Abstract:

The thermophilic Geobacillus caldoxylosilyticus strain J16 was isolated after screening many microorganisms. Its factors was thermophilic，but could not degrade cellulose. It was significance for paper industry and renewable energy industry. The factors were studied, which effected on lignin peroxidase and manganese peroxidase. The strain could grow very well at 65℃ and pH4.0. When fermented with the agriculture wastes about soybean stem, maize stem, rape stem, sawdust, wheat stem and sesame stem, it could efficiently degrade lignin up to 7.5%, but not degrade cellulose. All of above showed that it was significant for paper industry and renewable energy industry. All the data showed that this strain could be applied to agriculture wastes and Sewage, and it was very important for environmental protection.
