Noun

dissimilation (countable and uncountable, plural dissimilations)

2. The act of dissimilating, of making dissimilar.
4. (microbiology) A dissimilatory process supplying a cell with energy only without assimilation of nutrients. An exergonic process of the microbial catabolic metabolism in which redox-active species participate in oxidation-reduction reactions (exchange of electrons) to deliver the energy needed for sustaining the cell activity. The external substances absorbed by the cell from its environment for producing energy are not assimilated for the synthesis of biomolecules or the fabrication of cell components, but excreted out of the cell after the energy production.
6. (phonology, phonetics) A phenomenon where one of a pair of similar adjacent consonant or vowel sounds in a word becomes less similar.
