Description

Collection and processing of biofilm samples from natural and artificial substrates to quantify biomass, algal content, and nutrient content through AFDM, chlorophyll-a, and phosphorus analysis.

Typical Equipment

  • nylon Smoker's toothbrush
  • ImageJ2 software
  • 25 mm Pall AE filters
  • MgCO3 buffered 90% ethanol
  • Turner Designs Trilogy Fluorometer Model #7200
  • K2S2O8

Output Measurements

  • biofilm AFDM
  • chlorophyll-a concentration
  • percent phosphorus
  • Chl-a to AFDM ratio
