A novel pathway producing dimethylsulphide in bacteria is widespread in soil environments.

Nat. Commun. 6 , 6579, (2015)

The volatile compound dimethylsulphide (DMS) is important in climate regulation, the sulphur cycle and signalling to higher organisms. Microbial catabolism of the marine osmolyte dimethylsulphonioprop...

Microfluidics-based in situ padlock/rolling circle amplification system for counting single DNA molecules in a cell.

Anal. Sci. 30(12) , 1107-12, (2014)

In situ padlock/rolling circle amplification (RCA) is a method used to amplify, visualize, and quantify target DNA molecules in cells. However, the multiple reaction steps involved make this technique...

Combined effects of drying methods, extract concentration, and film thickness on efficacy of antimicrobial chitosan films.

J. Food Sci. 79(6) , E1150-8, (2014)

An idea of using a suitable drying method to minimize the loss of added antimicrobial agent and, at the same time, to modify the structure, and hence the release characteristics of chitosan films was ...
