The growth performance of Spirulina platensis was studied in four different concentrations viz. 0.3, 0.4, 0.5 and 0.6 g/l of papaya (Carica papaya) skin powder media (PSPM) and in control, Kosaric Medium (KM) in triplicate. The initial cell weight of S. platensis was 6.0 mg/l which attained a maximum weight of 913.13 mg/l on the 10th day of culture in the control KM followed by 699.07, 612.13, 538.99 and 377.48 mg/l that grown in 0.40, 0.30, 0.50 and 0.60 g/l of PSPM respectively. Similar trend was observed in the case of chlorophyll a content ranging 3.57 to 8.15 mg/l. The specific growth rate (SGR, μ/day) of S. platensis on the basis of cell weight and chlorophyll a content was recorded in the ranges of 0.41 to 0.50 and 0.41 to 0.49, respectively, for all the treatments. The SGR on the basis of cell weight and chlorophyll a was recorded significantly (p<0.05) higher in KM among all the treatments. On the other hand among the four different concentrations of PSPM, 0.40 g/l showed significantly (p<0.05) higher SGR than others. The pH and other physico-chemical factors were within suitable range of algae culture. The cultured microalga was nutritionally rich.

The growth performance of green alga, Chlorella ellipsoidea was studied in a laboratory in different concentrations of fertilizer factory effluent media (FFEM). Five different concentrations viz. 40, 45, 50, 55 and 60% of FFEM and bold basal medium (BBM) (control) were used with three replications for a period of three months. Each trial was done for a period of 16 days. The initial cell density of C. ellipsoidea was 2.5×105 cells.ml-1 which attained a maximum density of 198.49x105 cells.ml-1 in BBM followed by 182.07, 157.41, 142.34, 137.57 and 121.35 (x105 cells. ml-1) in 50, 55, 45, 60 and 40 % FFEM, respectively on the 10th day of culture. A similar trend was observed in the case of chlorophyll a content and the range was 5.85 to 9.39 mg.l-1. The specific growth rate (SGR, μ.day-1) on the basis of cell number and chlorophyll a were found at 0.40 to 0.44 and 0.41 to 0.45, respectively and was significantly (p<0.05) higher in BBM. The total biomass was found at 629.13 and 541.36 mg.l-1 in BBM and 50% FFEM, respectively. The overall growth performance of C. ellipsoidea was significantly (p<0.05) higher in 50% FFEM than in other concentrations of FFEM. The cultured microalga was found nutritionally rich.

An experiment was conducted to evaluate growth performances and production of bio-fuel of Spirulina platensis (Gomont), and bio-oxygen and bio-electricity of culture media in supernatant of three different amount of digested poultry waste (DPW), and Kosaric medium (KM) as control. Three different amounts (concentrations) such as 2.0, 4.0 and 6.0 g/L poultry waste were allowed to digest under aeration. After 17 days, 700 ml grayish coloured supernatant was taken with addition of 9.0 g/L NaHCO3 and 0.50 ml/l micronutrient in 2.0 L conical flask with three replications and then autoclaved. Spirulina was inoculated to grow in these three treatments including KM (Control) after 72 hours of autoclave and then allowed to grow for a period of 14 days. This duration was estimated through repeated growth trials. The cell weight of spirulina was attained a maximum of 12.58 ± 1.25 mg/L (dry wt. basis) in KM followed by 11.46 ± 1.03, 9.16 ± 0.84 and 8.13 ± 0.73 mg/L in supernatant of 4.0, 2.0 and 6.0 g/L DPW, respectively on the 10th day of culture. Similar trend was also observed in the cases of optical density of the media contained spirulina, chlorophyll a content (mg/L), cell weight, total biomass (mg/l) and specific growth rates on the basis of cell weight and chlorophyll a. Cell weight of spirulina grown in these media had highly significant (P < 0.01) correlation with the chlorophyll a content (r = 0.993) of spirulina. Crude protein of spirulina grown in supernatant of DPW was lower than that of spirulina cultured in KM. Crude lipids as bio-fuel of spirulina cultured in supernatant of 4.0 g/L DPW was almost three times higher than that of spirulina grown in KM which may be due to high phospholipids bioaccumulation. Phosphate-P was decreased in media of DPW due to its use for high lipids biosynthesis as phospholipids. Bio-oxygen was produced higher ranged from 2.1 ± 11 mg/L on initial day to 10.20 ± 0.54 mg/L on 10th day grown in supernatant of 4.0 g/L DPW media. Bio-electricity as green electricity ranged from 135 ± 4 on initial day to 284 ± 7 mV on 10th day when spirulina cultured in supernatant of 4.0 g/L DPW which was higher than grown in other media. pH followed the similar trend like bio-oxygen and bio-electricity. It was found that the production of bio-oxygen, bio-fuel and bio-electricity had direct relation with pH in culture media of spirulina. Therefore, mass production of Spirulina platensis might be done in supernatant of 4.0 g/L digested poultry waste to get high total lipids as bio-fuel, bio-electricity and bio-oxygen.

