Cellulase production by the RUT-C30 mutant of the fungus Triclzoderma reesei on mixtures of xylose and cellulose was studied in a fed-batch system. An initial mixture of 30 g/L xylose and 20 g/L cellulose and an intermittent feeding rate of 5 g/L/day xylose and 15 g/L/day cellulose (total of 20 g/L/day) produced the highest titer of enzyme activity of 12.5 IFPU/mL, 57% higher than for a batch s...

Six experiments were conducted to investigate the effect of a feed supplement on the performance of grazing Belgian Blue double-muscled (BBDM) heifers with an initial weight and age of 195 ± 43 kg and 190 ± 52 days. Treatments included were: Exp. 1: supplementation with beet pulp (BP): 2 kg/day per head v. ad libitum intake; Exp. 2: supplementation ad libitum with BP v. a mixture of BP and soyb...

an experiment was conducted to evaluate the effect of feed restriction (fr) and meal feeding (mf) on performance, carcass characteristics and related parameters to ascites in ross 308 male broiler chickens. five dietary treatments were 1) the control (ad libo. feeding), 2 )feed restriction from 7 to 14 days (fr14), 3) feed restriction from 7 to 21 days (fr21), 4) meal feeding from 7 to 14 days ...

the purpose of the present research was to determine the effects of intermittent and continuous training programs on some selected cardiovascular risk factors in young obese females. for this purpose, 36 obese sedentary subjects with bmi>30 were randomly assigned to three groups of intermittent exercise (mean ± sd of height, weight, and age: 163.2±5.8cm, 86.8±11.8kg, 20.7±1.3yr), continuous exe...

There is no randomized study carried out in order to compare their pharmacokinetic parameters although midazolam, as a sedative, has been widely administered via continuous infusion as well as intermittent bolus doses in mechanically ventilated critically ill patients. We prospectively investigated the effect of these two principal methods on pharmacokinetic parameters in 23 of mentioned patien...

Repeated, intermittent treatment with amphetamine (AMPH) leads to long-term neurobiological adaptations in rat brain including an increased number and branching of dendritic spines. This effect depends upon several different cell types in the intact brain. Here we demonstrate that repeated, intermittent AMPH treatment induces neurite outgrowth in cultured PC12 cells without the requirement for ...

high mortality and labor costs are associated with first-feeding sturgeon culture, particularly during the period of dietary transition from live to formulated feed. therefore we investigated the effects of various feeding treatments on the survival and growth of the persian sturgeon ( acipenser persicus ) larvae during a 20-day culture period. three replicate groups (250 fish/replicate) of fir...

this experiment was conducted to evaluate the effect of spirulina pletensis powder on the growth performances (final weight (fw), daily growth ratio (dgr), feed indices (feed conversion rate (fcr), voluntary feed intake (vfi), protein efficiency ratio (per), protein produce value (ppv), body chemical (protein, fat, moisture and ash) and fatty acid composition of mugil cephalus for 62 days. the ...
