Extraction, yeast

The breakdown of glucose by yeast to give ethanol, acetic acid, and carbon dioxide was examined quantitatively by Lavoisier (1789) and Gay-Lussac (1810). From his studies (Chapter 2) Pasteur described fermentation as life without air , attributing the process to the presence of yeast cells whose effects were dependent on the vital force. The first suggestion that an unorganized ferment was responsible for fermentation was due to Traube (1858). Support for his ideas came from Berthollet (1860) who extracted yeast with water, precipitated the extract with alcohol, and found that the redissolved precipitate could...

Examination for Yeast Extract.—Yeast extracts contain principally marked quantities of xanthine bodies (xanthine, adenine, camine, etc.), but, unlike meat extracts, they contain no creatine or creatinine. It is hence easy to detect meat extract in mixtures of this with yeast extract the inverse problem, which is the one usually presenting itself, is not so easy. Of the different methods proposed to meet this case, some of which are empirical, the only one capable of giving reliable results is that of Micko,1 based on the detect bn of a special substance of the nature of gum, found only in yeast extracts. This method is as follows ... 

Brewers dried yeast is the dried, non-fermentative, non-extracted yeast of the botanical classification Saccharomyces resulting as a by-product from the brewing of beer and ale. The traded product must contain not less than 35% CP. It must be labelled according to its CP content IFN 7-05-527 Yeast brewers dehydrated. 

A spore suspension was prepared with 5 ml of a 0.9% sodium chloride solution obtained from a 7-10 day old, malt extract-yeast extract agar slant culture of Mortierella maculata nov. spec. E-97 [NCAIM(P)F 001266] strain able to 6-p-hydroxylate compactin and the suspension was used to inoculate 100 ml inoculum medium PI (glucose-50 g, soybean meal-20 g, in 1000 ml tap water) sterilized in a 500 ml Erlenmeyer flask.

With a knowledge of their particular requirements, it should be practicable to make for most yeasts a chemically defined medium in which there can be nearly maximal rates of growth. Often, however, faster growth occurs in a medium such as that containing malt extract, yeast extract, and peptone, with D-glucose as the main source of...

Yeast Extract. Yeast enzyme concentrate (YEC) was purchased from Sigma Chemical Company (St. Louis, MO). Stock solutions were made at 10 mg lyophilized powder per ml. The specific activity of ADH in this mixture was found to be 17 U/mg protein using an assay described by Vallee and Hoch (10).

Metabolic inactivation, whether taking place in the e,r, or at other sites, is often accidentally inhibited by other drugs. Thus many patients have died as a result of the simultaneous administration of an inhibitor of monoamine oxidase (an enzyme present in mitochondria) and an amine drug which is not toxic on its own. These monoamine oxidase inhibitors, such as tranylcypromine 9,47), are prescribed as mood-elevators in depressive illnesses. Until their synergistic properties were realized, they caused many deaths after usually safe doses of amphetamine, pethidine, and amitriptyline, or after the patient had consumed food rich in pressor amines such as tyramine such foods are red wine, meat-extract, yeast-extract, broad beans, and particularly cheese. These are examples of unfortunate synergism, but many favourable cases are known, examples of which will now be given.

Of interest in connection with the discussion on pages 249 to 250 is a recent publication by Eyring, Johnson, and Gensler (67a) on the activity of extracted yeast invertase in relation to pressure, temperature, and pH. The reduction in activity on either the acid or alkaline side of the optimum pH of 4.5 is partially reversible by a hydrostatic pressure of 680 atmospheres. Analysis of the quantitative relation between increase in activity...
