Περίληψη: | Alternative sugar beet pulp (SBP) refining strategies were evaluated to identify the most efficient process combining pectin extraction and poly(3-hydroxybutyrate) (PHB) production. The chosen process involved the consecutive aqueous separation of free sugars and extraction of a pectin-rich fraction before hydrothermal treatment and enzymatic hydrolysis of remaining solids. The optimal refining strategy resulted in the highest yield of pectin-rich extract (28% w/w) with 67% galacturonic acid content, 26% emulsifying stability and 0.15 m2/g activity index, with promising emulsifying application potential. Optimal enzymatic hydrolysis of remaining pectin-free solids led to 80.7% (w/w) overall glucan conversion yield, while the overall hemicellulose hydrolysis yield was 4.8% as most hemicellulose was contained in the pectin-rich extract. Bioreactor cultivation by Paraburkholderia sacchari with SBP derived sugars led to 62.2 g/L PHB with 53.1% (w/w) PHB content, 0.27 g/g yield and 1.7 g/(L·h) productivity, demonstrating a high efficiency in PHB production. In the integrated biorefinery scenario, 1 kg SBP could be converted into 252.9 g pectin-rich extract and 110.7 g PHB. The produced PHB could be employed for the formulation of bio-based and biodegradable food packaging, which when combined with pectin applications creates the opportunity to restructure the conventional sugar industry into a sustainable biorefinery. |
