Abstract

The growth performance of Scenedesmus obliquus was studied in the laboratory in different concentration of sweetmeat factory waste media (SFWM). Four different concentrations viz. 1.5, 2.0, 2.5 and 3.0% of SFWM and Bold basal medium (BBM) as control was used with three replications for a period of three months. Each trial was done for a period of 14 days in the laboratory. The initial density of Scenedesmus obliquus was 2.1×105 cell/ml which attained a maximum density of 136.30×105 cell/ml in BBM followed by 97.05, 83.21, 65.19 and 51.21 (×105 cell/ml) in 2.5, 0.3, 2.0 and 1.5 % SFWM respectively on the 10th day of culture. Highest chlorophyll a content was also observed on the 10th day of culture with value of 6.14 and 5.52 mg/l in BBM and SFWM, respectively. The specific growth rate (SGR, m/day) and total biomass were significantly (P<0.05) higher in BBM than all other treatments. The overall growth performance of the alga Scenedesmus obliquus was significantly (P<0.05) higher in 2.5% SFWM than other concentrations of SFWM. The cultured microalgae were found nutritionally rich. During the whole culture period the pH range was 7.03 to 8.05. The other physico-chemical parameters of the culture media were found within the suitable range of the microalgae culture.
