous content of the cells were measured in dependenc

4. Regulation of glycolytic rate in Streptococcus sanguis grown under glucose-limited and glucose-excess conditions in a chemostat.
The biochemical mechanisms of the acidogenic potential of Streptococcus sanguis ATCC 10556 grown in glucose-excess and glucose-limited continuous culture were studied. The rate of acid production during the glucose metabolism by the cells grown under glucose limitation (glucose-limited cells) was 2.1 to 2.6 times that by the cells grown in an excess of gluco

5. Nitrogenase activity and regeneration of the cellular ATP pool in Azotobacter vinelandii adapted to different oxygen concentrations.
The in vivo activity of nitrogenase under aerobiosis was studied with diazotrophic chemostat cultures of Azotobacter vinelandii grown under glucose- or phosphate-limited conditions at different dilution rates (Ds, representing the growth rate mu) and different dissolved oxygen concentrations. Under steady-state conditions, the concentration as well as the ce

6. Regulation of glucose metabolism in oral streptococci through independent pathways of glucose 6-phosphate and glucose 1-phosphate formation.
In vivo rates of glucose uptake and acid production by oral streptococci grown in glucose- or nitrogen-limited continuous culture and batch culture were compared with the glucose phosphorylation activities of harvested, decryptified cells. The strains examined contained significant phosphoenolpyruvate-phosphotransferase system (PTS) activity, measured by a g

7. Responses of the Central Metabolism in Escherichia coli to Phosphoglucose Isomerase and Glucose-6-Phosphate Dehydrogenase Knockouts†
The responses of Escherichia coli central carbon metabolism to knockout mutations in phosphoglucose isomerase and glucose-6-phosphate (G6P) dehydrogenase genes were investigated by using glucose- and ammonia-limited chemostats. The metabolic network structures and intracellular carbon fluxes in the wild type and in the knockout mutants were characterized by

8. Bacillus subtilis Metabolism and Energetics in Carbon-Limited and Excess-Carbon Chemostat Culture
The energetic efficiency of microbial growth is significantly reduced in cultures growing under glucose excess compared to cultures growing under glucose limitation, but the magnitude to which different energy-dissipating processes contribute to the reduced efficiency is currently not well understood. We introduce here a new concept for balancing the total c

9. Appearance of Novel Glucose-6-Phosphate Dehydrogenase Isoforms in Chlamydomonas reinhardtii during Growth on Nitrate.
Extractable glucose-6-phosphate dehydrogenase activity is higher from N-limited Chlamydomonas reinhardtii cells than from N-sufficient cells. Native gels reveal that the isoform complexity varies depending on the form of N supplied. The isoforms associated with NO3- growth appear within 2 h of switching cells from NH4+ to NO3-.

10. Role of Galactose or Glucose-1-Phosphate in Preventing the Lysis of Streptococcus diacetilactis
Cells of Streptococcus diacetilactis DRCI grown at 32 C in media containing glucose as the energy source were osmotically fragile and began to lyse immediately after growth was stopped (by the action of chloramphenicol or the exhaustion of glucose), unless they were then stabilized by hypertonic medium or spermine or by storage at low pH or low temperature,

11. Control of diauxic growth of Azotobacter vinelandii on acetate and glucose.
Batch cultures of Azotobacter vinelandii were inoculated with cells pregrown on either acetate or glucose. When they were subsequently grown on a mixture of acetate and glucose, typical diauxic growth was observed, with preferential uptake of acetate in the first and glucose in the second phase of growth. Extracts from acetate-pregrown cells exhibited high a

12. Arabidopsis disrupted in SQD2 encoding sulfolipid synthase is impaired in phosphate-limited growth
The sulfolipid sulfoquinovosyldiacylglycerol is one of the three nonphosphorous glycolipids that provide the bulk of the structural lipids in photosynthetic membranes of seed plants. Unlike the galactolipids, sulfolipid is anionic at physiological pH because of its 6-deoxy-6-sulfonate-glucose (sulfoquinovose) head group. The biosynthesis of this lipid procee
