Mass cultivation of Tetraselmis tetrathele using of mollas and beer wastewater to evaluate growth viability and fatty acids composition Fatemeh Sharifi Kheyrabadi fatemehsharifi479@yahoo com December 5 2018 Department of Natural Resources Isfahan University of Technology Isfahan 84156 83111 Iran Language PersianDegree MScDr Omidvar Farhadian omfarhad@cc iut ac irAbstractThe wastewaters have different nutrients that could be applied as rich culture media for algalcultivation The marine green microalga Tetraselmis tetrathele is one of the important species inthe marine aquaculture activities In this research the growth viability proximate and fatty acidscomposition were evaluated by cultivation of T tetrathele on mollas and beer waste water in lowand high concentrations The experiment ran with six different treatments low and high Conway LC HC low and high mollas LM HM and low and high beer LB HB for 11 days Resultsshowed that this algae can be cultured on raw beer and mollas waste waters but the highest celldensity 96 7 103 cell ml was in the HM treatment and maximum SGR 15 5 day were obtainedin the LC treatment The cell viability in the T tetrathele cultured on HB treatment had the highestpercentage Up to 100 compared to other treatments The protein and lipid contents were thehighest in the HB while the carbohydrate was the highest in the LM treatment The protein lipidand carbohydrate ranged as 10 70 39 5 2 98 8 14 and 5 98 28 92 respectively Based on fattyacids composition the content of SAFA MUFA and PUFA were 45 24 37 8 and 16 94 in HC 21 38 38 38 and 40 21 in LC 42 3 32 39 and 25 29 in HB 42 6 40 28 and 17 1 in LB also 27 44 50 53 and 22 02 in HB 47 19 30 11 and 22 68 in LB In addition the total content of n 3 and n 6were obtained as 2 12 and 15 08 for HC 20 26 and 19 95 for LC for HB 12 98 and 12 31 for LB2 42 and 14 68 and for HM 2 11 and 19 91 for LM 5 33 and 17 35 Furthermore the highestSAFA MUFA and PUFA were measured in the treatments of LM HM and LC treatment respectively Of the SAFA MUFA and PUFA the fatty acids of C16 0 C18 1 and C18 2n 6 werehighest respectively The ratio of n 3 n 6 was highest in the high beer treatment The findings ofthis study showed that beer and mollas wastewaters could be suitable for the media production ofT tetraselmis algae with a suitable fatty acid profile Keywords Beer Fatty acid Growth Microalga Mollas Tetraselmis tetrathele Viability
