The standardized extract was prepared by a water extraction with dried leaves of PM to plant extract ratio (1 20) using the unique best-available method of aqueous extraction technology.
Parameters affecting the formation of nanoparticles such as temperature, exposure time to extract, pH, concentration of silver nitrate, and extract (ratio of plant sample to extraction solvent) were investigated and optimized.
Seeds did not germinate in the FPR aqueous extract at 1 10 extract ratio, and GI increased when the solvent extraction ratio increased.
A similar conclusion which can be drawn from Fig. 2c is the absorption spectra of gold nanoparticles, synthesized with HAuCl4 to black cardamom extract ratio of 1 0.1.
The modeled experimental optimization for E. campestre leaf extract was found as time of 3 min, temperature of 34 °C and metal salt-to leaf extract ratio of 2.38 with predicted response of 73.17%.
Given the results, the optimal enzyme production conditions were achieved with coriander seed extract (CSE /yeast extract ratio of 16.9 w/w, olive oil (OO) and MgCl2 concentration of 2.37 g/L and 24.23 mM, respectively.
The CSE/yeast extract ratio of 16.9 w/w, OO concentration of 2.37 g/L and MgCl2 concentration of 24.23 mM, were found to be the optimal conditions of the enzyme production process.
The high extract ratio of 10.7% (i.e. 1820 mg extract/17 057 mg mycelium) as well as high content of polysaccharide (i.e. 1.12 g/l) indicated that the deproteinated whey could be an alternative substrate for mycelial production.
The high extract ratio as well as high content of polysaccharide (i.e., 1.2 g/l) indicated that the whey could be an alternative substrate for the mycelial production.
The effect of several parameters including incubation time, incubation temperature, and precursor salt to plant extract ratio was investigated in order to optimize trimetallic oxide Cu/Cr/Ni NP production.
