Physiological Characterization of Fungal Inoculum for Biotechnological Remediation of Soils
Provedor de dados: 52
Autores: Ballaminut,Nara; Machado,Kátia Maria Gomes; Oliveira,Luisa Helena dos Santos; Matheus,Dácio Roberto.
The aim of this work was to study the bioremediating potential of Lentinus crinitus CCIBt2611 according to the physiological condition of the inoculum. Inoculum was prepared using sugarcane ground husk (C:N 90), at several physiological ages and applied in soil contaminated with pentachlorophenol. The inoculum's potential was assessed by evaluating the mycelium's vigor at soil's colonization, determination of peroxidase and phenoloxidase activities, in vitro degradation of Remazol Brilliant Blue R and in vivo degradation of pentachlorophenol. The results showed that the assessed parameters were relevant to identify the quality of the inoculum. For L. crinitus, 10 day old inoculum showed good soil-colonization speed with significant enzymatic activities,...

Screening mitosporic fungi for organochlorides degradation
Provedor de dados: 58
Autores: Vitali,Vera Maria Valle; Machado,Kátia Maria Gomes; Andrea,Mara Mercedes de; Bononi,Vera Lúcia Ramos.
Fifty-five isolates of filamentous fungi were studied regarding their ability to decolorize Remazol brilliant blue R dye. The fungi were isolated from soil in the Baixada Santista region, which is contaminated with industrial residues containing a mixture of organochlorine compounds, mainly hexachlorobenzene. The fungi were grown in liquid malt extract medium with 0.02% of dye and shaken at 200 rpm for 14 days at 28 ± 2ºC. Two types of behavior regarding the dye were observed: adsorption and degradation. Eupenicillium baarnenseSsp1951 and Ssp1952 and Eupenicilliumcrustaceum SSP1953 presented high RBBR decolorization and were then analyzed regarding their ability to degrade 14C-hexachlobenzene (4138.31 mg HCB per kg soil) during a 56 days culture at 28 ±...
