This is a continuous study on a decolorization strain, Pseudomonas luteola, which involves treating seven azo dyes with different structures. This study focuses mainly on determining both the mechanism of decolorization by P. luteola and the activity of azoreductase from P. luteola as well as identifying and assessing the toxicity of metabolic products of azo dyes. The growth of P. luteola reached the stationary phase after shaking incubation for 24 hours. Then, while being kept static, the color of seven tested azo dyes (100 mg/l) could be removed. The proportion of color removal was between 59–99%, which figure is related to the structure of the dye. Monoazo dyes (RP2B, V2RP and Red 22) showed the fastest rate of decolorization, i.e. from 0.23–0.44 mg dye-mg cell–1 hr–1. P. luteola could remove the color of V2RP and a leather dye at a concentration of 200 mg/l, and as to the rest of the azo dyes, it could remove at a concentration of up to 100 mg/l. Decolorization of RP2B and Red 22 required activation energy of 7.00 J/mol and 6.63 J/mole, respectively, indicating that it was easier for azoreductase to decolorize structurally simple dyes. The kinetics of azoreductase towards seven azo dyes suggested a competitive inhibition model be applied. Microtox® was used to analyze the toxicity of the metabolic products of azo dyes. EC50 showed differences in toxicity before and after the azo dyes had been metabolized. Analysis revealed significant differences between the results obtained by EC50 with Blue 15 and those obtained with the leather dye, indicating that the toxicities of the metabolic products were increased. The differences obtained by EC50 with Red 22, RP2P and V2RP were small, and Black 22 showed no such difference. Sulfanic acid and orthanilic acid may be the intermediate products of Violet 9 and RP2B, respectively. However, according to FT-IR analysis, aromatic amines were present in the metabolic product.

O estudo realizou a análise bacteriológica de sabões líquidos utilizados para lavagem das mãos dos profissionais de saúde. Trata-se de estudo exploratório transversal, desenvolvido nas unidades de internação de hospital de médio porte em Fortaleza/CE. Os dados foram colhidos no período de maio a julho de 2007. Do total de 59 frascos com sabão líquido, 33 continham os seguintes microorganismos: Burkholderia cepacia (n=14), Pseudomonas putidas (9), Pseudomonas aeruginosa (3), Klebsiella pneumoniae (3), Enterobacter cloacae (2), Pseudomonas luteola (2). As unidades com maior número de amostras contaminadas foram a clínica cirúrgica (n=7) e a clínica dermatológica (n=4). A contaminação também foi verificada em frasco original do mesmo lote de sabão líquido usado para abastecer as saboneteiras. Podemos concluir ser necessário disciplinar e controlar a qualidade desses produtos nas linhas de produção tanto quanto nas fases de uso nos serviços de saúde, sobretudo porque sua utilidade se presta à prevenção de infecção hospitalar.
