Homogenizer and ultrasonicator that we call as mechanical methods were used in the lab scale production of alcohol free reduced glutathione (alcohol free GSH) from baker’s yeast. The study was done to determine the effects of specific parameters of the methods and the pH of the medium on the production of the GSH. The <...

Researchers add serum to a classical medium at concentrations of 5 to 10% (v/v) to grow cellsin-vitro culture media. Unfortunately, serum is a poorly defined culture medium componentas its composition can vary considerably while serum-free cell culture media are an excellentalternative to standard serum-containing media and offer several major advantages. Advantagesof us...

erythromycin production is clearly enhanced by the addition of vegetable oils. however,whether this positive effect is brought about by the triglyceride or non-triglyceride fraction, isnot clear. the non-triglyceride portions of the oils accumulate in the waste during the refiningprocess leaving mainly triglycerides in the refined oil. in this research, sub-fractions of soybeanoil, including le...

We prove a number of useful results about probabilistic context-free grammars (PCFGs) and their Gibbs representations. We present a method, called the relative weighted frequency method, to assign production probabilities that impose proper PCFG distributions on finite parses. We demonstrate that these distributions have finite entropies. In addition, under the distributions, sizes of parses ha...
