Summary: | Microbial cellulose is characteristic in that it has a much finer structure than plant cellulose and potential as a new material for various applications. However, because it is produced by culture approximately at 30℃, its production requires antifungal measures. Therefore, microbial cellulose-producing microorganisms were collected in Antarctica, an extremely cold region, and cultured at low temperatures. As a result, in Rhodotolura glacialis (No.3), Cryptococcus gastricus (No.4) and Cryptococcus victoriae (No.5), which were collected in Antarctica, the culture at 4℃ clearly formed pellicles. However, the culture at 30℃ did not form any pellicles, showing that this microbe was clearly psychrophilic. As mentioned above, psychrophilic microorganisms have made it possible to produce microbial cellulose in low-temperature culture, which is believed to have big industrial advantages.
