In this study, we were driven by the following questions regarding the heterotroph/Prochlorococcus interactions: is the removal of HOOH from the medium necessary and sufficient for the helping phenotype?
The diversity of combinatorial interactions of medium components with the metabolism of cells as well as the large number of medium constituents necessary for cellular growth and production do not permit satisfactory detailed modelling.
In order for this to be a successful spy camera, of course, it needs more than just an imaging component — a storage and transmission medium are necessary for any camera to be useful.
Furthermore, it could be shown that in addition to the present basal salts of the sugar beet molasses the TKI medium is necessary for optimal growth of B. bassiana.
In our study, both ABA and light spectra experiments, control calli also showed somatic embryos indicating that medium with 2,4-D initiated the necessary physiological changes in the calli during subcultures, however, withdrawal of 2,4-D from the medium was necessary for the development of somatic embryos.
The conclusion warranted from this evidence is that no particular medium is necessary for a revolution: We know you can have a revolution without, say, telephones because we've had many such revolutions.
Generally, an excess of carbon substrate and a limiting amount of nitrogen in the medium are necessary for achieving high lipid accumulation in a microorganism [ 26].
That is, we are able to reproduce here the NB phenomenology in its entirety using only serum and without the need for the prolonged incubations in cell culture medium previously deemed necessary for the growth and demonstration of NB.
Interestingly, growth of C. albicans within the liquid medium was not necessary for nematode death, as filaments of C. albicans were seen extruding from some dead nematodes despite no in vitro growth, suggesting the compound inhibited the fungus in vitro but not in vivo.
