求翻译：在光学显微镜下，其细胞特点为大部分为圆形，极少数为椭圆形，出芽生殖；其在各NaCl盐浓度上均具有一定的耐受性，其最佳生长NaCl盐浓度为3%。由此可确定其为海洋酵母菌。是什么意思？

Under an optical microscope, the cell characteristics for most of the round, very few oval budding; in nacl salt tolerated, with an optimum nacl salt concentration of 3%. Can be determined for marine yeast.

In the optical microscope, the cells are round for most features, and a few to be elliptical, insensitiveness reproduction; its concentration on the NaCl has a certain amount of resistance to its best growth NaCl salt concentration of 3 %. For this you can determine their marine yeast.
