“…Soil fungi play key roles in nutrient cycling and the functioning of terrestrial ecosystems (Torsvik and Øvreås 2002;Frąc et al 2018;Peng et al 2020;Zhou et al 2020). To date, only a few fungal taxonomic studies are available from tropical forest soil (Sato et al 2015;Amma et al 2018;Cordeiro et al 2020;Lima et al 2020). Taxonomic studies on these groups are even scarcer in Southeast Asia despite the region harboring extraordinary genetic diversity (Amma et al 2018).…”

“…It is an early-diverging fungal group in a basal position with respect to Ascomycota and Basidiomycota in the fungal tree of life (Spatafora et al 2016;Nicolás et al 2020). The order comprises 55 genera with over 260 species (Walther et al 2019;Cordeiro et al 2020;Lima et al 2020;Nicolás et al 2020;Wijayawardene et al 2020;Hurdeal et al 2021). However, for the majority of these species, their ecological roles and geographical distributions are unknown.…”

“…However, morphology-based classification of Mucor is highly debated. For example, previous literature used rhizoids to demarcate Rhizomucor from Mucor (Lima et al 2020;. Contrary to this, recent studies have revealed that some species of Mucor produce rhizoids (Lima et al 2018;.…”

Mucor species are common fast-growing fungi found in soil. Two new species of Mucor and one new geographical record of M. nederlandicus were collected from northern Thailand and are described in this study. Evidence from morphophysiological data and phylogenetic analysis supports the introduction of the new taxa. Phylogenetic analysis based on the internal transcribed spacer (ITS) and large subunit of the nuclear ribosomal RNA (LSU) data showed that the new isolates cluster distinctly from other Mucor species with high or maximum bootstrap support. Mucor aseptatophorus is characterized by aseptate sporangiophores, globose columella, resistant and deliquescent sporangia, has sympodial, and monopodial branches and shows growth at 37 °C. It also differs from M. irregularis in having smaller sporangiospores, and larger sporangia. Mucor chiangraiensis has subglobose or slightly elongated globose columella, produces hyaline sporangiospores, and resistant and deliquescent sporangia. Furthermore, this species has wider sporangiophore, smaller sporangia and lower growth than M. nederlandicus. A detailed description of the species and illustrations are provided for the novel species.

Multimetal bioremediation from aqueous solution using dead biomass of Mucor sp. NRCC6 derived from detergent manufacturing effluent

et al. 2023

Among ten metal-tolerant fungal isolates obtained from the microbiomes of detergent industry effluent, Mucor sp. NRCC6 showed the highest tolerance and an adaptive behavior toward the heavy metals Ni2+, Pb2+, Mn2+, and Zn2+. It gave the highest growth rates 0.790 ± 0.59, 0.832 ± 0.32, 0.774 ± 0.40, and 0.741 ± 1.06 mm/h along with the lowest growth inhibition 9.19, 4.37, 11.04, and 14.83% in the presence of Pb2+, Zn2+, Ni2+, and Mn2+, respectively, at a concentration of 5.0 g/L. Then, Mucor sp. NRCC6 was selected as a biotrap for the removal of these heavy metals. The optimized operating conditions were detected to be pH 6.0 for Pb2+, Zn2+, and Mn2+ and pH 5.5 for Ni2+ at 30 °C; agitation speed 150 rpm; contact time 30 min for Mn2+ and Ni2+, 30–60 min for Pb2+, and 90–180 min for Zn2+; NRCC6 biomass dosage 5.0 g/L for Ni2+ and Pb2+ and 10.0 g/L for Mn2+ and Zn2+; and initial concentration 12 mg/L of each ion in the multimetal aqueous solutions. Under these optimized conditions, the adsorption capacity for Pb2+, Ni2+, Mn2+, and Zn2+ reached 98.75, 59.25, 58.33, and 50.83%. The Langmuir isotherm was the best for describing the adsorption of Zn2+ (0.970) and Mn2+ (0.977). The Freundlich isotherm significantly giving a good fit to the adsorption of Pb2+ (0.998) while the adsorption of Ni2+ onto NRCC6 biomass can follow DKR (0.998). Furthermore, the current study revealed that Mucor sp. NRCC6 fungus is a new efficient and eco-friendly method that revealed a maximum removal of 100% for Pb2+ and Zn2+ as well as 97.39, 88.70, 78.95, 74.0, 70.22, 68.57, and 60.0% for Ni2+, Mn2+, Cd2+, Cu2+, Fe3+, As2+, and Cr6+ from the industrial wastewater, respectively.
