What pH and water activity (aw) levels do bacteria grow best?
pH levels vary among bacterial species. For example; acidophillic bacteria grow best at low pH. While alkalophiles grow better at alkaline (high) pH. Most bacteria grow best at high aw (>0.90). While few bacterial species such as xerophiles grow best at an aw of 0.6-0.7
Indicate one type of bacteria that would not grow due to the physical condition of incubation?
Anaerobic bacteria would not grow in an oxygen-rich environment due to their sensitivity to oxygen. These bacteria require low oxygen levels or no oxygen at all to thrive and reproduce.
What do fungi and bacteria grow from?
fungi and bacteria grow from spores.
What is the term that describes bacteria that need air to grow?
OxyphotobacteriaAnoxyphotobacteria is the term that describes bacteria that don't need air to grow
Pathogenic foodborne bacteria grow best in food with a pH of?
Pathogenic foodborne bacteria grow best in food with a pH above 4.6. This pH level provides an environment conducive for their growth and reproduction. Foods with a pH below 4.6 are generally considered less favorable for the growth of these bacteria.
Bacteria grow in what condition best?
Warm and moist.
What condition helps aerobic bacteria to grow and thrive?
The condition that helps aerobic bacteria to grow and thrive is oxygen. In stark contract an anaerobic organism does not require oxygen to grow and thrive.
At which pH level do bacteria grow best?
Bacteria typically grow best at a pH level around 6.5 to 7.5.
What is the relationship between moisture and bacteria?
When a food has a lot of moisture and is left out in certain conditions, such as in the time-temperature zone, it is likely that bacteria will grow and contaminate it. The best thing to do is refrigerate it to prevent bacteria from growing on it.
What conditions does bacteria live best?
bacteria lives in moist places and can grow in a shower
What pH and water activity (aw) levels do bacteria grow best?
pH levels vary among bacterial species. For example; acidophillic bacteria grow best at low pH. While alkalophiles grow better at alkaline (high) pH. Most bacteria grow best at high aw (>0.90). While few bacterial species such as xerophiles grow best at an aw of 0.6-0.7

At what pH does E. coli grow best?
E. coli bacteria grow best at a pH of around 7.4 to 7.6.
Which condition is more essential for food poisoning bacteria to grow darkness light air or water?
water
Pathogenic bacteria grow best at body temperature?
4.6-7.5
What is a condition that favours the growth of bacteria?
food; to survive, eg fish and poultrywarmth; grow best at 20-40 degressmoisture; needed to multiplyair; also needed to multiply (not always nessesary)time.
What temperature does bacteria grow in?
It grows best around body temp 37c
