This work describes the cytopathic effect on cells, cytotoxic action on mice, and antiviral activity of cinnabarin. This substance had no effect on mouse neuroblastoma cells (NA cell, ATCC clone C-1300) at a concentration of 0.31 mg/ml, it was not able to cause toxic effects in mice at concentrations of 1000 mg/kg, and reduced by four times the titers of the rabies virus at concentrations of 0.31 mg/ml.

Among three strains of Pycnoporus sanguineus, MIP 89007 produced more cinnabarin than MIP 95001 and MIP 95002. The antimicrobial activity of cinnabarin was tested against 11 species of bacteria isolated from food. Bacillus cereus and Leuconostoc plantarum were the most sensitive to cinnabarin, being inhibited by 0.0625 mg/ml. Klebsiella pneumoniae was the least sensitive (>4.0 mg/ml).

Based on intensive search of literature records of xylophilous basidiomycetes in mangroves, a list with 112 species is presented. These species are distributed in 63 genera, 27 families and 9 orders. Polyporaceae is the most represented family with 33 species; Phellinus is the genus with the highest number of species (7). Brazilian mangroves, with 55 species, are the best known areas. The most frequent host is Rhizophora mangle with 34 species recorded on it. For each species the localities and substrates are provided, when these data were available in the respective original article.

Biopulping of Eucalyptus grandis wood chips with Phanerochaete chrysosporium RP-78 was evaluated under non-aseptic conditions in laboratory and mill wood-yard. The ability of P. chrysosporium to compete with indigenous fungi present in fresh wood chips was notorious under controlled laboratory experiments. A subsequent step involved an industrial test performed with 10-ton of fresh wood chips inoculated and maintained at 37"38C for 39 days in a biopulping pilot plant. Biotreated wood chips were pulped in a chemithermomechanical pulping mill. Net energy consumption during refining was 745 kWh ton -1 and 610 kWh ton -1 of processed pulp for control and biotreated wood chips, respectively. Accordingly, 18.5% net energy saving could be achieved. Biopulps contained lower shive content and had improved strength properties compared to control pulps. Tensile index improved from 25"1 N m g -1 to 33.6"0.5 N m g -1 and delamination strength from 217"19 kPa to 295"30 kPa.

Fuscoporia bifurcata is described from southern Brazil based on collections from mangrove areas on Santa Catarina Island, in the state of Santa Catarina. The new species is characterized by hymenial setae with a bifurcate or spiny apex. A description with illustrations, an updated key to species of Fuscoporia from southern Brazil and a key to species of Hymenochaetaceae reported from mangroves are provided.
