SSI Enzyme Activity Assay. Method in a nutshell. (to microplate reader). Fluorescence. Substrate capable of fluorescence. When enzyme binds substrate we have fluorescence. Enz y me (of course!!). Mix soil and buffer in a blender Transfer soil solution to a 96-well plate

Method in a nutshell (to microplate reader) Fluorescence Substrate capable of fluorescence When enzyme binds substrate we have fluorescence Enzyme (of course!!)
Mix soil and buffer in a blender • Transfer soil solution to a 96-well plate • Add substrates into the wells • Incubate at 25oC for 80 min • Centrifuge the plate to seperate soil and supernatant • Transfer the supernatant to another plate • Read fluorescence in a plate reader S2 S3 S4 S5 S6 S7 S8 S1 B-glucosidase substrate N-acetyl-glucosaminidase substrate Phosphatase substrate Cellulosebreakdown Chitinbreakdown Phosphatebreakdown Makeyourguess…
B-glucosidase activity higher in SGS litter quality …. Pulse? N-acetylglucosaminidase higher in Forest fungal pathway enhancement
Anattempt of conclusion…… Forest: more microbes (data fromothergroup) butlower LICOR measurements and lowerenzymeactivity Zzzzzzz
