This study presents a 7-year retrospective analysis of seasonal variations in the prevalence of Cryptococcus neoformans var. grubii and Cryptococcus gattii in decayed wood inside trunk hollows of 518 trees belonging to 20 species in north-western India during 2000-2007. Of the 1,439 wood samples investigated, 406 (28.2%) were found to be positive for the Cryptococcus neoformans species complex ...

Pulp & Paper Canada T 116 106:5 (2005) ❘ ❘ ❘ 41 HE ADVERSE EFFECTS of wood decay on chip quality, pulp yield, and pulp quality have been well documented [8,2024,27]. Decay can enter the chip supply either by utilization of decayed standing wood [14] or through prolonged or improper storage [16]. The net effect of using decayed wood for pulping is cost increases due to decreases in pulp yield, r...

The production of the H(2)O(2)-generating enzyme pyranose oxidase (POD) (EC 1.1.3.10) (synonym, glucose 2-oxidase), two ligninolytic peroxidases, and laccase in wood decayed by three white rot fungi was investigated by correlated biochemical, immunological, and transmission electron microscopic techniques. Enzyme activities were assayed in extracts from decayed birch wood blocks obtained by a n...

Sweetgum (Liquidambar styraciflua L.) wood blocks were decayed by Postia (= Poria) placenta in soilblock cultures. Decay was terminated at various weight losses, and the pore volumes available to four low molecular weight molecules, (water, 4 Å,; glucose, 8 Å,; maltose, 10 Å; and raffinose, 128,) and three dextrans (Mr 6,000, 38 Å; 11,200, 51 Å; and 17,500, 61 Å) were determined by the solute e...

Wood decayed and colored by fungi, colloquially known as ‘spalted wood’, has been a source of art folklore across numerous cultures. From intarsia marquetry in Italy Germany to woodturning the U.S. carving mythology Chile, uses of, stories about, spalted wood are explored, well how those have shaped their surrounding cultures modern science.

A new Neotropical species of the genus Stenochironomus Kieffer, 1919 is described and illustrated based on adult male, pupa and larva. The larvae were reared from decayed wood collected in black-water Amazonian streams.
