Citrate Stimulates Oligosaccharide Synthesis in Metabolically Engineered Agrobacterium sp.

08-02-2011 | Anne M. Ruffing, Rachel Ruizhen Chen, Applied Biochemistry and Biotechnology, 2011

Agrobacterium sp. ATCC 31749 was previously shown to be an advantageous host for oligosaccharide production. Unexpectedly, the addition of citrate to the oligosaccharide synthesis reaction resulted in up to a sixfold improvement in the production N-aceytl-lactosamine, a disaccharide. The ...

Protein Refolding by N-Alkylpyridinium and N-Alkyl-N-methylpyrrolidinium Ionic Liquids

08-02-2011 | Etsushi Yamamoto, Satoshi Yamaguchi, Teruyuki Nagamune, Applied Biochemistry and Biotechnology, 2011

An important property of ionic liquids consisting of cations and anions is that the chemical structures can be easily tuned. To expand the repertoire of effective ionic liquid-based refolding additives, we focused on this tunable property and investigated the effects of new candidates such as ...

Determination of Methyl Parathion in Water and Its Removal on Zirconia Using Optical Enzyme Assay

01-02-2011 | Kanchanmala Deshpande, Rupesh K. Mishra, Sunil Bhand, Applied Biochemistry and Biotechnology, 2011

A simple, miniaturized microplate chemiluminescence assay for determination of methyl parathion (MP) was developed in 384-microwell plates. Zirconia (ZrO2) was added in microwell for adsorption of acetylcholinesterase (AChE). The developed assay is based on inhibition of AChE by MP. A good ...
