Isolation and Characterization of Three Unrecorded Zygomycete Fungi in Korea: Cunninghamella bertholletiae, Cunninghamella echinulata, and Cunninghamella elegans

Abstract

In a survey of undiscovered taxa in Korea, three zygomycete fungal strains–EML-W31, EML-HGD1-1, and EML-RUS1-1–were isolated from freshwater, grasshopper fecal, and soil samples in Korea. On the basis of the morphological characteristics and phylogenetic analysis of internal transcribed spacer and 28S rDNA, the isolates of EML-W31, EML-HGD1-1, and EML-RUS1-1 were confirmed to be Cunninghamella bertholletiae, Cunninghamella echinulata, and Cunninghamella elegans, respectively. These species have not been previously described in Korea.

Isolation and Characterization of Three Zygomycetous Fungi in Korea: Backusella circina, Circinella muscae, and Mucor ramosissimus

“…To date, few studies have reported new and undescribed zygomycetous fungi in Korea [10,23,34,35]. Particularly, species of Backusella and Circinella are rarely found in Korea.…”

Five New Records of the Family Aspergillaceae in Korea, Aspergillus europaeus, A. pragensis, A. tennesseensis, Penicillium fluviserpens, and P. scabrosum

“…For by-products of rice bran and water samples, we used the serial dilution plating method as described by Nguyen and Lee [28] and Nguyen et al [29]. Individual colonies with various morphologies were collected, transferred to PDA, and subcultured until pure mycelia were obtained.…”

Cunninghamella bertholletiae’s Toxins from Decomposing Cassava: Mitigation Strategy for Toxin Reduction Using Nepenthes mirabilis ‘Monkey Cup’ Digestive Fluids

“…These microorganisms include the fungus, Cunninghamella bertholletiae (also known as Cunninghamella polymorpha due to its morphological characteristics and mating/reproductive scheme) [4], is known to be pathogenic to humans and animals [5][6][7], while its toxins in the environment and on consumable commodities constitute an environmental hazard and a health risk to consumers [8][9][10][11]. Some fungi, including their metabolites, are able to contaminate several plant parts as they are endophytes, culminating in infestation of agricultural products such as tomatoes, maize, potatoes, beans, peanuts, yams and wheat, including cassava [1, 5,[12][13][14][15][16][17] and dairy products such as milk and cheese [1, 18,19].…”
