    Production of Xylanase by Streptomyces viridosporus T7A by Solid-State Fermentation in Semi Pilot Scale

  • Original language description

    Annually in Brazil, the agro-industrial sector produces tones of lignocellulosicssubstances, which are partially used as animal feed the other part became environmentalconcern. The use of enzymes as feed additives is well established. The main objectiveofpresent work was to use lignocellulosic residues to produce xylanase from Streptomycesviridosporus T7A in different types of semi pilot bioreactors Experiments were conductedusing a mixture of sugar cane bagasse (70%), napier grass (20%) and defatted soybean cake(10%). A nutritive solution containing Na2HPO4 0.064 g.g-1 DM was added and the initialhumidity controlled to 85%, and pH 8.5. Two types of semi pilot bioreactors were tested:perforated trays and horizontal drum bioreactors. The results showedeconomic advantageof the perforated trays, because that xylanase production is not dependent of aeration. Theresultant fermented material could be certainly used in animal feed.

    Produkce xylanasy pomocí fermentace na pevném substrátě s Streptomyces viridosporus T7A v poloprovozním měřítku

  • Czech description

    Každoročně je v Brazílii vyprodukováno několik tun lignocelulasových složek, které jsou na jedné straně využity jako krmivo pro zvířata, ale stavají se hrozbou pro životní prostředí. Hlavním cílem této práce bylo využít lignocelulosové zbytky k produkcixylanasy za použití Streptomyces viridosporus T7A v různých typech bioreaktorů. Byla využita směs cukrové třtiny bagasse, duchnu čerbeného a sojových bobů, které byly zbaveny tuku. Byly testovány dva typy bioreaktorů. Perforované rošty a horizontální bubnové reaktory. Ekonomicky výhodné se ukázaly být perforované rošty.
