The purpose of the work was to study changes in mineral composition, lactate content and pH oral fluid under influence high-intensity physical exertion on body students with different training. Materials methods. 28 who were divided into 2 groups, depending level training, took part study. Group 1 – attended only education classes. who, addition academic classes, sports sections 3-4 times a wee...

PprI is a general switch protein that regulates the expression of certain proteins involved in pathways of cellular resistance in the extremophilic bacterium Deinococcus radiodurans. In this study, we transformed pprI into Lactococcus lactis strain MG1363 using the lactococcal shuttle vector pMG36e and investigated its effects on the tolerance and lactic acid production of L. lactis while under...

the purpose of this study was to examine the effect of coq10 supplement consumption during tapering phase on some of endurance performance indices in middle distance runners. to do this, 18 trained middle distance male runners with an age of 21±1.26 years old, a weight of 65.6±4.7kg and height of 179±2.5 were selected.  this study was based on the pre test - post test method with two experiment...

In the present work, we introduced a novel approach for microbial fatty acids (FA) production. Photosynthetic bacteria, Rhodobacter sphaeroides KD131, were cultivated in a continuous-flow, stirred-tank reactor (CFSTR) at various substrate (lactate) concentrations. At hydraulic retention time (HRT) 4d, cell concentration continuously increased from 0.97 g dcw/L to 2.05 g dcw/L as lactate concent...

The effect of pH, growth rate, phosphate and iron limitation, carbon monoxide, and carbon source on product formation by Clostridium pasteurianum was determined. Under phosphate limitation, glucose was fermented almost exclusively to acetate and butyrate independently of the pH and growth rate. Iron limitation caused lactate production (38 mol/100 mol) from glucose in batch and continuous cultu...

The frequency of extreme thermal events in temperate freshwater systems is expected to increase alongside global surface temperature. The Miramichi River, located in eastern Canada, is a prominent Atlantic salmon (Salmo salar) river where water temperatures can exceed the proposed upper thermal limit for the species (~27°C). Current legislation closes the river to recreational angling when wate...

The effect of a single bout of mild exercise on glucose effectiveness (S(G)) and insulin sensitivity (S(I)) was studied in six young male subjects by using a minimal model. An intravenous glucose tolerance test was performed under two conditions as follows: 1) 25 min after a bout of exercise on a cycle ergometer at the lactate threshold level for 60 min (Ex) and 2) without any prior exercise (C...

Lactic acid accumulates in contracting muscle and blood beginning at approximately 50-70% of the maximal O2 uptake, well before the aerobic capacity is fully utilized. The classical explanation has been that part of the muscle is O2 deficient and therefore lactate production is increased to provide supplementary anaerobically derived energy. Currently, however, the predominant view is that lact...

The activity of lactate dehydrogenase of the supernatant fraction of brain, heart, skeletal muscle, and liver of l-day and 4-, 12-, 30-, 74-, and 96-week old rats was determined to study the changes in this enzyme with increasing age. Units of enzyme per g, wet weight, of all the tissues increased during the growth phase, reaching a maximum at 30 weeks, and then decreased. NADH,:NADHn ratios, K...

Exiguobacterium sp. strain 8-11-1 is a newly isolated alkaliphile, which was reported to efficiently produce l-lactate using NaOH as the neutralizing agent. Here, we present the first 2.9-Mb assembly of its genome sequence, which may provide useful information related to its efficient lactate production and sodium ion tolerance capacities.
