FOOD TECHNOLOGY

Detailed explanation-1: -Various kinds of bacteria need different amounts of oxygen to live. To process their growth, microorganisms need specific nutrients including metal ions, carbon, nitrogen, phosphorus, and sulphur. When bacteria reach a certain size, they begin to multiply asexually through a process called binary fission.

Detailed explanation-2: -Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic.

Detailed explanation-3: -Physical requirements for Bacterial Growth Bacteria not only need nutrients for its growth but also need ambient physical environment such as temperature, pH and gases. Such physical environment is need for carrying out the biochemical and molecular pathways of bacterial cell.

Detailed explanation-4: -FOOD-MOISTURE-TIME-TEMPERATURE-OXYGEN All bacteria need is food and moisture to survive. Time; we know is needed, to allow them to multiply. The temperature has to be right for the specific type of bacteria, but most like temperatures within what we call the ‘danger zone’.
