A novel halogenated compound possessing antibiotic and cytotoxic activities isolated from the fungus Resinicium pinicola (J. Erikss.) Erikss. & Hjortst.

Pinicoloform, a novel unbranched acyclic compound containing a trichloromethyl group, has been isolated from extracts of the mycelia of the Basidiomycete Resinicium pinicola. It was isolated because of its ability to induce morphological and physiological differentiation of mammalian cells, although it also exhibits antibiotic and cytotoxic activities. The structure of pinicoloform was determin...

Analysis of the Geotropic Orientation of Young Rats. Ix by W. J. Crozier and G. Pincus

With lines of rats well inbred it has been shown 1 that the relationship between orientation angle 0 and slope of surface a in the geotropic creeping of young rats is specific and quantitatively reproducible. I t is also found that the capacity of individuals to exhibit variation in geotropic response (orientation) is likewise a reproducible function of the genetic constitution of these rats. T...

Ascospore development in Ceratocystis sensu lato (Fungi): a review

Ceratocystis. Ceratocxstiopsis and Ophiostoma are important pathogens of trees and some agricultural crops and have recently been found on proteas and forest trees in South Africa. Taxonomic controversy exists regarding these genera and ultrastructural studies on the development of asci, uniquely shaped ascospores and centrum structure are inadequate. This rev iew summarises current knowledge o...

Structural characterization of lignin during Pinus taeda wood treatment with Ceriporiopsis subvermispora.

Pinus taeda wood chips were biotreated with Ceriporiopsis subvermispora under solid-state fermentation for periods varying from 15 to 90 days. Milled wood lignins extracted from sound and biotreated wood samples were characterized by wet-chemical and spectroscopic techniques. Treatment of the lignins by derivatization followed by reductive cleavage (DFRC) made it possible to detect DFRC monomer...
