The phrase "as optimal concentration" is not correct in standard written English.
It may be intended to describe a level of concentration that is considered optimal, but the phrasing is awkward and unclear.
Example: "The solution should be mixed until it reaches as optimal concentration for the best results."
Alternatives: "at the ideal concentration" or "for maximum concentration".
Concerning the α-amylase concentration sufficient to reach the industrial requirements, i.e. dextrose equivalent 6 12% in 3 h, one unit of enzyme activity at defined conditions per mg starch can be considered as optimal concentration with 10% starch suspension.
To that end, 10%% w/w of ZnO/GO nanocomposite was selected as optimal concentration.
It is concluded from the above results that the 2% Poloxamer 188 was determined as optimal concentration.
Our data confirmed that partial digestion of high molecular weight DNA with the restriction enzyme HindIII (1 2 U/plug as optimal concentration) was critical to produce fragments with a good size range, leading to a good quality of the BAC library containing fragments with acceptable insert sizes, important for future whole genome study.
From the perspective of a selective leaching of zinc, where no iron is passing into the solution, concentration 0.1 M H2SO4 at L S ratio = 50 and 0.25 M H2SO4 at L S ratios = 20 and 10 can be considered as optimal concentrations.
For the different configurations that were identified, all gas flow rates can be calculated in terms of other process parameters such as optimal concentrations of the gaseous compounds in the liquid phase, top pressures of the fermentation, and consumption/production rates.
Based on these data, we chose 0.5 mM DSP and 0.5 mM DTME as optimal concentrations for subsequent experiments.
Dyes were administered via the jugular vein catheter and studied at equimolar dosages (14 pmol/g body weight) which have been identified as optimal concentrations for intravital microscopy in preliminary studies (data not shown).
The results indicate that turmeric significantly increases the activity of total SOD at optimal concentrations, as determined by the nitro blue tetrazolium (NBT) reduction assay and native-PAGE and 2(b)).
Here, 1.0 ppb is not selected as the optimal concentration as in previous cases because of the gel strength which is significantly high at the highest concentration as this would require high pump pressures for recirculation in case of pump shut down during fishing operations.
As a result, 10% DGL has been determined as an optimal concentration.
