The gene encoding levansucrase (LVS) from Bacillus amyloliquefaciens (sacB[BamP]) was isolated, sequenced and expressed in Bacillus subtilis. Analysis of the nucleotide sequence of sacB[BamP] reveals extensive homology with that of the B. subtilis LVS-encoding gene in the promoter and coding region. The sacB[BamP] gene cloned in a multicopy plasmid is(More)
The adsorption characteristics of Cd(II) from electrolytic solution by activated charcoal have been investigated. It was found that the amount of adsorption of Cd(II) depends mainly on the pH value of the solution, the number of added inorganic ions, and oxygen-containing groups on the surface. The activated charcoal was treated with the oxidation-negative(More)
Spotlight summary: Light sources have an indispensable role in everyday life. From the first lamp using animal fat around 70,000 BC, to modern light sources, these have been widely used and developed for diverse applications going much beyond night lighting. For example, light-emitting diodes (LEDs) have been extensively utilized in illumination, e.g. as(More)
