Killing of Bacullus spores by aqueous dissolved oxygen, ascorbic acid, and copper ions

Article Abstract:

This article describes the mechanism of action of a modified Fenton reagent formulation consisting of cupric chloride, ascorbic acid, and sodium chloride, which acts as an effective bacterial sporicide under aerobic conditions. Data show that the reaction involves conversion of aqueous dissolved oxygen to hydrogen peroxide by copper ionic catalyst followed by hydroxyl radicals formation, which kills the spores.

Curvularia haloperoxidase: antimicrobial activity and potential application as a surface desinfectant

Article Abstract:

The authors have examined the antimicrobial enzyme system Curvularia haloperoxidase. The aim of the investigation has been to evaluate the potential of this system as a sanitizing agent which facilitates the oxidation of halides to antimicrobial compounds in the presence of hydrogen peroxide.

Novel eukaryotic lineages inferred from small-subunit rRNA analyses of oxygen-depleted marine environments

Article Abstract:

Research has been conducted on microeukaryotes from oxygen-depleted environments. The authors describe their cultivation-independent small-subunit rRNA-based study of these microeukaryotes, and suggest that oxygen-depleted environments harbor diverse organism comminities.
