Yogurt is part of our diet from ancient time. It is been produced and consumed from thousand of years. It is obtained from milk. The lactose sugar of milk is fermented by Lactobacillus delbrueckii subsp. bulgaricus and convert it to produce lactic acid, forming yogurt and tastes sour. There are many other lactose fermenting bacteria […]

Introduction – Bacterial Growth is affected by nutritional and physical factors. The nutrients means the organic and inorganic material whereas the physical factors means pH, temperature, aerobic/anaerobic conditions. The bacteria need the nutrition and optimum physical environment to conduct its molecular, physiological activity and to multiply. The bacteria needs a physical environment for carrying out

Carl Woese‘s Classification was introduced by Carl Woese in 1990. It classified the life forms into three-domains which include archaea, bacteria, and eukaryote. Introduction to Carl Woese’s Classification Life on earth was initiated 3.7 billion years ago. Evolution of the first life form resulted into diverse forms of living organisms from unicellular to multicellular. The natural
