Improved toluidine blue-DNA agar for detection of DNA hydrolysis by campylobacters

Improved toluidine blue-DNA agar for detection of DNA hydrolysis by campylobacters.

Our improved toluidine blue-DNA agar was compared with methyl green DNase test agar for the detection of DNA hydrolysis by campylobacters. The toluidine blue-DNA agar gave clear-cut positive and negative reactions with campylobacter strains belonging to several species.

Isolation of Serratia marcescens on deoxyribonuclease-toluidine blue-cephalothin agar.

Serratia marcescens was isolated on a new medium-commercial deoxyribonuclease agar with the addition of cephalothin (1,000 mug/ml) and Toluidine Blue (1,000 mug/ml). It was detected in water samples even though it comprised only 0.1 to 0.0001% of the total bacterial population.

A novel optical DNA biosensor for detection of trace concentration of Methylene blue using Gold nano-particles and Guanine rich single strand DNA

The glass surface modification with 3-(mercaptopropyl) trimethoxysilane (MPTS), gold nano-particles (GN) and guanine rich single strand DNA (ss-DNA) was utilized as a novel and efficient platform for sensing trace concentration of methylene blue (MB) by an inexpensive spectrophotometric method. Methylene Blue (MB) can interact with the guanine base of single strand DNA and absorbed onto glass s...
