Investigation of Haematococcus Pluvialis for Microalgae Cultivation Using the Flashing Light Method

Öz

In view of factors such as their suitability for biofuel production, high oil content, easy accessibility and resistance to contamination, Haematococcus pluvialis species of Chlorophyta class was the choice of microalgae selected for this study. Time-based voltage, voltage-based light intensity calibration study and the amount of increase in cell concentration in time have been specified using the flashing method for the examined species. As a result of voltage calibration studies conducted under the trial method, light intensity for flashing practice was detected as 850 µE.m-2s-1. In order to apply light intensity continuously and at an equivalent level, a FMT-150 photobioreactor was employed and on the first day when the microalgae species was introduced into the photobioreactor, a cell count of 350 mg.ml-1 was obtained. The growth process was examined through the cell counts carried out every 48 hours, including the initial phase, under a constant temperature of 25oC. Having applied all these parameters, the Haematococcus pluvialis species, which had a cell concentration of 350 mg.ml-1, displayed a tendency to grow until the end of the 32th day. While the highest number of cells was reached on the 32nd day with 565 mg.ml-1, the population started to decline after the 32nd day, and the trial was terminated on the 38th day.
