About this Research Topic
There is considerable interest in pure and applied studies of extremophilic microorganisms, including those (acidophiles) that are active on low pH environments. A recently-published (2016) textbook on the topic (Acidophiles: Life in Extremely Acidic Environments, edited by R. Quatrini and D.B. Johnson, and published by Caistor Academic Press) gave a comprehensive account of the history and current status of this topic. Like many other areas of microbiology, this is a fast-developing field, and this special topic of Frontiers highlights many of the more recent advances that have been made. Leading research scientific groups working in this field have contributed a wide variety of specific subjects, ranging from molecular biology, through to physiology, environmental impact and biotechnology.
Of the ten original research articles, five (authored by González et al., Mamani et al., Mühling et al., Nuñez et al., and Patricya Florentino et al.,) focus broadly on molecular/genomic studies while the other five (authored by Blake II et al., Dopson et al., Johnson et al., Wang et al. and Hedrich et al.) are concerned with physiological, biochemical and applied aspects of acidophile microbiology.
