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.
Phytophthora spp. are mostly pathogens of dicotyledons, and are relatively host-specific parasites.Many species of Phytophthora are plant pathogens of considerable economic importance.Phytophthora infestans was the infective agent of the potato blight that caused the Great Irish Famine (1845â1849) , and still remains the most destructive pathogen of solanaceous crops, including tomato and potato.any species of Phytophthora are plant pathogens of considerable economic importance.
