Industrial Fermentation Strains
Aspergillus Niger
Aspergillus niger is a common fungal species in the genus Aspergillus, widely distributed in grain, plant-derived products, and soils around the world. It is an important industrial fermentation strain capable of producing amylase, acid protease, cellulase, pectinase, glucose oxidase, citric acid, gluconic acid, and gallic acid. Certain strains can also convert hydroxylated steroid compounds into androgens. Its optimum growth temperature is 98.6°F (37°C), and the minimum relative humidity required is 88%. It can cause mold spoilage in high-moisture grain and other industrial materials.
In the food industry, it is used as a fermentation microorganism in vinegar koji production, bran koji liquor production, citric acid fermentation, and other processes, mainly due to its ability to secrete amylase, saccharifying enzymes, citric acid, gluconic acid, and gallic acid. In the biofertilizer industry, Aspergillus niger can decompose macromolecular organic matter and insoluble inorganic substances, making nutrients easier for crops to absorb and utilize, improving soil structure, enhancing soil fertility, and increasing crop yield.
Applications:
Potential hazards:
Under high-temperature and high-humidity conditions, Aspergillus niger can proliferate rapidly, produce enzymes and heat, and cause spoilage. In cotton, it may lead to flower drop or boll rot; in succulent fruits, it may cause rot or soft rot; on onion scales, it may produce large amounts of black powdery spores; and during the rainy season, it may also cause mildew on clothing and other materials.
Aspergillus Oryzae
Aspergillus Oryzae is a common fungal species in the genus Aspergillus. It is a strain known for producing compound enzyme systems. In addition to protease, it can also produce amylase, saccharifying enzymes, cellulase, phytase, and other enzymes.
