1. Evaluation of hematite and quartz flotation kinetics using surfactant produced by Rhodococcus erythropolis as bioreagent
Abstract The use of biosurfactants as reagents represents a promising alternative to the conventional surfactants used in the mineral industry because they may present low toxicity and high biodegradability. Therefore, this research studied the hematite and quartz flotation kinetics using surfactant produced by Rhodococcus erythropolis as bioreagent. The flo

2. Bioflotation of apatite and quartz: Particle size effect on the rate constant
This work deals with the fundamental aspects of apatite and quartz bioflotation using R. opacus bacteria as a bioreagent. It was observed that the flotability of both minerals depends on the pH value and the mineral particle size. The maximum flotability of both minerals was presented at a pH value of 5, achieving values of 90% and 14% for apatite and quartz

3. FUNDAMENTAL ASPECTS OF THE ADHESION OF RHODOCOCCUS OPACUS STRAIN ONTO APATITE SURFACE / ASPECTOS FUNDAMENTAIS DA ADESÃO DA ESTIRPE RHODOCOCCUS OPACUS NA SUPERFÍCIE DE APATITA
A bactéria Rhodococcus opacus apresenta a capacidade de tornar hidrofóbica a superfície do mineral de apatita, devido aos compostos presentes na sua parede celular. Para avaliar esta característica da bactéria, foi estudada no presente trabalho a influencia de diferentes parâmetros para tentar entender a interação entre bactéria e o mineral. Os resu

4. BIOFLOTAÇÃO DE MAGNESITA, CALCITA E BARITA USANDO RHODOCOCCUS OPACUS COMO BIORREAGENTE / BIOFLOTATION OF MAGNESITE, CALCITE AND BARITE USING RHODOCOCCUS OPACUS AS BIOREAGENT
A bactéria Rhodococcus opacus foi avaliada como biorreagente para a flotação dos minerais da magnesita calcita e barita. As análises para determinar a conformação de parede o R. opacus estabelecem que é constituída por macromoléculas com características anfipáticas. O balanço entre grupos catiônicos e aniônicos da parede atribui um ponto isoel�

5. Cloning and Characterization of a Gene Cluster Involved in Cyclopentanol Metabolism in Comamonas sp. Strain NCIMB 9872 and Biotransformations Effected by Escherichia coli-Expressed Cyclopentanone 1,2-Monooxygenase†
Cyclopentanone 1,2-monooxygenase, a flavoprotein produced by Pseudomonas sp. strain NCIMB 9872 upon induction by cyclopentanol or cyclopentanone (M. Griffin and P. W. Trudgill, Biochem. J. 129:595-603, 1972), has been utilized as a biocatalyst in Baeyer-Villiger oxidations. To further explore this biocatalytic potential and to discover new genes, we have clo
