Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.
Psychrotrophic bacteria are defined as those that grow at 7Â°C, although their optimal growth temperature is higher. During cold storage after milk collection they dominate the flora, and their extracellular enzymes, mainly proteases and lipases, contribute to the spoilage of dairy products.
It occurs in saprotrophs or heterotrophs, and is most often associated with fungi (for example Mucor) and soil bacteria. Saprotrophic microscopic fungi are sometimes called saprobes; saprotrophic plants or bacterial flora are called saprophytes (sapro- + -phyte, rotten material + plant).aprotrophic nutrition /saeprÉµËtrÉfÉªk/ sÃ¦prÉµËtrÉfÉªk is a process of its chemoheterotrophic extracellular digestion involved in the processing of dead or decayed organic.
