2 Table of contents Industrial use of archaea Integrated, innovative complex for growth of archae Opportunities of application and perspectives

3 Archaea Archaea are the smallest independently living single-celled organisms on earth Typical cells range in size from 0.5 to1.0 µm in diameter DNA lies free in the cell cytoplasm A cell membrane comprised of phospholipids surrounds the cell. The cell wall is usually made up of protein and carbohydrate and lipids. Most of the time they undergo asexual reproduction, mostly by dividing in half – some cells divide every 12–20 minutes, others take a lot longer. All organisms require carbon, which provides building blocks for cell materials Archaebacteria are also known as "extremophiles," thanks to their ability to survive in extreme environments such as very hot and very cold climates.

4 Archaea Archaea were originally thought to exist only in harsh environments Were often described as ‚extremophiles’ They are widely distributed and are found alongside bacteria in many environments including soil and water. The best described groups of Archaea are the methanogens that produce methane, and the extremophiles that grow under high salt or extreme temperatures. Pyrodictum, for example, has an optimal growth temperature of 105°C. Colored transmission electron micrograph of the archaea Methanospirillum hungatii undergoing cell division

5 Prokaryotic Cells First cell type on earth Cell type of Bacteria and Archaea No membrane bound nucleus Nucleoid = region of DNA concentration Organelles not bound by membranes

7 Prokaryotic traits: They are about 1 micrometer (μm) in diameter, the size of typical procaryotes. They lack membrane-bound organelles. They have nuclear bodies (nucleoids) rather than true, menbranee bound nuclei. Their ribosomes are 70 S, the size of those found in typical prokaryotes. The archaebacteria have the following unique combination of traits : Eukaryotic traits: Their cell walls completely lack peptidoglycan. Their protein synthesis machinery is sensitive to inhibitors that typically affect only eukaryotes and is resistant to many inhibitors that affect prokaryotes. Some of their proteins, pigments, and biochemical processes closely resemble those found in eukaryotic cells.

8 Archaebacteria include three groups : 1.The methanogens, strict anaerobes that produce methane (CH 4 ) from carbon dioxide and hydrogen. 2.Extreme halophiles, which require high concentrations of salt for survival. 3.Thermoacidophiles, which normally grow in hot, acidic environments.

9 Enzymes and proteins from organisms that grow near and above 100 °C Hyperthermophile group includes some methanogenic and sulfate- reducing species Only a few species are saccharolytic. Most of the hyperthermophiles absolutely depend on the reduction of elemental sulfur (S 0 ) to H 2 S for significant growth, The fermentative pathways appear to depend upon enzymes that contain tungsten

10 Extremophiles as a source of novel enzymes for industrial application Extremophilic microorganisms are adapted to survive in ecological niches:  high temperatures,  extremes of pH,  high salt concentrations  high pressure. These microorganisms produce unique biocatalysts which operateunder extreme conditions Selected extracellular-polymer-degrading enzymes and other enzymes could be used in food, chemical and pharmaceutical industries and in environmental biotechnology. (amylases, pullulanases, cyclodextrin glycosyltransferases, cellulases, xylanases, chitinases, proteinases, esterases, glucose isomerases, alcohol dehydrogenases and DNA-modifying enzymes ) A scanning electron micrograph of a ten-million-year-old Archaea.

11 Biotechnological applications of archaeal biomasses Biological methanogenesis is applied to the anaerobic treatment of o sewage sludge, o agricultural, municipal and industrial wastes Methanogens are a group of microorganisms that obtain energy for growth from the reaction leading to methane production. Many bioreactor configurations have been exploited to increase the efficiency of anaerobic digestion, such as o the rotating biological contactor, o the anaerobic baffle reactor o the upflow anaerobic sludge blanket reactor, o several large-scale plants are in operation

12 Archaeal enzymes of biotechnological interest Natural and modified archaeal enzymes present huge possibilities for industrial applications Many archaeal enzymes involved in carbohydrate metabolism - special interest to the industrial biotechnology sector. The starch processing industry can profit from the exploitation of thermostable enzymes. Another promising application of hyperthermophilic archaeal enzymes is in trehalose production. Several other polymer-degrading enzymes isolated from archaea could play important roles in the chemical, pharmaceutical, paper, pulp or waste treatment industries. (xylanases and cellulases) Some archaeal metabolites have potential industrial applications. (proteins, osmotically active substances, exopolysaccharides and special lipids ) Archaeal lipids have been proposed as monomers for bioelectronics
