1. 1. Alkaliphilic Bacillus species and an alkaline active lipolytic enzyme

   Författare :Virginia Vargas Calle; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; soda lakes; alkaliphilic Bacillus sp.; lipolytic enzyme; Bacillus bogoriensis; Bacillus halodurans; Bioteknik;

   Sammanfattning : The Great Rift Valley running through Eastern Africa contains a large number of soda lakes. These unique lakes constitute among the most stable alkaline environments with a dense and varied population of microorganisms. Such microorganisms are invariable alkaliphiles and are considered to be a promising source of enzymes with unique features. LÄS MER

3. 2. An Alkaline Active Cyclodextrin Glycosyltransferase from an Alkaliphilic Bacillus agaradhaerens

   Författare :Rita Martins; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloning; characterization; purification; 16S rRNA gene analysis; screening; alkaliphiles; soda lakes; Bacillus agaradhaerens; cyclodextrins; cyclodextrin glycosyltransferase; alpha-amylase family; sequencing; immobilization; Biotechnology; Bioteknik;

   Sammanfattning : Soda lakes represent the most stable naturally-occurring alkaline environments on Earth and harbour a diverse population of alkaliphiles. Alkaliphilic microorganisms have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values. LÄS MER

4. 3. An alkaline active maltooligosaccharide forming alpha-amylase from Bacillus halodurans

   Författare :Suhaila Hashim; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk teknik; Biochemical technology; differential scanning calorimetry; soda lakes; Bacillus halodurans; alkaliphile; á-amylase;

   Sammanfattning : The East African Rift Valley contains a number of soda lakes, which represent some of the most stable, naturally occurring alkaline environments on earth. Alkaliphilic microorganisms found in these habitats have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values for industrial applications.

5. 4. Molecular methods for microbial ecology : Developments, applications and results

   Författare :Lucas Sinclair; Alexander Eiler; Josh Neufeld; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; microbiology; metagenomics; ecology; metabolism; Bioinformatik; Bioinformatics;

   Sammanfattning : Recent developments in DNA sequencing technology allow the study of microbial ecology at unmatched detail. To fully embrace this revolution, an important avenue of research is the development of bioinformatic tools that enable scientists to leverage and manipulate the exceedingly large amounts of data produced.

7. 5. Impact of food quality on aquatic consumers : Behavioral and physiological adjustments

   Författare :Alfred Burian; Winder Monika; Kevin Flynn; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine Ecology; marin ekologi;

   Sammanfattning : Food quantity and quality together determine growth rates of consumers and the utilisation efficiencies of available resources in aquatic and terrestrial ecosystems. The effect of food quality on the performance of consumers is dependent on both, its direct influence on ingestion and assimilation rates, and on the behavioural and physiological adjustments of consumers to their food environment.
