The fate of 14C-pentachlorophenol (14C-PCP) in soil inoculated with each of four wood degrading fungi was studied. After 9 wk of incubation with the fungi, the majority of the 14C (between 34 and 65%) was found bound to humic (HA), fulvic acid (FA) and humin, with lesser amounts found in the organic-extractable fraction or mineralized. The highest amounts of PCP were bound to HA (20-36% , compa...

Chaetochromones A (1) and B (2), two novel polyketides, were isolated from the crude extract of fungus Chaetomium indicum (CBS.860.68) together with three known analogues PI-3(3), PI-4 (4) and SB236050 (5). The structures of these compounds were determined by HRESI-MS and NMR experiments. Chaetochromones A (1) and B (2) are a member of the polyketides family, which might originate from a simila...

We previously found that endo-beta-xylosidase from Patinopecten is an endo-type glycosidase that cleaves the xylosyl serine linkage between a glycosaminoglycan chain and its core protein (Takagaki, K., Kon, A., Kawasaki, H., Nakamura, T., Tamura, S., and Endo, M. (1990) J. Biol. Chem. 265, 854-860). Screening for endo-beta-xylosidase activity in several cellulases detected this activity in the ...
