The remaining 30 substances comprised a mix of unbranched and methyl-branched alkanes and alkenes, 16 of which differed qualitatively between supercolonies (i.e. compounds that were present in the CHC profiles of one or several supercolonies while being absent in others, Fig. 4).
The qualitatively differing substances comprised different compound classes such as alkanes, alkenes, methyl-branched alkenes as well as mono-, di- and trimethyl-branched alkanes of varying chain length (Fig. 4), as would be expected if supercolonies diverge in a drift-like process of neutral evolution.
Other caustic substances such as pesticides, caustic food, drugs, and other substances comprised the rest of the cases.
The fermentation performance of yeast is varied by the complexity and variety of substances comprising lignocellulosic materials.
These substances, comprising hormones, cytokines, chemokines, and fatty acids, can be secreted by adipocytes, but also by macrophages, mast cells, or other cells within adipose tissue.
