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.
Glucoamylase is produced by various microorganisms, including fungi such as Aspergillus niger and Rhizopus species, as well as some bacteria like Bacillus species. It is also found in small amounts in human saliva.
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.
lignocellulosic materials or plant wastes. dried leaves, corn cobs, saw dust and anything that has cellulose or hemicellulose. A. niger then produces enzymes that would degrade these materials and take up carbon for their growth and metabolism. in return, they produces enzymes and other metabolic products having industrial and commercial significance.
Enzymes are commonly produced by microorganisms, particularly bacteria and fungi. For example, the bacterium Bacillus subtilis and the yeast Saccharomyces cerevisiae are frequently used in industrial enzyme production. Additionally, certain molds, like Aspergillus niger, are also utilized for their ability to produce a wide range of enzymes, including amylases and proteases. These organisms are favored due to their rapid growth rates and ability to secrete large quantities of enzymes into their surrounding environment.
Amylases are widespread in animals, fungi, plants, and are also found in the unicellular eukaryotes, bacteria and archaea. Ptyalin, a salivary α-amylase (α-1,4-α-D-glucan-4-glucanohydrolase) is one of the most important enzymes in saliva. It is known to be mainly involved in the initiation of the digestion of starch in the oral cavity. Fungal sources of α-Amylase are confined to terrestrial isolates, mostly to Aspergillus species and to only few species of Penicillium, P. brunneum being one of them. The fungal source used predominantly for commercial production of α-Amylase are the strains of Aspergillus spp. Aspergillus oryzae, A. niger and A. awamori are most commonly used species for commercial production among several others. α-Amylase can be produced by different species of bacteria, but for commercial applications α-amylase is mainly derived from the genus Bacillus. α-Amylases produced from Bacillus licheniformis, Bacillus stearothermophilus, and Bacillus amyloliquefaciens find potential application in a number of industrial processes such as in food, fermentation, textiles and paper industries. Plant sources had not been considered with enough significance as the source of these enzymes yet. More can be found at Creative Enzymes website.
B. cereus is a spore former. Spores are known for their very high heat resistant qualities.

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.

Bacteria like Escherichia coli and Bacillus subtilis are used to produce antibiotics, enzymes, and vaccines. Fungi like Aspergillus niger and Saccharomyces cerevisiae are utilized for producing food products like bread, beer, and cheese, as well as for manufacturing antibiotics and enzymes.
