At first glance, the undergraduate biology curriculum at the Johns Hopkins University doesn't look all that different from other biology programs. All the usual suspects are on the schedule: General Biology and Cell Biology, Virology and Genetics, Immunology and Biochemistry. But down at the bottom of that list is something that you don't see every day — Biology 420: Build-a-Genome. While the c...

Forty-eight West African Dwarf sheep and goats (twenty-four of each) with liveweights ranging from 8 to 15 kg were allotted in groups of eight to six diets containing 0%, 15%, 30%, 45%, 60% and 75% brewers’ dried grains (BDG) fed ad libitum together with 0.5 kg/head/ day fresh forage. After twenty-five weeks, all the animals were slaughtered and the carcass evaluated. Brewers, dried grains did ...

From Austrian monks to American craft brewers, beer geeks are everywhere. But making a good beer not only depends on the best ingredients, but also the best yeast. The beer world is divided into ales and lagers. Lager yeasts are hybrid strains, made of two different yeast species, Saccharomyces cerevisiae and S. eubayanus (discovered in 2011). In a new study in the journal Molecular Biology and...

Since the pioneer work of Rogers (1914) on drying cultures from the frozen state and the wide application of this procedure to bacteria, the lyophil process has been shown to be a successful method for the preservation of yeast cultures in a viable state over extended periods (Elser et al., 1935; Wickerham and Andreasen, 1942; Wickerham and Flickinger, 1946). The fundamental value of this metho...

Biopolymers are a suitable alternative for the ongoing problem of plastic accumulation, even though commercialization is difficult, which reflected in price product. However, costs can be reduced if active sludge bacteria and cheap, accessible substrates such as waste brewer’s yeast used. Waste rich source carbon nitrogen widespread substrate various industries. Thus, cultivation was performed ...

The effects of diets with different starch sources on the total tract apparent digestibility and glucose and insulin responses in cats were investigated. Six experimental diets consisting of 35% starch were extruded, each containing one of the following ingredients: cassava flour, brewers rice, corn, sorghum, peas, or lentils. The experiment was carried out on 36 cats with 6 replications per di...

The aim of this study was to assess the effect of Brewers' yeast extract (BYE) on daily activity in a mouse model of chronic fatigue syndrome (CFS). CFS was induced by repeated injection of Brucella abortus (BA) antigen every 2 weeks. BYE was orally administered to mice in a dose of 2 g per kg per day for 2 weeks before injecting BA and for 4 weeks thereafter. We evaluated daily running activit...
