Genome Sequence and Description of Haloferax Massiliense Sp. Nov., a New Halophilic Archaeon Isolated from the Human Gut
Extremophiles (2018) 22:485–498 https://doi.org/10.1007/s00792-018-1011-1 ORIGINAL PAPER Genome sequence and description of Haloferax massiliense sp. nov., a new halophilic archaeon isolated from the human gut Saber Khelaifa1 · Aurelia Caputo1 · Claudia Andrieu1 · Frederique Cadoret1 · Nicholas Armstrong1 · Caroline Michelle1 · Jean‑Christophe Lagier1 · Felix Djossou2 · Pierre‑Edouard Fournier1 · Didier Raoult1,3 Received: 14 November 2017 / Accepted: 5 February 2018 / Published online: 12 February 2018 © The Author(s) 2018. This article is an open access publication Abstract By applying the culturomics concept and using culture conditions containing a high salt concentration, we herein isolated the frst known halophilic archaeon colonizing the human gut. Here we described its phenotypic and biochemical characteriza- tion as well as its genome annotation. Strain Arc-HrT (= CSUR P0974 = CECT 9307) was mesophile and grew optimally at 37 °C and pH 7. Strain Arc-HrT was also extremely halophilic with an optimal growth observed at 15% NaCl. It showed gram-negative cocci, was strictly aerobic, non-motile and non-spore-forming, and exhibited catalase and oxidase activities. The 4,015,175 bp long genome exhibits a G + C% content of 65.36% and contains 3911 protein-coding and 64 predicted RNA genes. PCR-amplifed 16S rRNA gene of strain Arc-HrT yielded a 99.2% sequence similarity with Haloferax prahovense, the phylogenetically closest validly published species in the Haloferax genus. The DDH was of 50.70 ± 5.2% with H. prahovense, 53.70 ± 2.69% with H. volcanii, 50.90 ± 2.64% with H. alexandrinus, 52.90 ± 2.67% with H. -

INVESTIGATION OF 2-OXOACID OXIDOREDUCTASES IN METHANOCOCCUS MARIPALUDIS AND LARGE-SCALE GROWTH OF M. MARIPALUDIS by BRIAN W. WATERS (Under the direction of Dr. William B. Whitman) ABSTRACT With the emergence of Methanococcus maripaludis as a genetic model for methanogens, it becomes imperative to devise inexpensive yet effective ways to grow large numbers of cells for protein studies. Chapter 2 details methods that were used to cut costs of growing M. maripaludis in large scale. Also, large scale growth under different conditions was explored in order to find the conditions that yield the most cells. Chapter 3 details the phylogenetic analysis of 2-oxoacid oxidoreductase (OR) homologs from M. maripaludis. ORs are enzymes that catalyze the oxidative decarboxylation of 2-oxoacids to their acyl-CoA derivatives in many prokaryotes. Also in chapter 3, a specific OR homolog in M. maripaludis, an indolepyruvate oxidoreductase (IOR), was mutagenized, and the mutant was characterized. PCR and Southern hybridization analysis showed gene replacement. A no-growth phenotype on media containing aromatic amino acid derivatives was found.

The last step is catalyzed by methanogens which produce primarily methane, carbon dioxide, and water as products of metabolism. Anaerobic digestion occurs naturally in a variety of water-saturated sediments, but is also used to treat waste in constructed reactors. There are a number of advantages to treating waste with anaerobic digestion, but perhaps the greatest is that waste treatment can be coupled to energy generation by the production of a methane-rich biogas. Despite the advantages, anaerobic digestion is severely under-utilized in waste treatment mainly due to the belief that anaerobic digesters are less stable than aerobic treatment processes. Anaerobic digesters are typically operated under warm temperatures and circumneutral pH, with operation outside of these conditions leading to instability and potential reactor failure. -

The Role of Stress Proteins in Haloarchaea and Their Adaptive Response to Environmental Shifts
biomolecules Review The Role of Stress Proteins in Haloarchaea and Their Adaptive Response to Environmental Shifts Laura Matarredona ,Mónica Camacho, Basilio Zafrilla , María-José Bonete and Julia Esclapez * Agrochemistry and Biochemistry Department, Biochemistry and Molecular Biology Area, Faculty of Science, University of Alicante, Ap 99, 03080 Alicante, Spain; [email protected] (L.M.); [email protected] (M.C.); [email protected] (B.Z.); [email protected] (M.-J.B.) * Correspondence: [email protected]; Tel.: +34-965-903-880 Received: 31 July 2020; Accepted: 24 September 2020; Published: 29 September 2020 Abstract: Over the years, in order to survive in their natural environment, microbial communities have acquired adaptations to nonoptimal growth conditions. These shifts are usually related to stress conditions such as low/high solar radiation, extreme temperatures, oxidative stress, pH variations, changes in salinity, or a high concentration of heavy metals. In addition, climate change is resulting in these stress conditions becoming more significant due to the frequency and intensity of extreme weather events. The most relevant damaging effect of these stressors is protein denaturation. To cope with this effect, organisms have developed different mechanisms, wherein the stress genes play an important role in deciding which of them survive. Each organism has different responses that involve the activation of many genes and molecules as well as downregulation of other genes and pathways. Focused on salinity stress, the archaeal domain encompasses the most significant extremophiles living in high-salinity environments. To have the capacity to withstand this high salinity without losing protein structure and function, the microorganisms have distinct adaptations. -

Aristotle (384-322 BC) He was a Greek philosopher and scientist born in the city of Stagira, Chalkidice of classical Greece. His father died when Aristotle was a child. At eighteen, he joined Plato's Academy in Athens and remained there until the age of thirty seven (c.347 BC). His writings cover many subjects including physics, biology, zoology, metaphysics, poetry, politics and government. Shortly after Plato died, Aristotle left Athens and, at the request of Philip of Macedon, tutored Alexander the Great. Aristotle was the first genuine scientist in history and every scientist is in his debt.He is regarded as father of biology and zoology.
