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.
Most commonly used microorganisms are yeast, bacteria, moulds, or a combination of these. A good example of microorganism usage in food production is the process of fermentation, which results in the production of organic acids, alcohols and esters. These help to either: 1  Preserve the food.athogenic microorganisms cause food-borne infections or intoxication, and include bacteria, viruses, parasites and moulds. It is important to note that pathogenic bacteria and viruses usually do not cause food spoilage, their contamination cannot be seen nor tasted.
