What is happening during the stationary phase?
growth is followed by the stationary phase, in which the size of a population of bacteria remains constant, even though some cells continue to divide and others begin to die. During the stationary phase, the rate of bacterial cell growth is equal to the rate of bacterial cell death.
How can we avoid lag phase?
In bacterial physiology, lag phase is defined as the phase which is necessary for adaption of cells to new environment. During this phase the bacteria grow and the size increases; but the population density is almost constant. In textbook, it is recommended to have at least 5% of inoculum to decrease the lag phase.
Does bacteria need air to grow?
Whereas essentially all eukaryotic organisms require oxygen to thrive, many species of bacteria can grow under anaerobic conditions. Bacteria that require oxygen to grow are called obligate aerobic bacteria. In fact, the presence of oxygen actually poisons some of their key enzymes.
What surfaces do bacteria grow best on?
Stainless steel was the best material at resisting bacterial growth followed by porcelain, solid surface material and then plastic. Following this group was tile, varnished wood, and marble. Glass was the worst at resisting the growth of the bacterial colonies.
What foods provide the right environment for bacteria to grow?
Foods that are dehydrated or freeze-dried can be stored for much longer as the moisture has been removed. Food – Food provides energy and nutrients for bacteria to grow. High risk foods particularly protein foods such as chicken and dairy products are rich in nutrients and moisture and so promote bacterial growth.
Can bacteria grow on stainless steel?
Stainless steel is the gold standard for kitchen appliances and cookware, but bacteria can grow on these surfaces, contaminating food. Stainless steel is the gold standard for kitchen appliances and cookware, described as modern and sleek. But bacteria can grow on stainless steel surfaces, contaminating food.
