While Deleuze explored the temporalities of alcoholism in American literature in The Logic of Sense, and Jean Clet Martin, among others, has extended this inquiry by further extracting the alcoholic’s lines of flight from the same literature, this chapter breaks the mould by understanding alcohol, distilled and in its pure form of ethanol, as well as its imbibition, as a question of a component that passes through anthropocentric, and across multiple non-anthropocentric assemblages. The exploitation of ethanol fermentation, for example, exists across species. Indeed, as we entertain more overtly human cultural examples, such as ‘wine’ for cats, a recent Japanese pet trend, the metabolic communion of interspecies companionship requires that the material expressivity of the substance is overcoded because the ‘wine’ is not only non-alcoholic but liquid catnip in a ‘wine’ bottle. Indeed, theorization of the pursuit of shared pleasures – using Guattari’s ethological terms, we might say deterritorializing from deterministic biological factors yet also modifying these in some measure as well (Machinic Unconscious) – and engaging multiple species is this chapter’s goal, achievable by plotting the passages of alcohol and its related components across assemblages and their material and socio-cultural expressive trajectories beyond strictly anthropocentric and Western prerogatives.

AbstractThe novel extremophilic yeast Rhodotorula frigidialcoholis, formerly R. JG1b, was isolated from ice-cemented permafrost in University Valley (Antarctic), one of coldest and driest environments on Earth. Phenotypic and phylogenetic analyses classified R. frigidialcoholis as a novel species. To characterize its cold-adaptive strategies, we performed mRNA and sRNA transcriptomic analyses, phenotypic profiling, and assessed ethanol production at 0 and 23 °C. Downregulation of the ETC and citrate cycle genes, overexpression of fermentation and pentose phosphate pathways genes, growth without reduction of tetrazolium dye, and our discovery of ethanol production at 0 °C indicate that R. frigidialcoholis induces a metabolic switch from respiration to ethanol fermentation as adaptation in Antarctic permafrost. This is the first report of microbial ethanol fermentation utilized as the major energy pathway in response to cold and the coldest temperature reported for natural ethanol production. R. frigidialcoholis increased its diversity and abundance of sRNAs when grown at 0 versus 23 °C. This was consistent with increase in transcription of Dicer, a key protein for sRNA processing. Our results strongly imply that post-transcriptional regulation of gene expression and mRNA silencing may be a novel evolutionary fungal adaptation in the cryosphere.
