The Feed Additive "Bio-omegaxanthin": A Technology and Business Feasibility Study
Abstract:
Crude glyceral is the primary by-product form biodiesel production. As the biodiesel
production is increasing exponentially, the crude glyceral has also been generated in a large
quantity. Even though pure glyceral is widely applied in health, cosmatics and many other
industries, it is too costly to be purified into to higher quality products. Therefore, the
innovative utilizations of crude glyceral from biodiesel production are sought. Both
Schizochytrium limacinum and Phaffia rhodozyma are capable of utilizing crude glyceral as
carbon source for growth and producing valuable metabolites, DHA and astaxanthin,
respectively. Since optimum conditions as well as compositions of culture medium of these
microorganisms are quite similar thus, the objective of this study is to study the technology
and business feasibility for producing animal feed additive "Bio-omegaxanthin" from
mixed culture of P. rhodozyma and S. limacinum using crude glyceral from biodiesel
production as a sole carbon source. Results showed that Bio-omegaxanthin production
process is not complicated whilst instruments as well as technology required for
Bio-omegaxanthin production is also available in Thailand. Moreover, the global demand
both of astaxanthin and DHA are continuously increasing at a high rate annually. Financial
analysis showed Bio-omegaxanthin project will generate 162,931,787 bath benefit with the
profitability rate of 19% and the time taken to recover the initial investment cost is 8 years
and 6 months. Therefore, production of Bio-omegaxanthin intended for animal feed
addition is considered feasible both technologically and commercially.
