Extremely acidophilic filamentous fungi are more prevalent in diverse ecosystems than previously documented.

ABSTRACT: The study of extremophiles can lead to the discovery of highly tolerant enzymes of value to biotechnology, and extreme environments are typically sampled to facilitate their discovery. Here, we show that extreme acidotolerant filamentous fungi, able to grow at pH < 1, can be found when sampling highly diverse environments, from industrial sites with low pH to typical non-acidic plant and soil samples. Over 100 fungal strains were isolated from over 2,000 samples taken from across Vietnam, and many of the strains were able to grow over wide pH ranges, displaying either acidotolerance or clear acidophilicity. ITS sequencing revealed that 63 isolates represent 12 previously undescribed species, with the majority from the Talaromyces or Penicillium genera. We furthermore report the rediscovery
