happens more swiftly at warmer temperatures than it does at cold temperatures. Spoiled Milk All milk‚ even pasteurized milk‚ contains bacteria. As bacteria go about happily with their lives‚ they eat the natural sugars in milk‚ called lactose. As they digest lactose‚ a number of byproducts are created‚ including lactic acid. When the amount of lactic acid in the milk begins to increase‚ the pH drops and the casein molecules begin to clump. The high levels of lactic acid are also what give spoiled

Celiac disease‚ more commonly known as gluten intolerance‚ affects one in 133 Americans. This lifelong disease causes intestinal problems when eating gluten‚ which is the common name for offending proteins in wheat (including durum‚ semolina‚ spelt‚ kamut‚ einkorn‚ and faro)‚ rye‚ barley and oats. Gluten is like poison to people with celiac disease. Terms to beware of: Durum flour‚ couscous‚ semolina‚ spelt‚ kamut‚ bulgur and triticale‚ a grain crossbred from wheat and rye‚ are all names

The rest of the product consists of small amounts of fat‚ milk sugar (lactose) and often sweeteners and flavorings. While this product is still excellent for building muscle‚ some may experience bloating and gas because of the lactose. Whey Isolate Whey isolates are a more pure extraction of whey proteins. Isolate powders consist of at least 90% pure whey proteins and some are 100% pure. The higher

The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and

P.vulgaris is associated with nosocomial infection‚ and has the ability to degrade urea to ammonia by production of the enzyme urease. McConkey agar contains lactose‚ which P.vulgaris does not ferment. It ferments glucose‚ sucrose‚ galactose‚ glycerol occasionally maltose with gas production‚ but never lactose. P.vulgaris ferments liquefies gelatin‚ casein‚ and blood serum‚ curdling milk with acid production. P.vulgaris provides a positive result for: sulfur reduction‚urease

Proteus mirabilis is characterized by their motility‚ its ability to distinguish maltose‚ and its inability to distinguish lactose. Proteus has the ability to stretch itself out and secrete a polysaccharide when in contact with solid surfaces‚ in result making it extremely motile on items like medical equipment such as an indwelling urinary catheter. Proteus is part of the normal
