    Notes: Abstract Employing a mineral salts medium containing Tween 80 as the primary carbon source, a strain of Bacillus stearothermophilus was isolated which was able to hydrolyse selected second and third-generation pyrethroids to non-insecticidal products. Of a range of pyrethroid insecticides the trans-isomer of permethrin was the most readily transformed by this microbial isolate, whilst flumethrin was the least. 3-Phenoxybenzoic acid and the respective halovinyl or haloacid moieties were detected as the major hydrolytic products of the pyrethroids. It is believed that 3-phenoxybenzoic acid was formed from 3-phenoxybenzyl alcohol which was not however detected as an intermediate in these systems. 3-Phenoxybenzoic acid was further transformed to 4-hydroxy-3-phenoxybenzoic acid. A potential metabolic pathway has been described.

    R-phycoerythrin from the macroalgaCorallina officinalis (Rhodophyceae) and application of a derived phycofluor probe for detecting sugar-binding sites on cell membranes (1991)
    Springer
    Journal of applied phycology 3 (1991), S. 345-354

    Notes: Abstract R-Phycoerythrin (absorption spectrum 280; 495;sh 535, 564 nm with A564/A280 ratio of 5.3) was purified from the red macroalgaCorallina officinalis. The relative molecular mass determined from PAGE was 240 000. SDS-PAGE demonstrated two major subunits ofM r 20 000 and 21 000, respectively, and a minor subunit ofM r 30 000. A fucospyranosyl phenylisothiocyanate conjugate was prepared and this novel fluorescent affinity reagent used in conjunction with a flow cytometer to probe fucose-binding sites on blood mononuclear cells. By varying the sugar and using other phycobiliproteins the approach has the potential for simultaneously monitoring different sugar binding sites on subsets of cells within populations.
