Abstract :
In this research specific growth and chlorophyll of Spirulina platensis has been measured in differentorganic media (fruit died skin, cattle manure and poultry manure) and convey media as control in 15pptsalinity, 25°C temperature, pH=7, 3000 lux light, photoperiod 12h and aeration for 24h by triplicate inlaboratory. Cell concentration has been determined by spectrophotometer in 620nm wave length forspecific growth and 664,647 and 630nm for chlorophyll amount diurnal. According to results, the highestspecific growth rates was 0.0799 division day-1 at poultry manure while cattle manure and convey wereLowest 0.0023 division day-1 without any significance difference(p
