Bio-refinery based on oilseed meals for sustainable bio-diesel industry
Oilseeds were widely applied to produce bio-diesel instead of petroleum. With the development of bio-diesel and consumption of the limited petroleum resources, amounts of oilseed meals came into being and caused our environmental pollution. Rapeseed is one of most important edible oil resource in worldwide, and is applied for bio-diesel in many countries. However, rapeseed meal is restricted to feedstuff and fertilizer because of containing toxic components. In this paper, rapeseed meals were fermented by Bacillus subtilis in order to uprate their value. Nattokinase (NK), polyglutamic acid (PGA) and peptides were obtained by developed high efficient conversion and separation techniques. The results showed that the protein content of peptides (MW＜5000) after ultrafiltration were 70.13％, and two parts of peptides were separated and purified by Sephadex G-25 gel filtration chromatography. The fibrinolytic activity of crude SK was 83.32IU/mg. Meanwhile, toxic components, such as glucosinolates, isothiocyanates, oxazolidone, were degraded after fermentation. Moreover, rapeseed meals could be modified to obtain biodegradable protein-plastic. In our research, functional and active bio-components were gained by biorefinery approaches, which could improve economic and useful value of rapeseed meals greatly. This would provide an elective avenue for the sustainable development of bio-diesel industry in future.
