The fungal kingdom is too large to be discovered exclusively by classical genetics. The access to omics data opens a new opportunity to study the diversity within the fungal kingdom and how adaptation to new environments shapes fungal metabolism. Genomes are the foundation of modern science but their quality is crucial when analysing omics data. In this study, we demonstrate how one gold-standard genome can improve functional prediction across closely related species to be able to identify key enzymes, reactions and pathways with the focus on primary carbon metabolism.Based on this approach we identified alternative genes encoding various steps of the different sugar catabolic pathways, and as such provided leads for functional studies into this topic. We also revealed significant diversity with respect to genome content, although this did not always correlate to the ability of the species to use the corresponding sugar as a carbon source.

“…In general, S. cerevisiae lacks several of the enzymes associated with primary carbon metabolism predicted in A. niger . In some cases, entire pathways are missing, even though growth has been described (Oliva Neto et al. 2014).…”

“…In this study, nerolidol antibacterial potency against L. fermentum (MIC: 25 μM; 5.56 mg/l) was weaker than that of gentamicin [44] and chloramphenicol [45], and close to that of novobiocin [46] and Nalkyldimethylbenzyl ammonium chloride [47] (Table 3). On the other hand, L. fermentum strains were less sensitive to well-known antibiotics including vancomycin [45,48], teicoplanin [45], streptomycin [44,45,48], erythromycin, tobramycin, clindamycin, kanamycin, polymixin B [44,46,48], metronidazole, and nitrofurantoin [49] (Table 3).…”

Essential oil components are widely used for their antibacterial activity against spoilage microorganisms in food. Lactobacillus fermentum is a Gram-positive lactic acid bacteria responsible for the deterioration of various food products, including beverages and dairy products. In this study, 17 terpenic and 11 phenolic compounds were screened against the food spoilage microorganism Lactobacillus fermentum ATCC 9338. The antibacterial activity of the tested compounds was dependent on hydrophobicity and particular chemical features. Nerolidol solubilized in dimethylsulfoxide exhibited the highest antibacterial activity and showed low minimal inhibitory (MIC: 25 μM) and minimal bactericidal (MBC: 50 μM) concentrations. Moreover, no viable cells were detected within 16 h of incubation at 50 μM. The important antibacterial activity of nerolidol against L. fermentum is probably related to the high hydrophobicity, the aliphatic chain length, and the presence of the hydroxyl group. Hydroxypropyl-β-cyclodextrin/nerolidol inclusion complex showed MIC and MBC values of 100 and 200 μM, respectively. The total bacterial kill was observed after 12 h of incubation. The results obtained with the inclusion complex are probably due to the time required to allow nerolidol to be released from the inclusion complex.
