generally ranges from about 2.4-4.2 and contain sugar (4.7g)‚ fat (3.3g)‚ carbohydrates (4.7g)‚ and proteins (3.3g). Although molds can and do grow on the surface of yogurt if the yogurt are exposed to air‚ the high moisture contents favors the faster-growing yeasts and bacteria. The deficiency of vitamin B discourages some bacteria. The normal change to be expected in raw yogurt in room temperatures is an alcoholic fermentation by yeasts‚ followed by the oxidation of the alcohol and yogurt acids by

Study yielded 5 new bioactive compounds: two secolignans‚ two tetrahydrofuran lignans‚ and one highly methoxylated dihydronaphthalenone. • Proximate analysis of leaves yielded a high ash content‚ a higher crude fiber content‚ and a still higher carbohydrate content. Mineral analysis showed low manganese‚ iron‚ zinc and copper‚ with high sodium content. Phytochemical screening yielded alkaloids‚ cardenolides‚ saponins and tannins. • An ether soluble fraction of the whole plant yielded 4‚7-dimethoxy-5-(2-propenyl)-1

Sourdough is the result of a fermentation process in which flour and water are mixed and fermented with microbes‚ especially LAB and yeasts (De Vuyst and Neysens 2005; Corsetti and Settanni 2007a; De Vuyst and Vancanneyt 2007; De Vuyst et al. 2009). Nowadays‚ sourdough is extensively used for the manufacture of a variety of products particularly breads and others‚ such as cakes‚ crackers‚ pizza‚ various sweet baked goods‚ and gluten-free products (Gobbetti 1998; De Vuyst et al. 2009).

compound like sucrose‚ Ba (OH) 2 for fermentation process‚ and use simple distillation method to purification from the fermentation mixture. Abstract and Theory: There are many techniques that are used to purify liquid. The one that is going to use for this lab is simple distillation. It is a process of which separating a mixture based on the tendency of the mixture to vaporize into a boiling liquid. For this particular experiment‚ a disaccharide carbohydrate sugar like sucrose will mix with yeast

tapai‚ cheese‚ bread and others. Starter cultures is used in these food production. A starter culture is a microbiological culture which actually perform fermentation. These starters usually consist of a cultivation medium‚ such as grains‚ seeds‚ or nutrient liquids that have been well colonized by the microorganisms used for the fermentation. These starters are formed using a specific cultivation medium and a specific mix of fungal and bacterial strains. microorganisms used in starters include

A FERMENTER OR BIOREACTOR MICROBE INPUT :- The microorganisms that will carry out the fermentation process are cultured separately until they are growing well. These are introduced into the fermenter through the microbe input. NUTRIENT INPUT :- The microorganisms require an energy source to carry out fermentation. The energy source is usually a carbohydrate. Growth materials like amino acids for protein synthesis are also added through the nutrient input. STERILE CONDITIONS:- It is necessary

It contains lactose‚ sucrose‚ a small amount of glucose (dextrose)‚ ferrorus sulfate and the pH indicator phenol red. As with the phenol red fermentation broths‚ if an organism can ferment any of the three sugars present in the medium‚ the medium will turn yellow. If an organism can only ferment dextrose‚ the small amount

First‚ carbohydrate fermentation was tested in various sugar solutions (glucose‚ sucrose‚ arabinose‚ mannitol‚ lactose‚ and galactose) for the unknown. Cells were taken from culture and inoculated into vials filled with a phenol red sugar solution and a filled Durham tube which was turned upside down. The cells were left to grow overnight and observed the next day for color changes and bubble production which gave positive results for carbohydrate fermentation. The next test was a

Please answer the following questions. Your answer for each question should be a minimum of 150 words (half page). Please number your answers with the number of the question you are answering. 1. Koch was the first scientist to prove that bacteria actually cause disease. He scientifically demonstrated that a disease is caused by a particular organism. He created four general guidelines to aid in identification of disease causing pathogens. These guidelines developed from his work with purified
