Cold-adapted strains as plant growth-promoting bacteria on soybean seeds and biocontrol agents against Macrophomina phaseolina.

Aim: The aim was to characterize cold-adapted bacteria by testing their PGP features and antagonistic activity against Macrophomina phaseolina, both in vitro and coating soybean seeds (Glycine max [L.] Merr.).

Exploring Agaricomycetes from the Paranaense rainforest (Misiones, Argentina) as an unconventional source of fibrinolytic enzymes.

Fungal fibrinolytic enzymes, secreted by some Agaricomycetes, are recognized as important thrombolytic agents due to their ability to rapidly dissolve thromboembolic clots. The present work evaluated fibrinolytic and proteolytic secretion abilities of 35 Agaricomycetes isolates from the Paranaense rainforest (Misiones, Argentina). We detected proteolytic activity in 40% of the strains while nine strains showed fibrinolytic activity.

Effect of chemical and metallic compounds on biomass, mRNA levels and laccase activity of Phlebia brevispora BAFC 633.

Nine aromatic compounds (caffeic acid, syringaldehyde, vanillic acid, guaiacol, vanillin, sinapic acid, syringol, syringic acid and ferulic acid) and four metallic compounds (CuSO4, AgNO3, MnSO4, and CaCl2) were tested for their ability to increase laccase (Lac) activity in the ligninolytic basidiomycete Phlebia brevispora BAFC 633. The addition of syringaldehyde, syringol, guaiacol, sinapic acid, vanillin, ferulic acid and CuSO4 showed a positive effect on fungal growth; however, it decreased dramatically with the addition of AgNO3 and did not undergo changes in the presence of CaCl2 or MnSO4. Lac activity increased with the addition of all the compounds tested, depending on the concentration and the day of culture.
