Substrate-dependent production and some properties of a thermostable, α-galactosidase from Rhodothermus marinus

Blücher, Anna ; Karlsson, Eva Nordberg LU orcid and Holst, Olle LU (2000) In Biotechnology Letters 22(8). p.663-669
Abstract

α-Galactosidase activity in Rhodothermus marinus is dependent on the composition of the growth media. A maximum of 46 μU g-1 cell dry weight was obtained using minimal medium with galactooligo- or polysaccharides as single carbon source. An enzyme hydrolysing both high and low molecular weight galacto-saccharides was partly purified from the cell fractions. The molecular weight was 200 kDa (native) and 50 kDa (monomer). It was optimally active at 85°C, with a half-life of 2 h at 75°C, and had a broad pH range (4-8).
