Industrial biotechnology aims to produce chemicals, materials and biofuels to ease the challenges of shortage on petroleum. However, due to the disadvantages of bioprocesses including energy consuming sterilization, high fresh water consumption, discontinuous fermentation to avoid microbial contamination, highly expensive stainless steel fermentation facilities and competing substrates for.
Global warming and the limitations of using fossil fuels are a main concern of all societies, and thus, the development of alternative fuel sources is crucial to improving the current global energy situation. Biofuels are known as the best alternatives of unrenewable fuels and justify increasing extensive research to develop new and less expensive methods for their production.
Extremophiles include a diverse group with ability to survive in highly saline conditions, the halophiles. Halophiles are characterized in major life domains including Archaea as well as Bacteria. Archaea represents halophiles with heterotrophic, chemotrophic aerobes and anaerobes. A large number of members from these domains are found growing in diverse habitats including both thalassohaline.

Abstract: Polyhydroxyalkanoates (PHA) are biodegradable polyesters, which are produced by various bacteria including numerous halophiles. Employment of halophilic strain for PHA production brings numerous benefits such as robustness of the process against contamination by ubiquitous mesophiles or possibility to isolate polymer from bacterial biomass via hypotonic lysis.
Research paper examples are of great value for students who want to complete their assignments timely and efficiently. If you are a student in the university, your first stop in the quest for research paper examples will be the campus library where you can get to view the research sample papers of lecturers and other professionals in diverse fields plus those of fellow students who preceded.
Isolation and characterization of bacterial host strains. Sediment sample plus the overlying water were collected (March, 2013) into sterile jars, capped on site and preserved in cooled boxes for transportation to the molecular laboratory in Jomo Kenyatta University of Agriculture and Technology (JKUAT).
Most halophiles use only use one of these two approaches, although a few halophiles can use both. Taxonomy and phylogeny of halophiles The first halophilic fermentative bacterial species, Halanaerobium praevalens was isolated from the sediments of the Great Salt Lake (Utah) and characterized in 1983 8 and placed firmly in the family Bacteroidaceae as a genus with uncertain affiliation 8.
Raman spectroscopy plays a major role in robust detection of biomolecules and mineral signatures in halophile research. An overview of Raman spectroscopic investigations in halophile research of the last decade is given here to show advantages of the approach, progress made as well as limits of the technique. Raman spectroscopy is an excellent tool to monitor and identify microbial pigments.
However, reports of multidisciplinary research are uncommon. In this paper, we report an interdisciplinary three-day field campaign conducted in the framework of the Coordination Action for Research Activities on Life in Extreme Environments (CAREX) FP7EU program, with participation of experts in the fields of life and earth sciences.
Posts about Halophiles written by Jonathan Eisen. After posting A tale of salt and gender: participation of women in halophile research I sent the post to Bonnie Baxter, one of the authors of the article I discussed and I asked if she would be interested in writing a guest post about the “Story Behind the Paper” (for which I have a whole series).
This book highlights current genetics and genomics research on halophilic Archaea and Bacteria and their viruses to provide a timely overview. Topics include: ecology and evolution of Haloquadratum walsbyi; microdiversity of Salinibacter ruber; horizontal gene transfer in halobacteria; comparative genomics of haloarchaeal viruses; and much more.

Bacterial and archaeal aerobic communities were recovered from sediments from the shallow El-Djerid salt lake in Tunisia, and their salinity gradient distribution was established. Six samples for physicochemical and microbiological analyses were obtained from 6 saline sites in the lake for physico-chemical and microbiological analyses. All samples studied were considered hypersaline with NaCl.
Research on halophiles has mainly focused on the specific adaptations and molecular mechanisms that enable them to maintain their osmotic balance under salt-stress (7,8,9). A great deal of interest has also been channeled towards the investigation of their diversity and phylogenetic relationships as the highest majority of them constitute ancient evolutionary lineages ( 10, 11 ).Journal of Biological Research-Thessaloniki benefits from its association with Aristotle University of Thessaloniki (AUTH), which founded the journal in 2004 and continues to foster its success. AUTH is the largest university in Greece, comprising seven faculties and a total of 42 Schools. AUTH is widely recognised as a vibrant centre of learning and it draws its inspiration from a long.A dichotomous key that distinguishes the five classes of the gram- negative Proteobacteria.
