A genus Trentepohlia is the major type of filamentous subaerial green alga that grows in tropical zones. Its species have a yellow to red colour because of a large amount of total carotenoids. Trentepohlia monilia, a dominant Trentepohlia species, was investigated during the winter season at 720 metres above sea level in the Chiang Dao Wildlife Sanctuary, Chiang Mai Province, in northern Thailand. Growth of the species in different liquid culture media was measured to find the best such medium, and various factors in the media were measured to determine which ones resulted in the highest amount of total carotenoids. The results showed that the enriched seawater medium (ESM) liquid culture produced the maximum growth of the species in week 9 of the study and also produced the highest total carotenoid content. A pH of 7.0, with an added peptone of 1%, culture strength of 50%, nitrogen source of -0.50 times and vitamin B12 source of -0.50 times the usual concentration in the ESM generated the optimum conditions for growing T. monilia and also produced a total carotenoid content that was higher than the total chlorophyll content. This level of growth could make the species a future source of carotenoids for industrial products. [ABSTRACT FROM AUTHOR] |
