“…Other red algae, including Cyanidium caldarium, Galdieria sulphuraria , and Galdieria phlegrea , are also able to persist at maximum temperatures of 56 °C 29 – 31 . These algae have a variety of strategies that enable withstanding high temperatures, including the production of thermostable enzymes and protective extracellular polymeric substances, as well as high rates of primary production which can fuel the development of these specialized features 32 . Similar strategies, such as the production of thermostable enzymes, have also been observed in bacteria 32 .…”

Research in extreme environments has substantially expanded our understanding of the ecology and evolution of life on Earth, but a major group of organisms has been largely overlooked: microbial eukaryotes (i.e., protists). In this Perspective, we summarize data from over 80 studies of protists in extreme environments and identify focal lineages that are of significant interest for further study, including clades within Echinamoebida, Heterolobosea, Radiolaria, Haptophyta, Oomycota, and Cryptophyta. We argue that extreme environments are prime sampling targets to fill gaps in the eukaryotic tree of life and to increase our understanding of the ecology, metabolism, genome architecture, and evolution of eukaryotic life.

“…In recent years, there has been a renewed interest in these organisms leading to a significant expansion of knowledge about their taxa, properties, metabolism, and biotechnological potential (Saini et al 2021). This is particularly evident in the recent surge in the delineation of novel thermophilic taxa such as the following Thermoleptolyngbya (Sciuto and Moro 2016), Thermostichus (Komárek et al 2020), Leptothermofonsia (Tang et al 2022b), Trichothermofontia (Tang et al 2023), or Thermocoleostomius (Jiang et al 2023).…”

Thermophilic cyanobacteria are prokaryotic photoautotrophic microorganisms capable of growth between 45 and 73 °C. They are typically found in hot springs where they serve as essential primary producers. Several key features make these robust photosynthetic microbes biotechnologically relevant. These are highly stable proteins and their complexes, the ability to actively transport and concentrate inorganic carbon and other nutrients, to serve as gene donors, microbial cell factories, and sources of bioactive metabolites. A thorough investigation of the recent progress in thermophilic cyanobacteria reveals a significant increase in the number of newly isolated and delineated organisms and wide application of thermophilic light-harvesting components in biohybrid devices. Yet despite these achievements, there are still deficiencies at the high-end of the biotechnological learning curve, notably in genetic engineering and gene editing. Thermostable proteins could be more widely employed, and an extensive pool of newly available genetic data could be better utilised. In this manuscript, we attempt to showcase the most important recent advances in thermophilic cyanobacterial biotechnology and provide an overview of the future direction of the field and challenges that need to be overcome before thermophilic cyanobacterial biotechnology can bridge the gap with highly advanced biotechnology of their mesophilic counterparts. Key points • Increased interest in all aspects of thermophilic cyanobacteria in recent years • Light harvesting components remain the most biotechnologically relevant • Lack of reliable molecular biology tools hinders further development of the chassis Graphical Abstract
