چکیده | ||
The effects of temperature and pH on the growth and quantity of vital products extracted from the cyanobacterial species Anabaena oryzae in the ASM-1 culture media were studied. Three levels of temperature (18 ± 2 °C, 27 ± 2 °C and 30 ± 2°C) and pH (6.8, 7.6 and 8.4) were selected. It was found that the best daily growth and the largest amount of vital products occur at a temperature of 27 ± 2 ° C and pH 7.6. The vital products were diagnosed by a GC-MS device, and the results of the diagnosis have shown the presence of the compounds dihydroxyphenyl glycol, n -acetyl-Dglucosamine, linalool, niacinamide and gibberellins. | ||
