摘      要：In this study on the possiblities of microalgae technology as an option for CO2 mitiga-tion, many microalgae were isolated from seawater. Some species of the isolates, Chlamydomonas *** YA-SH-1, which accumulates starch in cells under light and ferment ethanol in dark and anaerobiccondition, was grown outdoors by using 50-L tubular bioreactors in batch cultivation and harvested. Usingthese cells, the performance of ethanol production was examined quantitatively in a 0.5-L scale fermen-tor. Another species, Tetraselmis sp. strain Tt-1, was cultivated in a semi-batch manner by a similar typeof tubular bioreactor indoors and examined for its utilization. Tests showed these cells could be used aspartial substitute for wood and kenaf pulp for processing into paper. With the idea of making microalgaeproduce cellulose by genetic engineering in their minds, the authors studied the structure of bacterial cel-lulose synthase genes and the low temperature-induced, reversible flocculation in a thermophilic bluegreen alga (Cyanobacterium), Synechocystis vulcanus in order to examine the feasibility of using thesegenes as gene source and the cynanobacterium as host.
