“…In previous findings, we showed that P. huenov can tolerate high levels of some heavy metals such as Ni, Pd, and Cd [ 24 ]. In this study, we observed that yeast cells can grow even better at low concentrations of manganese (55 mg/L), or copper (64 mg/L), since biomass (g/L) or cell density (OD) of cultures treated with these metals (12.55–12.8 g/L) was higher than that of controls (12.5 g/L) ( Figure 1(A,B) ; Table 1 ).…”

“…Investigations into the effect of manganese and copper on P. huenov were based on cell dynamic development in liquid culture according to the method, previously described [ 24 ] with some modifications. Briefly, P. huenov from the collection at the institute of Biotechnology, Hue University was inoculated into fresh YPD medium agar (1% yeast extract, 1% peptone, 2% glucose, 2% agar).…”

“…Papiliotrema yeast species are wild yeast isolated from many habitats [ 22 ] and a limited number of studies, have shown promising results for the use of Papiliotrema yeast species in bioremediation [ 23 ]. Excitingly, in our previous study we showed that Papiliotrema huenov is resistant to numerous heavy metals including Ni, Pb, As and Cd [ 24 ], can live in a wide range of temperatures and grows well in inexpensive media, making it an extremely promising candidate for bioremediation. However, two key toxic metals, copper and manganese were not previously considered in detail.…”

Papiliotrema huenov was previously reported to be highly tolerant of a range of extremely toxic heavy metals. This study aimed to identify the potential of P. huenov to remove manganese and copper from aqueous solution. Physical conditions which affect removal of Mn(II) and Cu(II) were determined. Optimal temperature for adsorption of both metal ions was 30 C, and optimal pH for maximum uptake of Mn(II) and Cu(II) were 5 and 6, respectively. Under these conditions, living cells of P. huenov accumulated up to 75.58% of 110 mg/ L Mn(II) and 70.5% of 128 mg/L Cu(II) over 120 h, whereas, the removal efficiency of metal ions by dead cells over 1 h was 60.3% and 56.5%, respectively. These results indicate that living cells are more effective than dead biomass for bioremediation, but that greater time is required. The experimental data extends the potential use of P. huenov in biosorption and bioaccumulation of toxic heavy metals to copper and manganese, two of the most common industrial contaminants.

“…Similarly, Sporobolomyces roseus can produce zeatin ( Streletskii et al, 2019 ) and degrade amino acids ( Moore et al, 1968 ). Papiliotrema has been reported to be resistant to heavy metals ( Nguyen et al, 2020 ). These biological functions possibly supply essential nutrients for the growth of cotton boll larvae or aid the host in detoxification processes.…”

Yeast is one of the important symbiotic flora in the insect gut. However, little is known about the gut yeast in Helicoverpa armigera (Lepidoptera: Noctuidae) under various dietary conditions. The composition and function of the intestinal yeast community also remain unclear. In this research, we explored the composition of yeast microorganisms in H. armigera larvae under different feeding environments, including apple, pear, tomato, artificial diet (laboratory feeding), Urtica fissa, Helianthus annuus, and Zinnia elegans (wild environment) using high-throughput sequencing. Results showed that a total of 43 yeast OTU readings were obtained, comprising 33 yeast genera and 42 yeast species. The yeast genera with a total content of more than 5% were Hanseniaspora (36.27%), Moesziomyces (21.47%), Trichosporon (16.20%), Wickerhamomyces (12.96%) and Pichia (6.38%). Hanseniaspora was predominant when fed indoors with fruits, whereas Moesziomyces was only detected in the wild group (Urtica fissa, Helianthus annuus, Zinnia elegans) and the artificial diet group. After transferring the larvae from artificial diet to apple, pear and tomato, the composition of intestinal yeast community changed, mainly reflected in the increased relative abundance of Hanseniaspora and the decreased abundance of Trichosporon. Simultaneously, the results of α diversity index indicated that the intestinal yeast microbial diversity of H. armigera fed on wild plants was higher than that of indoor artificial feeding. PCoA and PERMANOVA analysis concluded that there were significant differences in the gut yeast composition of H. armigera larvae on different diets. Our results confirmed that gut yeast communities of H. armigera can be influenced by host diets and may play an important role in host adaptation.

In this study, twenty-five yeast strains were isolated from soil samples collected in the gold mining ore in Gia Lai, Vietnam. Among them, one isolate named GL1 T could highly tolerate Cu 2+ up to 10 mM, and the isolates could also grow in a wide range of pH (3–7), and temperature (10–40 °C). Dried biomass of GL1 was able to remove Cu 2+ effectively up to 90.49% with a maximal biosorption capacity of 18.1 mg/g at pH 6, temperature 30 °C, and incubation time 60 min. Sequence analysis of rDNA indicated this strain was closely related to Rhodotorula mucilaginosa but with 1.53 and 3.46% nucleotide differences in the D1/D2 domain of the 28S rRNA gene and the ITS1-5.8S rRNA gene-ITS2 region sequence, respectively. Based on phylogenetic tree analysis and the biochemical characteristics, the strain appears to be a novel Rhodotorula species, and the name Rhodotorula aurum sp. nov. is proposed. This study provides us with more information about heavy metal-tolerant yeasts and it may produce a new tool for environmental control and metal recovery operations.
