Applications of Immobilized Microbial Cells

Cofactor Regeneration for Enzyme-Catalysed Synthesis

“…Enzymatic phosphorylation of RNA (extracted from yeast, US Biochemical Corp.) or fermentation produces nucleoside phosphates. Many reports describe the production of nucleoside phosphates by enzymatic methods (Langer et al, 1976;Samejima et al, 1978b;Yang and Colton, 1982;Crans and Whitesides, 1983;Kondo etal., 1984;Nakajima et al ., 1984;Crans et al, 1988) or by fermentation (reviews and leading references: Tanaka etal., 1968;Hirose, Enei and Shibai, 1979;Samejima Kimura and Ado, 1980;Asada etal., 1981a, b;Kimura et al, 1981;Fujio andFuruya, 1983, 1985;Linko and Linko, 1983;Kondo et al, 1984;Yamaguchi et al, 1984;Chibata, Tosa and Sato, 1985.;Yonehara and Tani, 1987). Several simple methods, applicable on a laboratory scale, produce mixtures of nucleotides by the enzymatic hydrolysis of yeast RNA (Leuchs etal., 1979;Wong, Haynie and Whitesides, 1983).…”

Suitability of Immobilized Pseudomonas fluorescens SM1 Strain for Remediation of Phenols, Heavy Metals, and Pesticides from Water

“…Bioremediation processes involving immobilized microbial cells have attracted a lot of attention during the last couple of decades owing to their greater potential to degrade the wastes compared with the conventional systems (Linko and Linko 1983;Heitkamp et al 1990;Ignatov et al 2002).…”

Carbohydrases

“…The enzyme lactase acts as a /?-galactosidase and hydrolyzes this sugar to glucose and galactose, two monosaccharides that are sweeter (Table III), more digestible, and more soluble than lactose (Shukla, 1975;Klostermeyer et al, 1978;Severinsen et al, 1979;Barker and Shirley, 1980;Coughlan and Charles, 1980;Fox, 1980;Miller and Brand, 1980;Ahn and Kim, 1981;Linko and Linko, 1983;Gekas and Lopez-Leiva, 1985;Mahoney, 1985;Gerhartz, 1990).…”
