Lignin is nature’s largest source of phenolic compounds. Its recalcitrance to enzymatic conversion still a limiting step increase the value lignin. Although bacteria are able degrade lignin in nature, most studies have focused on degradation by fungi. To understand which use as sole carbon source, natural selection over time was used obtain enriched microbial consortia 12-week period. The microorganisms establish these were commercial and backyard compost soils. Cultivation occurred at two...
Biological nitrogen fixation (BNF) represents the main input source of N in tropical savannas. BNF could be particularly important for Brazilian savannas (known as Cerrado) that show a highly conservative cycle. We evaluated effects seasonal precipitation and nutrient additions on nifH gene abundance soils from long-term fertilization experiment Cerrado's native area. The consists five treatments: (1) control, (2) liming, (3) (N), (4) + phosphorus (NP), (5) (P) additions. sequence was...
Eusocial animals, such as the termites, often build a nest-like structure called mound that provides shelter with stable internal conditions and protection against predators. Termites are important components of Brazilian Cerrado biota. This study aimed to investigate bacterial community composition diversity Syntermes wheeleri termite-mound soil using culture-independent approaches. We considered vertical profile by comparing two different depths (mound surface 60 cm) seasonality samplings...
The occurrence of toxic blooms cyanobacteria has been a matter public health interest due to the cyanotoxins produced by these microorganisms. Cylindrospermopsin (CYN) is cyanotoxin particular concern its effects on humans. This study investigated removal and CYN in ripened slow sand filters (SSFs) treating water from Paranoá Lake, Brasilia, Brazil. Four pilot-scale SSFs were operated for 74 days. Two contamination peaks with applied along filtration run. improvement any evaluated quality...
