Culture conditions, biochemical analysis and determination of heavy metal biosorption of Tetracystis isobilateralis R.M. Brown and H.C. Bold (Chlorococcales)

One of the most important reasons why commercial microalgae production is so limited, effects microalgae an biotechnology, even though the earth has a rich microalgae flora. Determination of new microalgae, wich have commercial importance will help to develope this field. By this study it's wanted to hasten the studies, made on this field.Tetracystis isobilateralis R.M. Brown & H.C. Bold (Cholorococcales) determined from the University of Ege, Microalgae Culture Collections are come out for culturel environment. Under the circumstances of the culture, enough biyomas has been gotten access for biochemical and nutriential analyses, which has been cultured. Total protein, oil, fatty acid types, A, E vitamines and ß -carroten have been researched. Three different consantrations of living cells against different heavy metals, salt belongs to cadmium, cobalt, lead, nickel and manganese elements applied for biosorption has been certained.It has been seen that they reached to the sizes 30,1x106 cell/ml consantration 0,462 gr/L biomass weight under microalgae OTM culture conditions, in 8,7 pH, 24+2 ºC and 500 mL/min. in aired culture condition. In biochemical and nutritional analyses it has been seen that it reached to the size; total protein 38,73%, total oil 16,37%, 301,8 mg/kg vitamineE, 28,40 mg/kg vitamineA and 815,4 mg/kg ß-caroten. It has been seen that fatty acides, Palonitic, Linoleic, Oleic, Stearic fatty acides have reached to 40,99%, 6,34%, 35,89%, 16,64%. We see that it absorbes mangan, which it absorbes the best in 46,5 mg/gr.Keywords: Tetracystis isobilateralis, microalgae, culture, nutrient, heavy metal
