“…However, as U. curvata have been distinguished fromU. ramanniana quite recently (Wang et al, 2022), it is difficult to compare our findings with older studies on the ecology ofUmbelopsis spp. and thus understand the observed preferences of this species.…”

Many social insect species build nests, which strongly differ from the surrounding environment and are often occupied by specific organismal communities. In temperate forests, red wood ants (e.g. Formica polyctena) are known to create such distinct, highly developed nests, which consist of large, above-ground mounds. Those structures are built primarily out of plant matter collected from the forest litter. Common fungal dwellers of forest litter are representatives of Mucoromycota, engaged in the decomposition process of this substrate. However, data on co-occurrence or interactions between these ants and fungi remains unknown. In order to elucidate these interactions we characterized Mucoromycota communities of Formica polyctena nests and the surrounding forest litter. We sampled four sites, twice in a season and used: a culturomics approach, complemented with DNA barcoding to describe fungal communities; PERMANOVA test and non-metric multidimensional scaling ordinations to compare those communities; and multilevel pattern analysis to indicate taxa associated with the mounds. Our results show that the Mucoromycota community of Formica polyctena’s mound is specific and more stable than the community of the surrounding forest litter. While representatives of Entomortierella lignicola and Absidia cylindrospora clade were found to be associated with the mound environment, representatives of Umbelopsis curvata and Podila verticillata-humilis clade were associated with forest litter, and were rarely present in the mounds. Our findings strongly suggest that the red wood ants’ nest is a specific microenvironment in the temperate forest floor, which is a preferred microhabitat for the mound-associated Mucoromycota, possibly adapted to live in close proximity to ants.

“…However, the increasing demand for natural β‐carotene leads research focus on finding new β‐carotene sources. A filamentous fungus of the family Mortierellacea, Umbelopsis ramanniana (previously known as Mortierella ramanniana ) is a member of the Zygomycetes class 22–24 . Zygomycetes fungi are recognized as producers of carotenoids and single‐cell‐oils, but more commonly as producers of gamma‐linolenic acid (GLA) 25,26 .…”

Umbelopsis ramanniana was investigated to increase carotenoid production. Nine different carbon sources and six different nitrogen sources were evaluated for the maximum carotenoid production. The most effective nitrogen and carbon sources were KNO3 and lactose, respectively. Then, the optimization of medium components for enhancement of carotenoid production by Umbelopsis ramanniana was achieved using Plackett–Burman design. Box–Behnken response surface methodology was applied to further optimize carotenoid and biomass production. Carbon to nitrogen ratio, lactose concentration, and shaking speed were studied as variables in Box–Behnken design. The optimum conditions for carotenoid and biomass production were determined as 32.42 g/L of lactose concentration, 20:1 of carbon to nitrogen ratio, and shaking speed of 130 rpm. The maximum carotenoid and biomass production under optimized conditions were 1141 μg/L (β‐carotene‐Eq) and 13.14 g/L, respectively. When compared to the control fermentation, carotenoid, and biomass production were increased by about 2 and 1.3 folds, respectively.
