| Abstract: | The polysaccharide producing soil alga Chlamydomonas mexicana Lewin was grown on soil surfaces in a growth chamber, with cell number and total polysaccharide measured weekly. Cell growth was pronounced, reaching an excess of 107 cells · cm?2 within one week. Polysaccharide production was also pronounced, with similar amounts of polysaccharide synthesized whether or not the cells were continuously given nutrients. Polysaccharide synthesis increased once the cells slowed in their growth, as in previous work with the cells in liquid medium. |
