Abstract Soil microorganisms play important roles in soil quality and plant productivity. The development of effective methods for studying the diversity, distribution, and behavior of microorganisms in soil habitats is essential for a broader understanding of soil health. Traditionally, the analysis of soil microbial communities has relied on culturing techniques using a variety of culture media designed to maximize the recovery of diverse microbial populations. However, only a small fraction (
