a\(\text{Biomass\ }\left(Glucose,\ \ oil\right)los\ rate=\frac{c_{b}-c_{a}}{S_{\text{SLs}}}\)
Where \(c_{b}\) is the quality before separation in g, \(c_{a}\) is the quality after separation in g, \(S_{\text{SLs}}\) is the isolated SLs in g.
b\(\text{SLs\ separation\ rate}=\frac{S_{\text{SLs}}}{c_{\text{SLs}}}\)
Where \(S_{\text{SLs}}\) is the isolated SLs in g,\(\ c_{\text{SLs}}\)is the quality of SLs before separation in g.
c\(In-situ\text{\ separation\ efficiency}=\frac{S_{\text{SLs}}}{t}\)
Where \(S_{\text{SLs}}\) is the isolated SLs in g,\(\ t\) is separation of time in min.
