Investigation On Relationships Between Optical Properties And Cell Concentrations Of Microalgae, Zhaoming Zhou

Graduate Theses & Non-Theses

Biofuel from microalgae is a very promising renewable energy resource. Growth of microalgae depends on ambient temperature, appropriate nutrients in water, and light condition for photosynthesis. As microalgae grow, the depth of light penetration decreases and the growing conditions at depth deteriorate. Monitoring of microalgae concentration during their growing phase is imperative to ensure efficiency in biomass production. Conventionally, cell concentration (number of cells per unit volume) of microalgae solution is estimated by taking images of samples under microscope and then counted and estimated using the Metallized Hemacytometer Hausser Bright-Linewe (MHHBL) method developed by Hausser Scientific. This method of measuring …
