However, fermentation alone cannot produce enough energy to carry out the basic functions of life. 1. 3) was more rounded with cells being almost as wide as long (cell length/width ratio of 1. However, its genome was arranged in linear chromosomes wrapped around histones which are contained within the nucleus. Most studies of these enzymes in eukaryotes involve pathogenic anaerobes; Monocercomonoides, an oxymonad belonging to the eukaryotic supergroup Excavata, is a nonpathogenic anaerobe representing an evolutionarily and ecologically distinct sampling of an anaerobic glycolytic pathway.

The protist Monocercomonoides, an inhabitant of vertebrate digestive tracts, appears to be an exception; it has no mitochondria and its genome contains neither genes derived from mitochondria nor nuclear genes related to mitochondrial maintenance. Surprisingly, despite the total lack of mitochondria in Monocercomonoides, we detected apoptosis-associated genes such as a NUC1 nuclease, two metacaspases. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species. In vitro import is a classic method to examine the ability of a protein to be imported into a specific organelle (figure 1a). Instead of mitochondria, Monocercomonoids use a sulfur modulator system for energy production that can adapt to their habitat (because Monocercomonoids are endoparasites). Mitochondria and mitochondrial DNA (mtDNA) have been of particular interest to researchers in recent years. In 2016, scientists published the genome of Monocercomonoides, and demonstrated that this organism has no detectable mitochondrial genes.
