To isolate Aspergillus Niger from soil, first collect a soil sample and suspend it in sterile water to create a dilution. Then, incubate aliquots of the suspension on selective media, such as Czapek yeast extract agar, which favors fungal growth. After a few days of incubation at 25-30°C, identify and subculture the characteristic black conidia of A. niger from the colonies that develop. Finally, confirm the species through morphological and microscopic examination.

What is the meaning of isolation of aspergillus Niger?
Isolation of Aspergillus niger refers to the process of separating and identifying this particular species of fungus from a sample or environment. This can involve techniques such as culturing on specific growth media, microscopy, and biochemical tests to confirm its presence and characteristics. Aspergillus niger is a common mold known for its ability to produce enzymes and organic acids.

Three different types of fungi and what they do?
BRACKET FUNGI:-Bracket fungi are commonly found growing on trees or fallen logs in damp woodlands. They can severely damage cut lumber and stands of timber.PENICILLIUM:-Common on foodstuffs, leather, and fabrics, they are economically important in producing antibiotics organic acids, and cheeses such as English Stilton, Italian Gorgonzola, and French Roquefort.ASPERGILLUS:-Aspergillus niger causes black mold on some foods; Aspergillus niger, Aspergillus flavus, and Aspergillus fumigatus cause aspergillosis in humans. Aspergillus oryzae is used to ferment sake, and Aspergillus wentii to process soybeans.
What is the optimum temperature for the growth of pseudomonas and aspergillus Niger for bioremediation of crude oil contaminated soil?
The optimum temperature for the growth of Pseudomonas species typically ranges from 25°C to 30°C, while Aspergillus niger thrives best at temperatures between 30°C and 37°C. For bioremediation of crude oil-contaminated soil, a temperature around 30°C is often considered ideal, as it supports the growth of both organisms effectively, enhancing the degradation of hydrocarbons. Maintaining this temperature can promote microbial activity and optimize the bioremediation process.

Why is aspergillus Niger more commonly used to produce chymosin instead of e coli?
Aspergillus niger is more commonly used to produce chymosin because it has a natural ability to secrete large amounts of enzymes into the culture medium, making the extraction process easier and more efficient. Additionally, A. niger is generally recognized as safe (GRAS) for food applications, which simplifies regulatory approval compared to genetically modified organisms like E. coli. Furthermore, A. niger can often achieve higher yields of chymosin due to its robust growth and fermentation capabilities.
Why bacillus cereus more heat resistant than aspergillus Niger?
Even though they both contained spores, I believe the reason why A. Niger is less heat resistant is because it is a fungus and in the domain eukaryota. Therefore, it needs a level of humidity in the air to produce molds; an ability of most members of the fungi species. B cereus is a facultative anaerobe, and its bacterial growth generally occurs around 10-50 degrees celsius. While, a. Niger maximum temperature is around 40 degrees celsius.
