Stripping specificity, microbial

Sodium chlorite has also been used for treatment and removal of toxic and odorous gases such as hydrogen sulfide and mercaptans. Chlorine dioxide from chlorite is also useful for microbial and slime control in paper mills and alkaline paper machine systems (164,165). The use of sodium chlorite in textile bleaching and stripping is well known. Cotton is not degraded by sodium chlorite because the oxidation reactions are specific for the hemiceUulose and lignin components of the fibers. 

As with any other analytical method, MCA s capacity is enhanced if it is easy to remove interfering compounds. Microbial adaptation confers specificity in binding unwanted compounds so they can be swept out without losing the sample for analysis. Figures 5a and 5b show the data for phenol and vanillic acid stripping under convenient conditions, namely, with easily acquired amounts of stripper cells (5 x 1010 cells), and conditions where interfering compound concentrations are relatively large, i.e., up to 10 times the amount of sample for analysis. 

The original methods have been modified to increase the accuracy of microbial phosphorus estimates on specific soils, and different protocols now exist for each step of the method (Table 7.2). Chloroform is most commonly used as fumigant, either gaseous, liquid or both. The non-carcinogenic hexa-nol is also effective as a fumigation biocide (McLaughlin et al., 1986) and must replace chloroform when certain brands of resin strips are used for extraction, since these are damaged by chloroform (Biinemann et al.,... 

The Antimicrobial I Panel did not provide a specific protocol for the assessment of the efficacy of products intended for this use but did suggest the incorporation of certain concepts in assessing product efficacy. The sampling procedures recommended are the cup scrubbing [25] or skin stripping techniques or any other appropriate techniques that allow accurate quantitation of the microbial flora at the test site. Any body site can be used but the genital area must be included. Clearly, the panel is concerned with notable differences of the microbial flora found in different parts of the human body.
