Ethanol production at 45°C by alginate-immobilized Kluyveromyces marxianus IMB3 during growth on lactose-containing media

Abstract: The thermotolerant yeast strain Kluyveromyces marxianus IMB3 was immobilized in calcium alginate and this was used in batch-fed reactor systems to convert lactose (4 g/l) to ethanol. Production of ethanol by the free and immobilized biocatalyst in the presence and absence of Mn2> was com pared. In systems containing the free microorganism in the presence and absence of Mn2>, ethanol increased to a maxi mum of 8 g/l within 40 hours with no significant difference in production by both systems. Ethanol production… Show more

“…were suspended in 100 mL 0.9% NaCl solution and then added into 100 mL sodium alginate solution. The mixture was added dropwise in 100 mL calcium chloride solution as has been described by Brady et al, (1997). The sodium alginate solution was created by diluting the sodium alginate powder in distilled water and the mixture was stirred overnight.…”
