摘要: 本文研究了NaCl胁迫下,自养和混养小球藻的生长特性以及类胡萝卜素、蛋白质、多糖、脯氨酸和MDA的积累量。结果表明,在NaCl胁迫下,混养小球藻的生物量、细胞内多糖和MDA含量都明显高于自养小球藻,其类胡萝卜素含量、细胞内蛋白质含量和脯氨酸含量都明显低于自养小球藻。说明自养和混养小球藻都具有一定的抵抗盐胁迫的能力,但两者抵抗盐胁迫的表现形式各有差异。

关键词: 小球藻, 自养, 混养, 盐胁迫

Abstract: Accumulation of carotenoid, cell protein, polysaccharose and proline in autotrophy or polyculture Chlorella vulgaris as well as its growth characteristics under NaCl stress were studied in this paper. The results indicated that the content of biomass, polysaccharose and MDA for polyculture Chlorella vulgaris was significantly superior to that for autotrophy Chlorella vulgaris, while the content of carotenoid, cell protein and proline content was significantly inferior to that for autotrophy Chlorella vulgaris, which illustrated that autotrophy and polyculture Chlorella vulgaris both had certain resistance to salt stress, but the pattern manifestation to resist salt stress was different between each other.

Key words: Chlorella vulgaris, autotrophy, polyculture, salt stress
