Abstract
Spirulina platensis is a single-cell blue-green alga which belongs to the family Oscillatoriaceae. S. platensis can grow in polluted water and it has been widely used to remove excess nitrate-nitrogen and total phosphorus content in wastewater from noodle factories. This study was aimed to investigate the effect of wastewater on growth of S. platensis and to examine its potential to reduce nitrate-nitrogen and total phosphorus contents in wastewater from fermented rice noodle factory. Twenty five percentwastewater mixed arrouk’s medium gave rise to the highest growth rate of S. platensis. Optical density (OD) of S. platensis culture increased from 0.07±0.04 to 0.24±0.12. Also, the results exhibited the least value of nitrate-nitrogen and total hosphorus contents when performed in 25 % and 100 % wastewater-mixed Zarrouk’s media, respectively.
