2003 Summer Mono Lake Newsletter
hose of you who have diligently read each issue of the Mono Lake Newsletter this year may start to notice that there is something of a pattern forming. It’s the TMono Lake Committee’s 25th Anniversary and we thought, “What better way to celebrate with all the members and friends than through the newsletter?” The first issue highlighted the fact that while the Mono Lake story may appear to be a well-planned one, in 1979 no one ever would have guessed things would have Mono Lake Office turned out with a healthy lake in the end. Only with the amazing efforts of many Information Center and Bookstore people could this sometimes-calculated, sometimes-serendipitous story have turned Highway 395 at Third Street out so well. The second issue focused on the Committee’s long-standing connection Post Office Box 29 Lee Vining, California 93541 with science, and how scientific findings motivated a small group of dedicated (760) 647-6595 students who just couldn’t watch Mono dry up. This, the third issue, focuses on the [email protected] political history that took science-based knowledge to the public, to courtrooms, and www.monolake.org to anyone who would listen, and turned it into the protection that the lake has today. www.monobasinresearch.org The final issue for the year will focus on education, the third pillar of the Los Angeles Office Committee’s three-word mantra: Protection, Restoration, Education. With these 322 Culver Blvd. Playa Del Rey, California 90293 issues firmly under our belts we head off into the next 25 years. -

Singh Department of Biosciences Saurashtra University, Rajkot- 360 005 E mail: [email protected] CONTENTS Introduction Extreme Environments and their Microbial Life Thermophiles Halophiles and Haloalkaliphiles Uncultivable Microbes Adaptation to Extremity Halophiles And Haloalakliphiles Haloalakliphilic Bacteria & Archaebacteria Thermophiles and Hyperthermophiles Applications and New Horizons Keywords Extremophiles; Extreme habitats; Thermophiles; Hyperthermophiles; Halophiles; Haloalkaliphiles; Macromolecular stability;, Archaebacteria; Dead Seas; Salt lakes; Adaptation strategies. Introduction Microbes play key roles in the life of human being since the time immemorial. We have been exploiting them much before the knowledge and realization of their existence in the universe. However, the microbes played havoc time to time in the form of infectious diseases and other forms of their detrimental activities. Therefore, they are referred as both friend and foe to the society and human being. Systematic applications of microbes date back to the days of Louis Pasteur, when he established the relationship between chemical transformations and the existence of microbes. The active involvement of microbes in daily life is due to their versatility, diversity and fast growth. They affect almost every spheres of our life ranging from agriculture to industry and from environment to health. In view of their role in human society, the microbes have been the center of attraction for researchers and during the last century several turning points and milestones were established. This led to the better understanding of the organisms and their impact on human society. Considering the contemporary developments towards modern biology, the elucidation of the DNA structure has been a major turning point. -
Spirochaetes Dominate the Microbial Community Associated with the Red
www.nature.com/scientificreports OPEN Spirochaetes dominate the microbial community associated with the red coral Corallium rubrum Received: 10 February 2016 Accepted: 18 May 2016 on a broad geographic scale Published: 06 June 2016 Jeroen A. J. M. van de Water1,*, Rémy Melkonian1,*, Howard Junca2, Christian R. Voolstra3, Stéphanie Reynaud1, Denis Allemand1 & Christine Ferrier-Pagès1 Mass mortality events in populations of the iconic red coral Corallium rubrum have been related to seawater temperature anomalies that may have triggered microbial disease development. However, very little is known about the bacterial community associated with the red coral. We therefore aimed to provide insight into this species’ bacterial assemblages using Illumina MiSeq sequencing of 16S rRNA gene amplicons generated from samples collected at five locations distributed across the western Mediterranean Sea. Twelve bacterial species were found to be consistently associated with the red coral, forming a core microbiome that accounted for 94.6% of the overall bacterial community. This core microbiome was particularly dominated by bacteria of the orders Spirochaetales and Oceanospirillales, in particular the ME2 family. Bacteria belonging to these orders have been implicated in nutrient cycling, including nitrogen, carbon and sulfur. While Oceanospirillales are common symbionts of marine invertebrates, our results identify members of the Spirochaetales as other important dominant symbiotic bacterial associates within Anthozoans. The economically valuable red coral Corallium rubrum is an important habitat-forming species that provides structural complexity to benthic communities in the Mediterranean Sea. While commercial over-exploitation for use in jewellery is one of the main threats, ocean acidification1 and elevated seawater temperatures2 may also pose a risk to C. -

The rod-shaped cells were motile, Gram-positive, formed spores and were 0?4–0?562?5–5?0 mm in size. Growth occurred within the pH range 6?7–10?0 and was optimal at pH 8?5. The temperature range for growth was 10–45 6C, with optimal growth at 35 6C. NaCl was required for growth. Growth occurred at 0?5–9?0 % (w/v) NaCl and was optimal at 1–2 % (w/v). The novel isolate was a catalase-negative chemo-organoheterotroph that fermented sugars, proteolysis products, some organic and amino acids, glycerol, D-cellobiose and cellulose. -
ANAEROBIC HALOPHILIC ALKALITHERMOPHILES: DIVERSITY and PHYSIOLOGICAL ADAPTATIONS to MULTIPLE EXTREME CONDITIONS by NOHA MOSTAFA
ANAEROBIC HALOPHILIC ALKALITHERMOPHILES: DIVERSITY AND PHYSIOLOGICAL ADAPTATIONS TO MULTIPLE EXTREME CONDITIONS by NOHA MOSTAFA MESBAH (Under the Direction of Juergen Wiegel) ABSTRACT Halophilic alkalithermophiles are poly-extremophiles adapted to grow at high salt concentrations, alkaline pH values and temperatures greater than 50ºC. Halophilic alkalithermophiles are of interest from physiological perspectives as they combine unique adaptive mechanisms and cellular features that enable them to grow under extreme conditions. The alkaline, hypersaline lakes of the Wadi An Natrun, Egypt were chosen as sources for isolation of novel halophilic alkalithermophiles. These lakes are characterized by saturating concentrations of NaCl (5.6 M), alkaline pH (8.5-11) and temperatures of 50ºC due to intense solar irradiation. The prokaryotic communities of three large lakes of the Wadi An Natrun were assessed using 16S rRNA clone libraries. The Wadi An Natrun lakes are dominated by three phylogenetic groups of Bacteria (Firmicutes, Bacteroidetes, α- and γ-proteobacteria) and two groups of Archaea (Halobacteriales and Methanosarcinales). Extensive diversity exists within each phylogenetic group; half of the clones analyzed did not have close cultured or uncultured relatives. Three novel halophilic alkalithermophiles were isolated from the Wadi An Natrun. A novel order, Natranaerobiales, was proposed to encompass these novel isolates. Natranaerobius thermophilus was chosen as a model for more detailed physiological studies. Analysis of the bioenergetic characteristics of N.thermophilus revealed the absence of cytoplasmic pH homeostasis. Rather, N.thermophilus has the novel feature of maintaining the cytoplasmic pH at a constant 1 unit below that of the extracellular pH, the cytoplasmic pH continuously changed with the extracellular pH. -
