Characterization of aapP and nopP genes related to the biological nitrogen fixation efficiency with soybean in contrasting strains of Bradyrhizobium japonicum

Soybean (Glycine max) is considered one of the most economically important agricultural crops in Brazil. Due to the high protein content of its grains, this crop demands a greater amount of nitrogen (N) for production. In general, for soybean, nitrogen fertilization costs through chemical fertilizers are considered high. However, the biological nitrogen fixation (BN.. Read More»

    S.H. Umeo, G.P.N. Souza, P.M. Rapachi, D.M. Garcia, L.D. Paccola-Meirelles, J.S. Valle, N.B. Colauto and G.A. Linde

Submerged cultivation of medicinal basidiomycetes is a reproducible and efficient method of producing mycelia and metabolites. The antioxidant activity indicates its medicinal properties and is an important tool for basidiomycete screening. In this study, we analyzed the production of mycelial biomass and exopolysaccharides and the antioxidant activity of basidiomycete strains in submerged cult.. Read More»

Antifungal and antibacterial activities of Petroselinum crispum essential oil

    G.A. Linde, Z.C. Gazim, B.K. Cardoso, L.F. Jorge, V. Tešević, J. Glamoćlija, M. Soković and N.B. Colauto

Parsley [Petroselinum crispum (Mill.) Fuss] is regarded as an aromatic, culinary, and medicinal plant and is used in the cosmetic, food, and pharmaceutical industries. However, few studies with conflicting results have been conducted on the antimicrobial activity of parsley essential oil. In addition, there have been no reports of essential oil obtained from parsley aerial parts, except seeds, .. Read More»

Lentinus crinitus strains respond differently to cultivation pH and temperature

Fungus ability to respond to environmental changes allows their adaptation to a wide variety of conditions such as pH, temperature, light, nutrient availability, chemicals, and competition among species. Temperature and pH can affect fungal growth as well as their metabolism. Knowing these factors on fungus species is relevant for the development of biotechnological.. Read More»

Characterization of the inaA gene and expression of ice nucleation phenotype in Pantoea ananatis isolates from Maize White Spot disease

    A.M. Miller1, J.E.F. Figueiredo3, G.A. Linde4, N.B. Colauto4and L.D. Paccola-Meirelles1,2,4

Maize White Spot (MWS), a foliar disease caused by Pantoea ananatis, could cause up to 60% yield loss. Some strains of P. ananatis harboring the ice nucleation gene inaA catalyze the formation of ice nuclei, causing tissue damage at temperatures slightly below freezing. Little is known about the relationship between the presence of the ina gene in this maize pathogen and its expression during t.. Read More»

Effect of different compounds on the induction of laccase production by Agaricus blazei

    J.S. Valle, L.P.S. Vandenberghe,A.C.C. Oliveira, M.F. Tavares,G.A. Linde, N.B. Colauto, C.R. Soccol

Laccases are polyphenol oxidases produced by many fungi and have many applications in textile, food and beverage, and pulp and paper industries. Laccase production can be induced using aromatic or phenolic compounds that mostly affect the transcription of laccase-encoding genes. In this study, we analyzed laccase and biomass production by Agaricus blazei in the pres.. Read More»

Identification and characterization of genes related to cellulolytic activity in basidiomycetes

    A.F.N. Volpini, T. Thomazine, S.H. Umeo, G.A. Pereira, G.A. Linde, J.S. Valle, N.B. Colauto, F.G. Barcellos and S.G.H. Souza

Enzymes produced by basidiomycetes that are involved in the cellulose degradation process, and their respective codifying genes, must be identified to facilitate the development of novel biotechnological strategies and applications in the agro-industry. The objective of this study was to identify prospective cellulase-producing genes and characterize their cellulolytic activity, in order to elu.. Read More»

Iron translocation in Pleurotus ostreatus basidiocarps: production, bioavailability, and antioxidant activity

    M.E. Yokota1, P.S. Frison1, R.C. Marcante1, L.F. Jorge1, J.S. Valle1, D.C. Dragunski2, N.B. Colauto1 and G.A. Linde10

Translocation of minerals from substrate to mushrooms can change the medicinal characteristics, commercial value, and biological efficiency of mushroom. In the present study, we demonstrated that addition of iron to the substrate reduces the yield of Pleurotus ostreatus mushroom. The biological efficiency of the mushroom varied from 36.53% on the unsupplemented substrate to 2.08% for the substr.. Read More»

Use of sugarcane molasses by Pycnoporus sanguineus for the production of laccase for dye decolorization

    R.A. Marim, A.C.C. Oliveira, R.S. Marquezoni, J.P.R. Servantes,B.K. Cardoso, G.A. Linde, N.B. Colauto and J.S. Valle

Pycnoporus sanguineus is a white-rot basidiomycete that produces laccase as the only oxidoreductase; enzyme synthesis depends on cultivation variables, and fungal species and strain. Laccases have wide substrate specificity, oxidize a broad range of compounds, and show potential for use in dye decolorization. We evaluated laccase production in a recently isolated st.. Read More»

Genomic variability of Pantoea ananatis in maize white spot lesions assessed by AFLP markers

    A.M. Miller, J.E.F. Figueiredo, C.L. Chaves, E.A. Ruas, M.I. Balbi-Peña, N.B. Colauto and L.D. Paccola-Meirelles

Measures to control maize white spot (MWS) caused by Pantoea ananatis are preferentially based on resistant cultivars. A lack of knowledge on the genetic variability of pathogens could interfere with the development and utilization of controlling strategies in this pathosystem. The main goals of this study were to investigate the genetic variability of 90 P. ananati.. Read More»
