“…There are no reports indicating that E. ashbyi might be pathogenic to humans or any other animals. However, some studies characterise it as a plant pathogen, since it has been shown to be able to cause stigmatomycosis (or ‘yeast spot’) in citrus fruit (Batra, 1973), soybean (Kimura et al., 2008a) and azuki bean (Kimura et al., 2009). A likely route of transmission to new places of infection is via stink bugs that have fed on infected plants or plant material (Kimura et al., 2008b).…”

The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre-evaluation of the safety of biological agents, intended for addition to food or feed, to support the work of EFSA's Scientific Panels. The QPS approach is based on an assessment of published data for each agent, with respect to its taxonomic identity, the body of relevant knowledge, safety concerns and occurrence of antimicrobial resistance. Safety concerns identified for a taxonomic unit (TU) are, where possible, confirmed at the species/strain or product level and reflected by 'qualifications'. In the period covered by this statement, no new information was found that would change the status of previously recommended QPS TUs. Schizochytrium limacinum, which is a synonym for Aurantiochytrium limacinum, was added to the QPS list. Of the 78 microorganisms notified to EFSA between October 2020 and March 2021, 71 were excluded; 16 filamentous fungi, 1 Dyella spp., 1 Enterococcus faecium, 7 Escherichia coli, 1 Streptomyces spp., 1 Schizochytrium spp. and 44 TUs that had been previously evaluated. Seven TUs were evaluated: Corynebacterium stationis and Kodamaea ohmeri were re-assessed because an update was requested for the current mandate. Anoxybacillus caldiproteolyticus, Bacillus paralicheniformis, Enterobacter hormaechei, Eremothecium ashbyi and Lactococcus garvieae were assessed for the first time. The following TUs were not recommended for QPS status: A. caldiproteolyticus due to the lack of a body of knowledge in relation to its use in the food or feed chain, E. hormaechei, L. garvieae and K. ohmeri due to their pathogenic potential, E. ashbyi and C. stationis due to a lack of body of knowledge on their occurrence in the food and feed chain and to their pathogenic potential. B. paralicheniformis was recommended for the QPS status with the qualification 'absence of toxigenic activity' and 'absence of genetic information to synthesize bacitracin'.

Eremothecium ashbyi is a phytopathogenic fungus infesting cotton, soybeans and several other plants. This highly flavinogenic fungus has been phylogenetically characterized, but the genetic aspects of its central metabolic and riboflavin biosynthetic pathways are unknown. An ORF of 996 bp was obtained from E. ashbyi by using degenerate primers for glyceraldehyde-3-phosphate dehydrogenase (GPD) through reverse transcriptase polymerase chain reaction (RT-PCR) and 5'-3' rapid amplification of cDNA ends (RACE-PCR). This nucleotide sequence had a high similarity of 88% with GPD sequence of Ashbya gossypii. The putative GPD peptide of 331-aa had a high similarity of 85% with the GPD sequence from other ascomycetes. The ORF had an unusually strong codon bias with 5 amino acids showing strict preference of a single codon. The theoretical molecular weight for the putative peptide was 35.58 kDa with an estimated pI of 5.7. A neighbor-joining tree showed that the putative peptide from E. ashbyi displayed the highest similarity to GPD of A. gossypii. The gene sequence is available at the GenBank, accession number EU717696. Homology modeling done with Kluyveromyces marxianus GPD (PDB: 2I5P) as template indicated high structural similarity.
