1. Production of α-Galactosidase by Aspergillus oryzae through solid-state fermentation and its application in soymilk Galactooligosaccharide hydrolysis
α-Galactosidase was produced by Aspergillus oryzae on red gram plant waste-wheat bran based media in solid-state fermentation (SSF). Optimum temperature for α-galactosidase production was 35 0C and upto 4 cm of bed height of substrate had no inhibitory effect on enzyme production. Hydrolysis of galactooligosaccharides in soymilk was carried out by α-galac

2. Produção de galactooligossacarideos por linhagens fungicas / Production of galactooligosaccharides by fungi strains
Actually, one of the most significant development in science are functional foods, connected with the development of dietetic supplement that affects beneficially the health. Among these, we can mention the galactooligosaccharides, that is a group of oligosaccharides considerated as non-digestible carbohydrates due to their resistance to hydrolysis of intest

3. Produção de galactooligossacarideo por lactase fungica. / Production by galactooligosaccharide for fungic lactase.
Os galactooligossacarídeos (GOS), um grupo de oligossacarídeos, são carboidratos não digeríveis (NDOs), resistentes à hidrólise das enzimas digestivas do intestino, tem os efeitos fisiológicos similares ao da fibra dietética. Sua ingestão aumenta a proliferação das Bifidobacterium e dos Lactobacilus no intestino. Eles são considerados como ingre

4. Production of galacto-oligosaccharide from lactose by Sterigmatomyces elviae CBS8119.
Our stock cultures were screened for microorganisms that can produce galacto-oligosaccharide (Gal-OS) from lactose. Of the 574 strains of bacteria and yeasts tested, Sterigmatomyces elviae CBS8119, Rhodotorula minuta IFO879, and Sirobasidium magnum CBS6803 were found to be efficient producers of Gal-OS from lactose and S. elviae CBS8119 was selected as a rep

5. Synthesis and Fermentation Properties of Novel Galacto-Oligosaccharides by β-Galactosidases from Bifidobacterium Species
β-Galactosidase enzymes were extracted from pure cultures of Bifidobacterium angulatum, B. bifidum BB-12, B. adolescentis ANB-7, B. infantis DSM-20088, and B. pseudolongum DSM-20099 and used in glycosyl transfer reactions to synthesize oligosaccharides from lactose. At a lactose concentration of 30% (wt/wt) oligosaccharide yields of 24.7 to 47.6% occurred w

6. Purification and properties of a novel thermostable galacto-oligosaccharide-producing beta-galactosidase from Sterigmatomyces elviae CBS8119.
A thermostable beta-galactosidase which catalyzed the production of galacto-oligosaccharide from lactose was solubilized from a cell wall preparation of Sterigmatomyces elviae CBS8119. The enzyme was purified to homogeneity by means of chromatography on DEAE-Toyopearl, Butyl-Toyopearl, Chromatofocusing, and p-aminobenzyl 1-thio-beta-D-galactopyranoside agaro

7. Molecular and Biochemical Analysis of Two β-Galactosidases from Bifidobacterium infantis HL96
Two genes encoding β-galactosidase isoenzymes, β-galI and β-galIII, from Bifidobacterium infantis HL96 were revealed on 3.6- and 2.4-kb DNA fragments, respectively, by nucleotide sequence analysis of the two fragments. β-galI (3,069 bp) encodes a 1,022-amino-acid (aa) polypeptide with a predicted molecular mass of 113 kDa. A putative ribosome binding sit
