Abstract:

 


Many
different wastewater and by-products derived from industrial activities
potentially support microalgal growth by providing a cost-effective and
sustainable solutions. In this present study, it
was aimed to biologically utilize cheese whey (CW) and corn steep liquor (CLS)
for microalgal biomass and lipid production by using these wastes in culture
media for heterotrophic microalga Crypthecodinium
cohnii cultivation. To determine nutrient
requirements for C. cohnii growing in
a medium prepared with CSL and in CW, statistical screening tools were used. CSL significantly enhanced microalgal growth
and it could be an alternative to yeast extract as the primary nutrient source.
As for CW, it served as a good culture medium for C. cohnii with the supplement of some of nutrients and eliminated the need for fresh water. Thus, a
new culture medium was developed by combining undiluted CW and CSL and optimized for the growth of
C. cohnii. Lastly, in a scale-up
attempt by using this new medium, microalgal production was performed in a 3 L
stirred tank bioreactor. C. cohnii
yielded relatively high biomass productivity (2.28 g/L.d) and lipid content
(28.7% dry weight) in the optimized medium. Althoug C. cohnii was known for its ability to accumulate high amounts of
docosahexaenoic acid (DHA), it transformed its fatty acid composition to an increased
proportion of saturated and monounsaturated fatty acids (C16:0-C18:1) that comprise
~70% of total fatty acids (TFA) when it was
cultivated in CW mainly supplemented with CSL. Thus, C. cohnii seemed to be
more feasible for biodiesel production than any other purposes when it was
cultivated in this new medium.
