OBJECTIVES To evaluate BD MGITTM TBc® technique for identifying the Mycobacterium tuberculosis complex using isolates obtained in liquid and solid media. METHODS A descriptive study was conducted in which 117 isolates were analyzed by the immune-chromatography technique obtained from solid and liquid cultures to identify the Mycobacterium tuberculosis complex. The kappa coefficient was calcul...

Various basidiomycetes and deuteromycetes, grown in liquid and solid culture media, were compared for their laccase-producing ability and for the inducing effect of soil and agricultural residues on laccase production. Laccase activity in extracts of all solid media was higher than that of the liquid media. In liquid cultures, fungal laccase activity in extracts of pea (Pisum sativum) straw-tre...

The objective of this study was to optimize continuous acetone-butanol-ethanol (ABE) fermentation using a two stage chemostat system integrated with liquid-liquid extraction of solvents produced in the first stage. This minimized end product inhibition by butanol and subsequently enhanced glucose utilization and solvent production in continuous cultures of Clostridium acetobutylicum B 5313. Dur...
