Responses of a thermophilic Synechococcus isolate from the microbial mat of Octopus Spring to light

Article Abstract:

An isolate of Synechococcus OS-B Octopus Spring microbial mats was used for evaluating the response of thermophilic cyanobacteria in microbial mats to fluctuating environmental parameters. Findings reveal that high light (HL) caused reduced levels of transcripts encoding phycobilisome components and an enhanced transcript abundance of genes encoding terminal oxidases, superoxide dismutase, tocopherol cyclase and phytoenne desaturase.

Mass transport of macromolecules within an in vitro model of supragingival plaque

Article Abstract:

Research examines the diffusion of carbohydrates into supragingival plaque and of metabolites within the natural dental plaques or biofilms into the exterior environment using artificially generated polyspecies biofilms impregnated with oral bacteria. Data indicate that the rate of diffusion of the probes is constant, regardless of the biofilm depth.

Effect of phosphorus on survival of Escherichia coli in drinking water biofilms

Article Abstract:

The effects of phosphorus on the survival of Escherichia coli in an experimental drinking water system and biofilms are investigated. Extremely high concentrations of phosphorus concentrations are found to prolong the survival of culturable E. coli in water, as well as biofilms.
