Penicillium simplicissimum solubilized up to 80% of the titanium in granitic rocks but less than 2% of the titanium in basaltic rocks.

A new antifungal antibiotic xanthoepocin was isolated from the culture broth of Penicillium simplicissimum IFO5762. Xanthoepocin was obtained from the culture fluid by solvent extraction and chromatographic purification. It showed antibiotic activity against Gram-positive bacteria and yeasts.

When Penicillium simplicissimum is grown on veratryl alcohol, anisyl alcohol, or 4-(methoxymethyl)phenol, an intracellular covalent flavin-containing vanillyl-alcohol oxidase is induced. The induction is highest (up to 5% of total protein) during the growth phase. In addition to vanillyl-alcohol oxidase, an intracellular catalase-peroxidase is induced. Induction of vanillyl-alcohol oxidase in P...

Four new okaramine congeners, okaramines J, K, L and M, were isolated from okara fermented with Penicillium simplicissimum ATCC 90288, together with five biogenetically related compounds, cyclo (8a-(α,α-dimethylallyl)-L-Trp-8a-(α,α-dimethylallyl)-L-Trp), cyclo (N (8)-(α,α-dimethylallyl)-L-Trp-6a'-(α,α-dimethylallyl)-L-Trp), cyclo (L-Trp-L-Trp), cyclo (6a'-(α,α-dimethylallyl)-L-Trp-L-Trp), and c...

The objective of this study was to investigate the capacity of decolorization and detoxification of the textile dyes Reactive Red 198 (RR198), Reactive Blue 214 (RB214), Reactive Blue 21 (RB21) and the mixture of the three dyes (MXD) by Penicillium simplicissimum INCQS 40211. The dye RB21, a phthalocyanine, was totally decolorized in 2 days, and the others, the monoazo RR198, the diazo RB214 an...

In this research, Zn, Ni, and Cu recovery from mobile phone printed circuit boards was investigated. The initial pH pulp density using Aspergillus niger or Penicillium simplicissimum fungi were optimized to improve the of a central composite design. Fungi able recover 97% Cu. Often for Ni recovery, A. more effective, but in low densities pH, P. preferred. For is appropriate at lower than 6, out...

Vanillyl-alcohol oxidase catalyses the oxidation of several 4-hydroxybenzyl alcohols by using 8-alpha-(N3-histidyl)-FAD as a covalently bound prosthetic group. Crystals of vanillyl-alcohol oxidase from Penicillium simplicissimum have been grown by using the vapor diffusion technique. The space group was found to be I, with cell dimensions a = b = 140.5 A, c = 132.9 A. Diffraction data have been...
