The use of cold-active enzymes has many advantages, including reduced energy consumption and easy inactivation. ikaite columns SW Greenland are permanently cold (4-6°C) alkaline (above pH 10), the microorganisms living there their adapted to these conditions. Since only a small fraction total microbial diversity can be cultured in laboratory, combined approach involving functional screening strain collection metagenomic library was undertaken for discovery novel from columns. A with 322...
The submarine ikaite columns located in the Ikka Fjord Southern Greenland represent a unique, permanently cold (less than 6°C) and alkaline (above pH 10) environment are home to microbial community adapted these extreme conditions. bacterial archaeal inhabiting surrounding fjord was characterised by high-throughput pyrosequencing of 16S rRNA genes. Analysis structure revealed presence diverse community, both column interior at surface, very few archaea. A clear difference overall taxonomic...

Summary Proteases active at low temperature or high pH are used in many commercial applications, including the detergent, food and feed industries, bacteria specifically adapted to these conditions a potential source of novel proteases. Environments combining two extremes very rare, but offer promise proteases ideally suited work both temperature. In this report, from cold alkaline environments, ikaite columns Greenland ponds McMurdo Dry Valley region, Antarctica, were screened for...
Here we show that a commercial blocking reagent (G2) based on modified eukaryotic DNA significantly improved extraction efficiency. We subjected G2 to an inter-laboratory testing, where was extracted from the same clay subsoil using batch of kits. The campaign revealed large variation among participating laboratories, but increased number PCR-amplified16S rRNA genes recovered biomass naturally present in soils by one log unit. An extensive sequencing approach demonstrated free contaminating...
The ikaite columns in the Ikka Fjord Greenland represent one of few permanently cold and alkaline environments on Earth, interior is home to a bacterial community adapted these extreme conditions. characterized by low cell numbers imbedded calcium carbonate matrix, making extraction cells DNA challenge limiting molecular genomic studies this environment. To utilize genetic resource, cultivation at high pH temperature was studied as method for obtaining biomass from fraction that would not...
β-Galactosidases catalyse the hydrolysis of lactose into galactose and glucose; as an alternative reaction, some β-galactosidases also formation galactooligosaccharides by transglycosylation. Both reactions have industrial importance: is used to produce lactose-free milk, while been shown act prebiotics. For multi-domain β-galactosidases, hydrolysis/transglycosylation ratio can be modified truncation carbohydrate-binding modules. Here, analysis BbgIII, a multidomain β-galactosidase from...
