4. Results and Discussions ---The main target of this research was to find out the ethanol presence in the solution that means the establishment of ethanol production procedure from spirulina it can be easily said that our result is positive. And this research is According to this successful. Although our main objective was to set up a definite process for ethanol production from micro algae spirulina by using its carbohydrate content but we had a secondary objective of process standardization. We have made various samples to fulfill our secondary objective. Four types or sample variation were done by us.
4.1 Air drying time variation --- it is seen that we have got the highest percentage ethanol with the sample solution of 3 days air drying Three sample given in Table 01. The reason may behind this the moisture content. As the moisture content was reduced in the algal powder so the finer algal powder was made. As a result the solution became more fermentable and ethanol percentage was increased. Graphical presentation of those data is given in Figure 01
4.2 Sulphuric acid concentration variation and ---Three samples were made with the variation of Sulphuric acid concentration Those were with l 1.5 the acid. Three sample data are given in Table 02. The results show highest ethanol obtain concentration in 2% Sulphuric acid. The basic reason behind this is the higher concentration of Sulphuric acid the reducing sugar solution also goes high. presentation ofthose data is given Figure 02.
