pH Level
Maximise enzyme activity at a pH level of pH 8.5
Temperature
Grows optimally in 17-25 degree celsius
Nutrient requirement
Chytrids live in their food and have an absorptive mode of nutrition in which they secrete digestive enzymes and absorb the breakdown products.
Zygomycota
Example
Rhizopus stolonifer
pH Level
6.0-7.0
Temperature
26 degrees celsius
Water Activity
0.91
Oxygen requirement
Aerobic
Culture media
Results indicated a better definition of mycelia, sporangia, and sporangiospores when isolates were grown on potato-dextrose-agar (PDA)
Nutrient requirement
It feeds on dead, damp, and decaying matter, such as soil. Can parasitic because it obtains nutrients from living organisms, causing the food to rot.
Deuteromycota
Example
Penicillium roqueforti
pH Level
2.9 and 5.6
Temperature
An optimum of 26.9 degree celsius, and a maximum of 33.5 degrees celsius
Water Activity
0.83 and 0.99
Oxygen requirement
Lowest oxygen requirements for growth of any Penicillium species
Culture media
Malt extract agar, Cornmeal Agar (CMA) and Potato Carrot Agar (PCA)
Nutrient requirement
Obtain from the milk or curd nutrient content as well as the moisture availability.
Ascomycota
Saccharomyces cerevisiae
pH Level
4 to 6
Temperature
40 degrees celsius
Water Activity
0.85
Oxygen requirement
Aerobically or anaerobically
Culture media
Malt Agar, Potato Carrot Agar and Potato Dextrose Agar
Nutrient requirement
Obtain their nutrition from different sources ranging from dead and decaying matter to nutrition from compounds synthesized by other organisms
