Insights

Six fungal strains from Korean freshwater and sediment samples were identified. Four species of Mucorales, including Mucor abundans, were newly reported in Korea based on morphological and molecular data.

Area of Science:

  • Mycology
  • Environmental Microbiology
  • Molecular Biology

Background:

  • Fungi, particularly those in the order Mucorales, play crucial roles in freshwater and sediment ecosystems.
  • Understanding fungal diversity is essential for ecological assessments and biotechnological applications.

Purpose of the Study:

  • To isolate and identify fungal strains from freshwater and sediment samples in Korea.
  • To characterize the morphological and phylogenetic features of the isolated strains.
  • To report novel occurrences of Mucorales species in Korea.

Main Methods:

  • Isolation of fungal strains from environmental samples (freshwater and sediment).
  • Morphological characterization of fungal isolates.
  • Molecular phylogenetic analysis using the internal transcribed spacer (ITS) region.

Main Results:

  • Six strains of fungi belonging to the order Mucorales were successfully isolated.
  • Isolates NNIBRFG6649 and NNIBRFG6255 were identified as Mucor abundans and M. aligarensis.
  • Isolates NNIBRFG1498, CNUFC-YJ13, CNUFC-YR7, and NNIBRFG2739 were identified as M. moelleri and M. heterogamus.
  • This study represents the first report of M. abundans, M. aligarensis, M. moelleri, and M. heterogamus in Korea.

Conclusions:

  • The investigation expanded the known diversity of Mucorales in Korea.
  • Morphological and molecular data confirmed the identification of four distinct species.
  • These findings highlight the importance of continued mycological surveys in underexplored environments.

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Techniques for Isolation of Pure Cultures

Microorganisms are routinely cultured in the laboratory using various techniques to isolate, grow, and quantify them for further study. These methods rely on inoculating microorganisms into a suitable growth medium under aseptic conditions to prevent contamination. Depending on the objective, inoculation can involve direct transfer or the use of diluted bacterial suspensions as the inoculum.Streak-Plate Method for IsolationThe streak-plate method is a common technique for obtaining pure...
