Transglycosylating β‐d‐galactosidase and α‐l‐fucosidase from Paenibacillus sp. 3179 from a hot spring in East Greenland
Abstract Thermal springs are excellent locations for discovery of thermostable microorganisms and enzymes. In this study, we identify a novel thermotolerant bacterial strain related to Paenibacillus dendritiformis , denoted Paenibacillus sp. 3179, which was isolated from a thermal spring in East Gre...
