Definition - What does Tensile Strength mean? Tensile strength is the ability of a material to withstand a pulling (tensile) force. It is customarily measured in units of force per cross-sectional area. This is an important concept in engineering, especially in the fields of material science, mechanical engineering and structural engineering.
Microorganisms In A Compost Pile. Microorganisms such as bacteria, fungi, and actinomycetes account for most of the decomposition that takes place in a pile. They are considered chemical decomposers, because they change the chemistry of organic wastes.
Microbial spoilage. There are three types of microorganisms that cause food spoilage -- yeasts, moulds and bacteria. 1  Yeasts growth causes fermentation which is the result of yeast metabolism.2  There are two types of yeasts true yeast and false yeast. 3  True yeast metabolizes sugar producing alcohol and carbon dioxide gas.icrobial spoilage.
