Abstract. Thin-layer drying studies have been done for various materials, including vegetables, fruit, grains, wood, plants, biomass, and others. The present study is concerned with the investigation of the drying kinetics of harvested photosynthetic non-sulfur bacteria (PNSB) biomass. Four different drying models, i.e., Logarithmic, Newton, Page, and Henderson and Pabis were fitted to the experimental data obtained from drying a thin-layer of biomass in a laboratory oven at 60, 80, 100, and 120 ℃. The results were assessed on statistical parameters such as the Akaike information criterion, and residual standard error. The results showed that Logarithmic model fitted the overall best for all the states of the thin layer at 60 ℃ and 80 ℃, while Page model gave the best fit for 100 ℃ and 120 ℃. The current research is aimed to study the drying behavior of the biomass and to aid in optimizing the drying procedure of the biomass.