An experiment was conducted for the production of protein, bio-fuel and bio-electricity from the culture system of Spirulina platensis (Gomont) in supernatant of three different amount of digested rotten tomato (Solanum lycopersicum), and Kosaric Medium (KM) as control. Three different concentrations such as 25, 50 and 75% rotten tomato were allowed to digest under aeration. After 17 days, the colorless supernatant was screened and taken in 1.0 L conical flask with three replications. Then, Spirulina platensis was inoculated to grow in these three media (treatments) with the addition of 9.0 g/L NaHCO3 and micronutrients, and also in KM as control for a period of 14 days. The cell weight, optical density, chlorophyll a and total biomass of spirulina was attained to the maximum values when grew in KM on the 10th day of culture followed by supernatant of 50% digested rotten tomato (DRT) than in 25 and 75% DRT culture. The chemical properties of the culture media such as pH, salinity, dissolved bio-oxygen, electric conductivity and bio-electricity were increased from first day up to 12th day of experiment. Total biomass of spirulina grown in these media had highly significant (P < 0.01) correlation with cell weight (r = 0.825) and chlorophyll a (r = 0.866) of spirulina. The results showed that the growth performances of S. platensis grown in supernatant of 50% DRT was significantly (P < 0.01) higher than that of spirulina grown in supernatant of 25 and 75% DRT. The percentage of crude protein (55.10 ± 0.45 to 59.90 ± 0.33%) of spirulina grown in supernatant of DRT was little bit higher than that of spirulina cultured in KM (58.40 ± 0.38%). But bio-fuel in terms of crude lipids (16.50 ± 0.31%) of spirulina cultured in supernatant of 50% DRT was almost two and half times higher than that of spirulina grown in KM (crude lipids, 6.30 ± 0.21%). Bio-electricity (300 ±10.20 mV) produced in culture of spirulina in supernatant of 50% DRT was higher than that recorded in KM (240 ±10.20 mV) followed by 75% DRT and other media. Bio-electricity had directly and strongly significant (p < 0.001) correlation with pH (r = 0.812), dissolved bio-oxygen (r = 0.832), salinity (r = 0.788) and electric conductivity (r = 0.856). Therefore, this procedure will produce huge amount of electricity in the world and will make a revolution in this field of bio-electricity production. Whole world will be benefited from the output (results) of this experiment.

Muriate Of Potash

Five media were formulated with 0% (control, T1), 25% (T2), 50% (T3), 75% (T4) and 100% (T5) inclusion of low-cost muriate of potash (MOP)-potassium (K) replacing high-cost reagent K2SO4-K and Spirulina platensis was cultured for 18 days. Cell dry weight, optical cell density and chlorophyll-a content of S. platensis cultured in five treatments were registered at every three-day interval and economic performance was calculated to observe the effect of K2SO4-K replacement with MOP-K. The cell biomass production and chlorophyll-a content of S. platensis cultured in 25 and 50% use of MOP-K instead of K2SO4-K (T2 and T3) did not represent any significant difference with the control treatment of 100% K2SO4-K (T1). However, further addition of MOP-K in T4 and T5 significantly reduced the cell growth and pigment content of S. platensis. In addition, a significant reduction of production cost was calculated as more percentage of K2SO4- K was replaced with MOP-K.
