What conditions are the most favourable for microbial food production?…
What conditions are the most favourable for microbial food production?
Needs nutrients to grow
Bacteria need a water source to grow otherwise they'll die.
Kitchens and bathrooms prone to bacterial growth
Water content in food allows bacteria to grow faster
Human body temperature
Ideal bacteria growth
Temperature depends on what type of bacteria it is
The Danger Zone (temperature ideal for bacterial growth)
Between 5-63 degrees
This is usually the room temperature
Under UV rays
Bacteria doesn't grow instantly
Both time and correct temperature is needed for bacteria to multiply over time.
Good to measure acidity or alkalinity
Bacterial is most likely to grow with a neutral pH level
Greatly effects oxygen growth
Sealing foods prevents bacterial growth
Three different groups in which oxygen can grow
Must have oxygen to grow
Can grow with or without oxygen
Cannot grow if oxygen is present
Foods produced by microbials
A yeast called Saccharomyces cerevisiae is mixed with sugar, flour and warm water to make bread.
Good for bacterial growth
High percentage of moisture
The protein portion in milk is used to produce cheese
Protein portion is called casein
Bacteria can adapt to different environments
