In this study, the feasibility of biohydrogen production from enzymatic hydrolysis of food waste was investigated. Food waste (solid-to-liquid ratio of 10%, w/v) was first hydrolyzed by commercial glucoamylase to release glucose (24.35 g/L) in the food waste hydrolysate. Then, the obtained food waste hydrolysate was used as substrate for biohydrogen production in the batch and continuous (conti...

BACKGROUND A partially hydrolysed and dried product of pacific whiting fish is marketed as a health food supplement supporting 'intestinal health'. AIM To examine whether the partially hydrolysed and dried product of pacific whiting fish influenced the small intestinal damaging side effects of the nonsteroidal anti-inflammatory drug, indomethacin. METHODS Eight human volunteers completed a ...

Bacillus thuringiensis subsp. israelensis is the leading biopesticide in world due to its specificity and lack of toxicity. The use Bti still restricted developing countries bioprocess complications high cost production. In present study we have shown that lignocellulosic agro waste residues like rice straw can be used as effective substrates with appropriate chemical treatment methods. We comp...

Because of the generally more rapid amino acid absorption and lower osmotic pressure of small peptides compared with free amino acids, it has been suggested that 'elemental' diets should contain both small peptides and free amino acids as the nitrogen source. While studying protein hydrolysates intended for use in such diets we observed surprising differences in the absorption of amino acids, w...

In this study, Halomonas boliviensis was cultivated on bakery waste hydrolysate and seawater in batch and fed-batch cultures for polyhydroxybutyrate (PHB) production. Results demonstrated that bakery waste hydrolysate and seawater could be efficiently utilized by Halomonas boliviensis while PHB contents between 10 and 30% (w/w) were obtained. Furthermore, three methods for bakery waste hydrolys...

Fish collagen is reported with an increased bioavailability as compared to other sources, the extraction being performed on secondary sources skin, bones, scales, or fins resulted after fish processing. The aim of present study was obtain biocompatible hydrolysates from waste Cyprinus carpio main aquaculture species in Romania using inexpensive and “green” neutral hydrolysis process. Neutral pr...

Rapeseed meal and waste molasses are two important agro-industrial by-products which are produced in large quantities. In this study, solid state fermentation and fungal autolysis were performed to produce rapeseed meal hydrolysate (RMH) using fungal strains of Aspergillus oryzae, Penicillium oxalicum and Neurospora crassa. The hydrolysate was used as fermentation feedstock for heterotrophic gr...
