Both media were supplemented with trace elements, salts and vitamins according to the procedure described by Stams et al. [ 33]; yeast extract was added to a final concentration of 0.5 g L-1.
To attribute this activation to a specific trace element, media with limited amounts of trace elements were supplemented with each of the single trace elements FeSO4, ZnSO4, CuSO4, MnCl2, Na2MoO4, CoCl2, and H3BO3.
Cultures of acetylene fermenters were grown on mineral salts media with added SL10 trace elements (Widdel et al., 1983) and vitamins (Oremland et al., 1994) with cysteine-HCl (SFB93) or Na2S (SV7) as reducing agent (Table 1).
The advantage of social media traces with respect to other sources of digital information is that they can be publicly accessed and at a very low cost.
It is likely that screening in media with more physiological pH or trace nutrient levels, with altered carbon sources [ 28], or with host defense constituents (for example, serum) in place would result in the identification of different scaffolds as promising therapies even from the same chemical libraries.
Defined media was prepared as defined nitrogen limited (NL) and nitrogen sufficient (NS) media including basal media, minerals (trace elements) and vitamins along with carbon and nitrogen sources.
E. coli cultures were grown aerobically in M9 media (glucose, trace vitamins and minerals) supplemented with either N-, 50% N- or N-labeled ammonium sulfate as the only source of nitrogen.
"Trace amounts of this mixed with trace amounts of that can equal what?
Same goes with trace amount of gak.
Growth media contains trace NaCl (2 mM).
