Kefir grains contain a complex microbial symbiotic mixture of lactic acid bacteria (Lactobacillus‚ Lactococcus‚ Leuconostoc‚ and Streptococcus spp.)‚ and yeasts (Kluyveromyces‚ Candida‚ Saccharomyces and Pichia) [Farnworth‚ 2005 & Witthuhn et al.‚ 2005]. Ricotta cheese is a high moisture soft cheese [Modler & Emmons‚ 2001]. It can be produced using cheese whey or milk‚ or a mixture of both [Pizzillo et al.‚2005]. Ricotta cheese is very mild

The Effect of Sugar Type on Rate of Energy Production During Yeast Fermentation Sarah Sulon Biology Lab 111L Dr. Murray October 25 2010 Abstract The experiment was conducted to determine the impact different sugar types have on yeast fermentation. It was hypothesized that glucose‚ sucrose and fructose would all produce energy through yeast fermentation‚ but that sucrose would have the greatest rate of energy production. The carbon dioxide production was tracked in the fermentation of yeast

2 Production of Protein from Cloned Genes Now that we have covered the basic techniques involved in gene cloning and DNA analysis and examined how these techniques are used in research‚ we can move on to consider how recombinant DNA technology is being applied in biotechnology. This is not a new subject‚ although biotechnology has received far more attention during recent years than it ever has in the past. Biotechnology can be defined as the use of biological processes in industry and technology

Chagas disease is a public health problem in Latin America with a great impact in Brazil. The latest estimates show that about seven million people in the world are infected by the kinetoplastid protozoa Trypanosoma cruzi (1). In spite of this‚ there are no vaccines against Chagas Disease (2). The current drugs used for treating this disease are effective only in the acute phase‚ with limited efficacy in the chronic stage of the disease and many toxic side effects (3) (4). Therefore‚ there is

Methods: An observation was made on whether or not the sugars‚ fructose and ribose would be fermented in yeast (Saccharomyces cerevisiae). By looking at the chemical structures of these sugars given in (Figure 1)‚ we looked for anything that might determine the metabolization of these sugars. An equal 6mL (milliliter) sample of 2.5% fructose and yeast suspension was pipetted into a fermentation tube. The same procedure above was performed with the sugar ribose which has a concentration of 2

Yeast Mutations due to Ultra-Violet Light Exposure Summary: Mutations have played one of the most important roles throughout life on Earth. Without genetic mutations there would not be the diversity of living species that we see today. Understanding how mutations work and how they are created is an important step in controlling and isolating genes for experimentation. In this experiment we tested the effects of Ultra-Violet light on growing single-celled yeast. We did this by first creating serial
