在海洋环境中的酵母菌分布与多样性

Distribution and Diversity of Yeasts from Marine Evironment

最近几年作者对不同海洋环境中的酵母资源、分布和多样性进行的大量研究,从中发现了22属63种1051株。并且发现这些广泛分布在海水、海泥、高盐海水、深海、各种大型海藻表面、各种海鱼体表和体内和红树林生态系统中。不同种的酵母可以产生蛋白酶、脂酶、植酸酶、菊糖酶、纤维素酶、β-1,3-葡聚酶、嗜杀因子、核黄素、铁载体等活性产物,所以这些酵母菌具有广泛的实际用途。

In recent years, yeast bioresources, distribution and biodiversity in different marine environments have been extensively investigated by our research group. A total of 1 051 yeast strains belonging to 22 genera and 63 species were identified by routine and molecular identification. We found that the yeasts are widely distributed in seawater, sediments, salterns, deep sea, surface of different species of marine algae, different species of marine fish and mangrove ecosystems. It was also found that protease, phytase, inulinase, lipase, cellulase, β-1, 3-glucanase, killer toxin, riboflavin and siderophores can be produced by different yeast strains. Therefore, the yeast strains have many potential applications.
