Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A novel material (hybrid immobilization material, HY‐IM) was developed by the combination of calcium‐alginate, activated carbon (prepared from de‐oiled jatropha waste), wako gel (silica gel) and chitosan for immobilization of hydrogen‐producing bacteria. The stability of the prepared immobilized cells was evaluated by ten repetitive batch experimental runs; the cumulative hydrogen production from beverage wastewater during ten runs was in the range of 2865 to 3300 mL H₂/L. The Scanning electron microscopy (SEM) images of the HY‐IM showed bacterial cells entrapment. The hydrogen production performance of the reactor with HY‐IM (1.12 ± 0.04 mol H₂/mol hexose_utilized) was comparable to suspended cells reactor (1.07 ± 0.01 mol H₂/mol hexose_utilized), and demonstrated repeated usage of same HY‐IM in the reactor with high stability. Experimental evidence suggests that HY‐IM can be applied in continuous biohydrogen production from industrial wastewaters with high efficiency and stability.</p> </abstract>
