Short communication: Changes in soil enzyme activities following additions of cyanobacterial biomass and exopolysaccharide
The aim of this research was to establish changes in the overall activity of extracellular enzymes: β-glucosidase, phosphomonoesterase, arylsulphatase, protease and urease and the intracellular enzyme dehydrogenase produced by the addition of Tolypothrix tenuis and Microchaete tenera (Cyanobacteria)...

Both biomass and EPS of M. tenera significantly (p < 0.05) increased β-glucosidase activity by 0.1 and 29.3%, respectively. Both cyanobacteria species significantly (p < 0.05) increased urease activity by 15 ± 1%. Cyanobacterial biomass and EPS from T. tenuis and M. tenera produced significant increases in protease (76-90%, 101-136%), phosphomonoesterase (19-27%, 13-22%), arylsulphatase (148-167%, 406-174%) and dehydrogenase activity (16-32%, 43-30%). © 2000 Elsevier Science Ltd. 2000 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00380717_v32_n13_p1985_DeCaire http://hdl.handle.net/20.500.12110/paper_00380717_v32_n13_p1985_DeCaire |
