“…BCBT21 and Brevibacillus borstelensis to degrade plastic and polyethylene, respectively (Hadad et al 2005;Dang et al 2018). The construction of bacterial consortium by adding thermophilic bacteria are also possibly acknowledged in the future (Sar et al 2013). In addition, metagenomic approach can be taken to address other bioprospective enzymes of explored thermophilic bacteria.…”

Abstract. Lischer K, Putra ABRD, Guslianto BW, Avilla F, Sitorus SG, Nugraha Y, Sarmoko. 2020. Short Communication: The emergence and rise of indigenous thermophilic bacteria exploration from hot springs in Indonesia. Biodiversitas 21: 5474-5481. Indonesia is an archipelagic country located in the pacific ring of fire, and is estimated to cause numerous hot springs spread across the country. In addition, small living microbes have been explored in these locations since 1985. These microbes possess the ability to survive in areas with high temperature (more than 40oC-90oC), and are therefore termed thermophiles. Hence, massive explorations have been conducted on Java island and other unexplored areas at Sumatra to Papua in New Guinea islands. Moreover, a total of 71 hot springs characterized by the presence of thermophilic bacteria have been explored in Indonesia. These investigations ensue with various approaches, including through conventional and microbiological, 16S rRNA, as well as whole-genome sequencing methods. In addition to species exploration, the application of thermophiles has become a topic of interest from 1999, especially based on thermostable enzymes with the capacity to maintain activity at high-temperature conditions. These include amylase, protease, lipase, xylanase, esterase, and cellulase as the most common isolated form, which indicates the existence of significant extractable potentials. Hence, there is a need for further research in terms of both exploration and application purposes.

“…Sometimes the same microorganism owns more metal resistance mechanisms; for example, Escherichia coli possesses either a copper active transport system (CopA) and another system based on multicopper oxidases (CueO) and CusCFBA transport system for periplasmic copper detoxification [ 23 , 44 ]. These resistance mechanisms are often activated as stress response [ 45 , 46 ]; understanding their underpinning molecular basis is crucial for application in the environmental monitoring of metal contamination (biosensing) and/or to set up bioremediation processes [ 14 , 47 , 48 ].…”

“…In this context, investigation on the biology, ecology, and physiology of microorganisms is a necessary prerequisite to set up white and green biotechnologies [ 9 ] in the field of industrial processes, energy generation [ 10 ], prevention of environmental pollution by detection and/or removal of contaminants [ 11 ], and production of biopolymers from renewable resources [ 12 , 13 ]. For example, thermophilic microorganisms can find applications to reduce pollution in industrial wastewaters that are often characterized by higher temperatures and highly dissolved heavy metals [ 14 , 15 ]. Moreover, thermophiles are more advantageous than mesophiles in biorefineries which require high-temperature steps [ 16 ].…”

Extremophiles are microorganisms that populate habitats considered inhospitable from an anthropocentric point of view and are able to tolerate harsh conditions such as high temperatures, extreme pHs, high concentrations of salts, toxic organic substances, and/or heavy metals. These microorganisms have been broadly studied in the last 30 years and represent precious sources of biomolecules and bioprocesses for many biotechnological applications; in this context, scientific efforts have been focused on the employment of extremophilic microbes and their metabolic pathways to develop biomonitoring and bioremediation strategies to face environmental pollution, as well as to improve biorefineries for the conversion of biomasses into various chemical compounds. This review gives an overview on the peculiar metabolic features of certain extremophilic microorganisms, with a main focus on thermophiles, which make them attractive for biotechnological applications in the field of environmental remediation; moreover, it sheds light on updated genetic systems (also those based on the CRISPR-Cas tool), which expand the potentialities of these microorganisms to be genetically manipulated for various biotechnological purposes.

“…Therefore, (hyper)thermophiles offer a suitable solution due to their capabilities to grow at such high-temperature and also resist and metabolize several pollutants from contaminated industrial wastewaters ( Vieille and Zeikus, 1996 ). Previous studies have demonstrated the high potential of (hyper)thermophilic pure cultures and consortia for bioremediation of heavy metal-contaminated surface and groundwaters, including biosorption and immobilization of radionuclides and heavy metals ( Chatterjee et al, 2010 ; Sar et al, 2013 ), removal of heavy metals ( Ilyas et al, 2014 ) and for degradation of persistent organic compounds such as aliphatic and (poly)aromatic hydrocarbons ( Mnif et al, 2014 ; Zhou et al, 2018 ), and synthetic dyes ( Deive et al, 2010 ). Increasing research is conducted into evaluating the applications of thermostable enzymes in waste treatment and remediation ( Kataoka et al, 2014 ; Wang et al, 2015 ; Rigoldi et al, 2018 ).…”

Extremophiles are organisms capable of adjust, survive or thrive in hostile habitats that were previously thought to be adverse or lethal for life. Chile gathers a wide range of extreme environments: salars, geothermal springs, and geysers located at Altiplano and Atacama Desert, salars and cold mountains in Central Chile, and ice fields, cold lakes and fjords, and geothermal sites in Patagonia and Antarctica. The aims of this review are to describe extremophiles that inhabit main extreme biotopes in Chile, and their molecular and physiological capabilities that may be advantageous for bioremediation processes. After briefly describing the main ecological niches of extremophiles along Chilean territory, this review is focused on the microbial diversity and composition of these biotopes microbiomes. Extremophiles have been isolated in diverse zones in Chile that possess extreme conditions such as Altiplano, Atacama Desert, Central Chile, Patagonia, and Antarctica. Interesting extremophiles from Chile with potential biotechnological applications include thermophiles (e.g., Methanofollis tationis from Tatio Geyser), acidophiles (e.g., Acidithiobacillus ferrooxidans, Leptospirillum ferriphilum from Atacama Desert and Central Chile copper ores), halophiles (e.g., Shewanella sp. Asc-3 from Altiplano, Streptomyces sp. HKF-8 from Patagonia), alkaliphiles (Exiguobacterium sp. SH31 from Altiplano), xerotolerant bacteria (S. atacamensis from Atacama Desert), UV- and Gamma-resistant bacteria (Deinococcus peraridilitoris from Atacama Desert) and psychrophiles (e.g., Pseudomonas putida ATH-43 from Antarctica). The molecular and physiological properties of diverse extremophiles from Chile and their application in bioremediation or waste treatments are further discussed. Interestingly, the remarkable adaptative capabilities of extremophiles convert them into an attractive source of catalysts for bioremediation and industrial processes.
