Effect of Tolypothrix tenuis and Microchaete tenera on biochemical soil properties and maize growth
Exopolysaccharide (EPS) and biomass from strains Tolypothrix tenuis and Microchaete tenera were added to the soil and the activity of β-glucosidase, urease, protease, phosphomonosterase, arylsulphatase, and dehydrogenase were determined. Both treatments induced a promotion of microorganisms growth,...

Exopolysaccharide (EPS) and biomass from strains Tolypothrix tenuis and Microchaete tenera were added to the soil and the activity of β-glucosidase, urease, protease, phosphomonosterase, arylsulphatase, and dehydrogenase were determined. Both treatments induced a promotion of microorganisms growth, indicated by a constant increase of dehydrogenase activity. Protease and dehydrogenase activity increased with time up to day 400. β-gluosidase, urease, and phosphomonoesterase activity changed from a maximal increase at day 90 to lower values at day 400. Aryl-sulphatase activity decreased with T. tenuis and increased with M. tenera biomasses, after 400 days.
