Ⅰ. 개요
미생물을 포함한 모든 생명체는 생명을 유지하고 성장하기 위해 에너지와 세포의 구성성분을 요구한다. 에너지 생산과 세포 구성성분으로 필요한 물질을 영양분이라 한다.
미생물들은 각기 특성 있는 영양요구조건이 있으며, 영양조건이 다양하기에 미생물 배지의 종류도 다양하다. 동R

Foodborne diseases pose a widespread threat to human health and they are an important cause of reduced economic productivity even in advanced countries which have modern food processing and distribution systems. Although the amount of foodborne disease caused by pathogenic bacteria in the United States is not known with accuracy, it was estimated in 1994 by a task force of the Council for Agricul

caused by Staphylococcus aureus ?
Skin infections
Staph infections of the skin can progress to impetigo
When the bacteria enter the bloodstream and spread to other organs, a number of serious infections can occur.
Staphylococcal food poisoning is an illness of the bowels
That causes nausea, vomiting, diarrhea, and dehydration.
Caused by eating foods contaminated with toxins .
Cause
Infectious
Infected by a variety of pathogenic bacteria like bacteria, virus, fungus and so one/
Noninfectious
Allergy response as from exterior material.

is subject to thousands of pounds of pressure, effectively wiping out any potentially pathogenic bacteria without exposing the product to heat that can damage the juices flavor, color and nutritional value.
This process now allows for a 40-day shelf life, unheard of for fresh juice. Evolution products currently go from the tree to shelf in less than 7 days, ensuring the juice is truly fresh.
