“…In general, yeast strains have a high tolerance to sugar with strains, such as Pichia kudriavzevii YF1702 and Clavispora lusitaniae YX3307 [ 25 , 43 , 44 , 45 , 46 ]. Additionally, like other microorganisms, yeasts have a limited tolerance to NaCl, a concentration of 15% preventing the growth of most microorganisms [ 42 , 47 ]. Compared with most other reports on yeast, strain YHM-G had a high tolerance to NaCl, so it could better adapt to different environments [ 47 , 48 ].…”

Compared with most other reports on yeast, strain YHM-G had a high tolerance to NaCl, so it could better adapt to different environments [ 47 , 48 ]. However, there are a few yeasts with a high tolerance of up to 30% NaCl screened from particular environments, possibly related to the activation of antioxidant enzymes in the antagonistic yeast, including catalase, thioredoxin reductase, glutathione peroxidase and glutathione reductase [ 49 , 50 ].…”

3-Methylthio-1-propanol (3-Met) is widely used as a flavoring substance and an essential aroma ingredient in many foods. Producing 3-Met by microbial transformation is green and eco-friendly. In the present study, one strain, YHM-G, which produced a high level of 3-Met, was isolated from the Baijiu-producing environment. Strain YHM-G was identified as Hyphopichia burtonii according to its morphological properties, physiological and biochemical characteristics, and ribosomal large subunit 26S rRNA gene D1/D2 domain sequence analysis. The optimal conditions for 3-Met production by YHM-G were obtained by single factor design, Plackett–Burman design, steepest ascent path design and response surface methodology as follows: 42.7 g/L glucose, pH 6, 0.9 g/L yeast extract, 6 g/L L-methionine (L-Met), culture temperature 28 °C, shaking speed 210 rpm, loading volume 50 mL/250 mL, inoculum size 0.5% (v/v), culturing period 48 h and 2.5 g/L Tween-80. Under these optimal conditions, the 3-Met production by strain YHM-G was 3.16 g/L, a value 88.1% higher than that before optimization. Strain YHM-G can also produce a variety of flavor compounds that are important for many foods. This strain thus has the potential to increase the abundance of 3-Met in some fermented foods and enhance their aroma profiles.

“…In another report, urease-producing bacteria Sporosarcina pasteurii, Stenotrophomonas rhizophila, and Variovorax boronicumulans isolated from the Iranian mine calcareous soils were reported for the biomineralizing various heavy metals [64]. Aibeche et al [65] have reported yeast strains including Rhodotorula mucilaginosa, Clavispora lusitaniae, and Wickerhamomyces anomalus for the remediation of heavy metals mercury, chromium, cadmium, lead, copper, zinc, and iron. These yeast strains were isolated from the lead and cadmium highly polluted area of Dayet Oum Ghellaz Lake water [Table 2].…”

The rise in environmental pollution over the past few decades due to rapid industrialization and unsafe agricultural practices has become a major challenge. The presence of toxic pollutants such as nuclear wastes, heavy metals, pesticides, and hydrocarbons has been languishing the environment as well as the human health. Bioremediation using microbial communities is emerging as an incredible, eco-friendly, and cost-effective approach to ameliorate the adverse effects of toxic pollutants. Microbes possess astonishing metabolic capabilities to alter most forms of organic material and can survive in extreme environmental conditions which make them attractive candidate for the bioremediation. Microbes are the treasure houses for environmental cleaning and recovering of contaminated soil and they have been reported from diverse environmental conditions including hot, cold, drought, and saline. Different groups of bioremediating microbes have reported from diverse conditions, that is, bacteria, fungi including yeast, and algae. Microbes belonging to genera Alcaligenes, Aspergillus, Bacillus, Flavobacterium, Ganoderma, Methosinus, Nocardia, Phormidium, Pseudomonas, Rhizopus, Rhodococcus, and Stereum have been reported as potential and efficient bioremediators for the degradation of different pollutants of the environment such as xenobiotics, heavy metals, hydrocarbons, and paper and pulp effluent. The present review focuses on microbial diversity in bioremediation, techniques applied in bioremediation, bioremediation of different environmental pollutants, and how bioremediation processes could be monitored.
