The phrase "as a carbon source at" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing the role of a substance in providing carbon for biological or chemical processes.
Example: "The bacteria were able to utilize glucose as a carbon source at optimal growth conditions."
Alternatives: "as a source of carbon in" or "serving as a carbon source in".
This strain does not use L-alanine as a carbon source at 28C or 42C.
Methane and acetylene were used as a carbon source at flow rates between 15 and 100 sccm.
The thermotolerant yeast Kluyveromyces marxianus grows well with xylose as a carbon source at elevated temperatures, but its xylose fermentation ability is weak.
The performance of a submerged moving bed biofilm reactor (MBBR) for the denitrification of seawater in a 3.25 million l closed circuit mesocosm was investigated at pilot scale, using methanol as a carbon source at various C/N ratios.
Finally, high content of Fe impurity (ca. 12.6 wt%) remained in the porous structure of the zeolite 13X, enabling uniform growth of multi-wall carbon nanotubes (MWCNTs) by chemical vapor deposition in a quartz reactor using acetylene as a carbon source at 700 °C.
So it can be concluded that when sodium lactate was used as a carbon source at temperature 37 °C and time 7 days, maximum ORP, pH and soluble COD removal attained were −398, 8.06, and 55.5 %, respectively.
Figure 7 shows the phylogenetic placement of three isolates obtained on heterotrophic (yeast extract as a carbon source) media at 37°C from the mine (SB6 and SB37) that are very closely related to previously characterized organisms (S. thermosulfidooxidans VKM and S. disulfidooxidans) and clones (see below, BW7).
Standard conditions for S. cerevisiae consist of rich medium containing 2% glucose as a carbon source (YPD), at 30°C; in general, these standard conditions are implicit and only differences from these conditions are recorded.
For isolating individual bacteria from the consortia, 0.1 ml of inoculum was taken from 21 days grown culture media and plated on M7 agar plates, with heavy crude oil as a carbon source, and incubated at 40 °C for 7 12 days.
It has been reported that P. ostreatus grown on agar with starch as a carbon source presented two isoenzymes at an initial pH of 6.5 (Téllez-Téllez et al. 2005).
The bacterial strains and plasmids used in this study are listed in Additional file 9. R. leguminosarum strains were grown in an energy-rich 79CA medium with 1 % glycerol as a carbon source and TY medium at 28 °C on a rotary shaker (160 rpm) as described previously [ 42].
