But now the parallel force is the mass of the object * g * sin (theta), where g is the acceleration due to gravity (9.8 m/s^2) and theta is the angle of the inclined plane. For the perpendicular vector, the magnitude is the mass of the object * g * cos (theta). Let's give this a try.
Microorganisms in food production Nature uses microorganisms to carry out fermentation processes, and for thousands of years mankind has used yeasts, moulds and bacteria to make food products such as bread, beer, wine, vinegar, yoghurt and cheese, as well as fermented fish, meat and vegetables.
Thousands of types of bacteria are naturally present in our environment. Microorganisms that cause disease are called pathogens. When certain pathogens enter the food supply, they can cause foodborne illness. Not all bacteria cause disease in humans.For example, some bacteria are used beneficially in making cheese and yogurt.oods, including safely cooked and ready-to-eat foods, can become cross-contaminated with pathogens transferred from raw egg products and raw meat, poultry, and seafood products and their juices, other contaminated products, or from food handlers with poor personal hygiene.
