Importância das culturas de cobertura no aumento do grau de micorrização de tom...

Os microrganismos benéficos ocorrem naturalmente em ecossistemas pouco intervencionados, mas muitas práticas associadas à agricultura intensiva resultam em desequilíbrios de biodiversidade que os desfavorecem relativamente a outras espécies não-benéficas. Nestes sistemas intensivos, a ocupação do solo no período de outono-inverno com culturas de cobertura à base de leguminosas, gramíneas, ou misturas biodiversa...

Metalaxyl Degradation by Mucorales Strains Gongronella sp. and Rhizopus oryzae

In this study, the degradation of metalaxyl was investigated in the presence of two Mucorales strains, previously isolated from soil subjected to repeated treatments with this fungicide and selected after enrichment technique. Fungal strains were characterised by a polyphasic approach using phylogenetic analysis of the Internal Transcribed Spacer (ITS) gene region, phenotypic characterisation by Matrix-Assisted...

Degradation of the fungicide metalaxyl by Mucorales strains

Degradation of Metalaxyl and Folpet by Filamentous Fungi Isolated From Portugue...

Degradation of xenobiotics by microbial populations is a potential method to enhance the effectiveness of ex situ or in situ bioremediation. The propose of this study was to evaluate the impact of repeated metalaxyl and folpet treatments on soil microbial communities and to select soil fungal strains able to degrade these fungicides. Results showed an enhanced degradation of metalaxyl and folpet in vineyards so...

Characterisation by molecular biology and MALDI-TOF ICMS of zygomycete Gongrone...

Zygomycete Gongronella sp. CCMI 1101 (MUM 10.263) was isolated from an Alentejo vineyard soil submitted to repeated treatments with the fungicide metalaxyl. This fungicide is widely used against Oomycetes species that causing downy mildew. After selective enrichment, adapted Gongronella sp. CCMI 1100 (MUM 10.262) showed high tolerance to metalaxyl with EC50 of 36.1 mg L-1. Additionally, this adapted fungus was ...

Optimization of application procedure for fixation of monocationic salt onto co...

A novel application procedure for imparting antibacterial properties onto cotton is described. The modified cotton was obtained by polymerization of glycidyl methacrylate (GMA) with 1,4 diazabicyclo[2,2,2]octane monocationic salt (MS) derivative in the presence of the free radical initiators sodium bisulfite and potassium persulfate. Out of the four application protocols tested, use of an exhaustion procedure t...
