AbstractThe effects of temperature and light on the growth and geosmin production of Lyngbya kuetzingii were determined. Of the three temperatures tested, 10, 25 and 35A degrees C, the maximal geosmin concentration and geosmin productivity were yielded at 10A degrees C, while the highest chl a production was observed at 25A degrees C. In the studies on light intensity, the maximal geosmin concentration and geosmin productivity were observed at 10 mu mol m(-2) s(-1), while the highest chl a production was at 20 mu mol m(-2) s(-1). It was suggested that more geosmin was synthesized with lower chl a demand. Meanwhile, the relative amounts of extra- and intracellular geosmin were investigated. Under optimum growth conditions (20 mu mol m(-2) s(-1), 25A degrees C; BG-11 medium), the amounts of extracellular geosmin increased as the growth progressed and reached the maximum in the stationary phase, while the intracellular geosmin reached its maximum value in the late exponential phase, and then began to decline. However, under the low temperature (10A degrees C) or light (10 mu mol m(-2) s(-1)) conditions, more intracellular geosmin was synthesized and mainly accumulated in the cells. The proportions of extracellular geosmin were high, to 33.33 and 32.27%, respectively, during the stationary phase at 35A degrees C and 20 mu mol m(-2) s(-1). It was indicated that low temperature or light could stimulate geosmin production and favor the accumulation of geosmin in cells, while more intracellular geosmin may be released into the medium at higher temperatures or optimum light intensity.; The effects of temperature and light on the growth and geosmin production of Lyngbya kuetzingii were determined.
