Abstract
Some species of extremely halophilic archaebacteria, Halobacteriaceae, have been shown to accumulate large amounts of poly (beta-hydroxybutyrate) under conditions of nitrogen limitation and abundant carbon source. The production of poly (beta-hydroxybutyrate), at least in large quantities, was restricted to two carbohydrate-utilizing species, Halobacterium mediterranei and H. volcanii. In addition to the nutrients in the media, the salt concentration also influenced poly (beta-hydroxybutyrate) accumulation, which was greater at lower salt concentrations. The possible application of these microorganisms for the production of biodegradable plastics is discussed.
摘要
某些极端嗜盐古菌，如盐杆菌科（Halobacteriaceae），在氮源限制和丰富碳源的条件下会大量积累聚-β-羟基丁酸（poly (beta-hydroxybutyrate)）。至少在大量生产方面，聚-β-羟基丁酸的生产仅限于两种利用碳水化合物的物种，即地中海盐杆菌（Halobacterium mediterranei）和 V 型盐杆菌（H. volcanii）。除了培养基中的营养物质外，盐浓度也会影响聚-β-羟基丁酸的积累，在较低盐浓度下积累量更大。讨论了这些微生物在生产可生物降解塑料方面的可能应用。
