This study was conducted to improve the pentachlorophenol (PCP) bioremediation ability of white-rot fungi in highly contaminated field soils by manipulating bioaugmentation variables. These were the dry weight percentage of fungal inoculum addition (31-175 g kg(-1)), PCP concentration (100-2137 mg kg(-1) PCP), fungal inoculum formulation, and time (1-7 wk). Five fungal isolates were used: the N...

In a Perspective, Julie Garon and Walter Orenstein discuss Lessler and colleagues' modeling study on measles vaccination and the implications for triggered and routine immunization programs.

During two consecutive years, studies on the sand fly fauna in Poço das Antas and Fazenda Bom Retiro, two Atlantic Rain Forest Reserves from the State of Rio de Janeiro, were performed using Shannon traps, CDC light traps and human bait collections. Eleven species were identified; Lutzomyia longipalpis, L. migonei, L. edwardsi, L. intermedia, L. whitmani, L. fischeri, L. shannoni, L. ayrozai, L...

The article provides an overview of information on the two invasive species of Siberia that are weeds of crops Malva verticillata L. and Vicia hirsuta (L.) S.F. Gray. It provides information on the distribution of species, morphology, biological and ecological characteristics. Active ability of Vicia hirsuta to spread with the seed of oil plants and honey plants was revealed. The possible conse...

Separation of Trametes versicolor laccase from a commercial preparation was carried out using Three-Phase-Partitioning (TPP) technique. The conditions were optimized and the most favorable ammonium sulphate concentration (70% w/v), crude to t-butanol ratio (1.0:2.0) and pH (4.5) resulted in 56.22% yield with 1.65-fold purity of laccase. For further improvement in purification, an improved versi...

Two species Luzonomyza gaimarii sp. nov. and Luzonomyza hirsuta sp. nov. are described as new to science. A key to separate species of the genus is provided.

The identity of the fungi associated with and responsible for wood decay could lead to the development of more environmentally benign wood preservative systems. In this study we have reconstructed the phylogenetic tree of a select group of basidiomycete fungi using nucleotide sequences of the internal transcribed spacer (ITS) region. We then compared this to trees generated from restriction fra...
