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.
Campylobacter (meaning curved bacteria) is a genus of Gram-negative, microaerophilic, oxidase-positive, nonfermentative bacteria. Campylobacter species are typically spiral-shaped and able to move via unipolar or bipolar flagella.Most Campylobacter species are pathogenic and can infect humans and other animals.oods implicated in campylobacteriosis include raw or undercooked poultry, raw dairy products, and contaminated produce. The infection is usually self-limiting and in most cases, symptomatic treatment by liquid and electrolyte replacement is enough in human infections. The use of antibiotics, though, is controversial.
