Preservation of microorganisms

Advances in preservation methods: keeping biosensor microorganisms alive and active.

The ability of bacteria to sense their surroundings can be employed to measure the bioavailability and toxicity of pollutants. However, long-term maintenance of both viability and activity of the sensor bacteria is required for the development of cell-based devices for environmental monitoring. To meet these demands, various techniques to conserve such bacteria have been reported, including fre...

Impact of biomineralization on the preservation of microorganisms during fossilization: An experimental perspective

Evaluation of the presence of microorganisms in solid-organ preservation solution.

OBJECTIVE To assess the presence of microorganism contamination in the preservation solution for transplant organs (kidney/pancreas). METHOD Between August 2007 and March 2008, 136 samples of preservation solution were studied prior to graft implantation. Variables related to the donor and to the presence of microorganisms in the preservation solution of organs were evaluated, after which the...

Emerging Preservation Techniques for Controlling Spoilage and Pathogenic Microorganisms in Fruit Juices

Fruit juices are important commodities in the global market providing vast possibilities for new value added products to meet consumer demand for convenience, nutrition, and health. Fruit juices are spoiled primarily due to proliferation of acid tolerant and osmophilic microflora. There is also risk of food borne microbial infections which is associated with the consumption of fruit juices. In ...
