PMID: 18553484
Biotechnol Bioeng. 1984 Aug;26(8):970-2. doi: 10.1002/bit.260260822.

To convert sugar mixtures containing cellobiose, glucose, and xylose to ethanol in a single step, the possibility of using a coculture consisting of Clostridium saccharolyticum and Zymomonas anaerobia was studied. In monoculture, C. saccharolyticum utilized all three sugars; however,...

Toward a control of lignin and manganese peroxidases hypersecretion by Phanerochaete chrysosporium in agitated vessels: Evidence of the superiority of pneumatic bioreactors on mechanically agitated bioreactors.

Biotechnology and bioengineering

PMID: 18609572
Biotechnol Bioeng. 1993 Feb 20;41(4):440-50. doi: 10.1002/bit.260410407.

Phanerochaete chrysosporium and cultivated both mechanically agitated and pneumatic bioreactors. In the pneumatic devices, the yields of lignin and manganese peroxidases as well as extracellular protein, were considerably increased as compared with mechanically agitated bioreactors. Lignin peroxidase and manganese...

Novel manifestation of alpha-clustering structures: new "alpha+208Pb" states in 212Po revealed by their enhanced E1 decays.

Physical review letters

Phys Rev Lett. 2010 Jan 29;104(4):042701. doi: 10.1103/PhysRevLett.104.042701. Epub 2010 Jan 25.

Excited states in 212Po were populated by alpha transfer using the 208Pb(18O,14C) reaction, and their deexcitation gamma rays were studied with the Euroball array. Several levels were found to decay by a unique E1 transition (Egamma

Immobilization of fungal spores by adhesion.

PMID: 24420585
Photosynth Res. 1990 Dec;26(3):203-12. doi: 10.1007/BF00033133.

The mechanism of excitation energy distribution between the two photosystems (state transitions) is studied in Synechocystis 6714 wild type and in wild type and a mutant lacking phycocyanin of Synechocystis 6803. (i) Measurements of fluorescence transients and spectra demonstrate...

Recombinant Ad35 adenoviral proteins as potent modulators of human T cell activation.
