To study the antimicrobial activity of fungi isolated from Brazilian cerrado soil. Material and methods. A total of 200 fungal strains were isolated from soil samples collected from Serra do Cipó National Park in Brazil. Antibacterial activity against Escherichia coli, Staphylococcus aureus, Salmonella typhimuriu, Streptococcus pyogenes andListeria monocytogenes was screened. Results. Around 67% of the extracts showed activity against at least one of the tested bacteria. Thirteen isolates, selected as the most common species found in the studied soil samples (over 50% of all isolates), were microscopically identified as Chaetomium cupreum, Curvularia senegalensis, Fusarium oxysporum, Penicillium citrinum, Penicillium janthinellum, Penicillium paxilli, Penicillium sclerotiorum, Penicillium simplicissimum, Penicillium waks-manii, Rhizopus stolonifer, Syncephalastrum r acemosum, Trichoderma koningii and Trichoderma reesei. Large scale experiment proved positive antibacterial results for Penicillium sclerotiorum and Penicillium simplicissimum, since bioactive metabolites (sclerotiorin, isochromophilone VI, pencolide and penicillic acid) were recovered from their fermentation in preparative scale. Conclusion. Cerrado soil fungi constitute another important source of antibiotics producing micro-organisms that can be further exploited a s source of lead compounds for anti-infective agents industry.

This work applies pedometric tools to analyse soil property information relevant to morphological characterisation and soil classification. The objective of this paper was further to identify similarities in soil properties among a soil profile collection. The harmonisation of soil data enables the comparison between soil profiles, transference of information and modelling of soil horizons distribution. The statistical procedures were implemented in R software, through the Algorithms for Quantitative Pedology (AQP package), which contains a collection of algorithms to model soil resources and aid soil classification, soil profile aggregation and visualisation. The procedures allowed definition of values for soil properties in every one-centimetre layer of the soil profile, by regrouping the data in a different layer thickness, and it was possible to analyse similarity between profiles using a dissimilarity matrix for each depth slice. The AQP allowed analysis of a large number of soil profiles, in terms of vertical variability of soil continuous properties (e.g. sand and clay content, and pH) and for categorical variables, such as diagnostic horizons. Soil depth functions were developed to represent soil properties and probability of occurrence to diagnostic horizons to a large data set, and the dissimilarity analysis allowed separation of a small group of similar soil profiles and further qualitative comparison among the select profiles. |
