Department of Biochemistry at the University of, Georgia and pioneer in studies of sulfate reducing. bacteria and hydrogenases , During the last thirty years there have been tremendous advances within. all realms of microbiology The most obvious are those resulting from. studies using genetic and molecular biological methods The sequencing of. whole genomes of a number of microorganisms having different physiolo . gic properties has demonstrated their enormous diversity and the fact that. many species have metabolic abilities previously not recognized Sequences. have also con rmed the division of prokaryotes into the domains of. Archaea and bacteria Terms such as hyper or extreme thermopiles ther . mophilic alkaliphiles acidophiles and anaerobic fungi are now used. throughout the microbial community With these discoveries has come a. new realization about the physiological and metabolic properties of. microoganisms This in turn has demonstrated their importance for the. development maintenance and sustenance of all life on Earth Recent esti . mates indicate that the amount of prokaryotic biomass on Earth equals . and perhaps exceeds that of plant biomass The rate of uptake of carbon. by prokaryotic microorganisms has also been calculated to be similar to. that of uptake of carbon by plants It is clear that microorganisms play. extremely important and typically dominant roles in recycling and seques . tering of carbon and many other elements including metals . Many of the advances within microbiology involve anaerobes They have. metabolic pathways only recently elucidated that enable them to use carbon. dioxide or carbon monoxide as the sole carbon source Thus they are able. to grow autotrophically These pathways differ from that of the classical. Calvin Cycle discovered in plants in the mid 1900s in that they lead to the. formation of acetyl CoA rather than phosphoglycerate The new pathways. are prominent in several types of anaerobes including methanogens ace . togens and sulfur reducers It has been postulated that approximately. twenty percent of the annual circulation of carbon on the Earth is by anaer . obic processes That anaerobes carry out autotrophic type carbon dioxide. xation prompted studies of the mechanisms by which they conserve energy. and generate ATP It is now clear that the pathways of autotrophic carbon. dioxide xation involve hydrogen metabolism and that they are coupled to. viii Preface, electron transport and generation of ATP by chemiosmosis Enzymes. catalyzing the metabolism of carbon dioxide hydrogen and other materials. for building cell material and for electron transport are now intensely. studied in anaerobes Almost without exception these enzymes depend on. metals such as iron nickel cobalt molybdenum tungsten and selenium . This pertains also to electron carrying proteins like cytochromes several. types of iron sulfur and avoproteins Much present knowledge of electron. transport and phosphorylation in anaerobic microoganisms has been. obtained from studies of sulfate reducers More recent investigations with. methanogens and acetogens corroborate the ndings obtained with the. sulfate reducers but they also demonstrate the diversity of mechanisms and. pathways involved , This book stresses the importance of anaerobic microorganisms in nature. and relates their wonderful and interesting metabolic properties to the fas . cinating enzymes that are involved The rst two chapters by H Gest and. H G Schlegel respectively review the recycling of elements and the. diversity of energy resources by anaerobes As mentioned above hydrogen. metabolism plays essential roles in many anaerobes and there are several. types of hydrogenase the enzyme responsible for catalyzing the oxidation. and production of this gas Some contain nickel at their catalytic sites in. addition to iron sulfur clusters while others contain only iron sulfur clus . ters They also vary in the types of compounds that they use as electron car . riers The mechanism of activation of hydrogen by enzymes is discussed by. Simon P J Albracht and the activation of a puri ed hydrogenase from. Desulfovibrio vulgaris and its catalytic center by B Hanh Huynh P Tavares . A S Pereira I Moura and J G Moura The biosynthesis of iron sulfur clus . ters which are so prominent in most hydrogenases formate and carbon. monoxide dehydrogenases nitrogenases many other reductases and several. types of electron carrying proteins is explored by J N Agar D R Dean and. M K Johnson R J Maier J Olson and N Mehta write about genes and pro . teins involved in the expression of nickel dependent hydrogenases Genes. and the genetic manipulations of Desulfovibrio are examined by J D Wall. and her research associates In Chapter 8 G Voordouw discusses the func . tion and assembly of electron transport complexes in Desulfovibrio vulgaris . In the next chapter Richard Cammack and his colleagues introduce eukary . otic anaerobes including anaerobic fungi and their energy metabolism They. explore the role of the hydrogenosome which in the eukaryotic anaerobes. replaces the mitochondrion A rather new aspect related to anerobic. microorganisms is the observation that they exhibit some degree of toler . ance toward oxygen They typically lack the known oxygen stress enzymes. superoxide dismutase and catalase but they contain novel iron containing. protein including hemerythrin like proteins desulfoferrodoxin rubrery . thrin new types of rubredoxins and a new enzyme termed superoxide. reductase D M Kurtz Jr discuses in Chapter 10 these proteins and pro . poses that they function in the defense toward oxygen stress in anaerobes. Preface ix, and microaerophiles Over six million tons of methane is produced biolog .
ically each year most of it from acetate by methanogenic anaerobes J G . Ferry describes in Chapter 11 that reactions include the activation of acetate. to acetyl CoA which is cleaved by acetyl CoA synthase The methyl group. is subsequently reduced to methane and the carbonyl group is oxidized to. carbon dioxide The pathway is similar but reverse of that of acetyl CoA. synthesis by acetogens but it involves cofactors unique to the methane . producing Archaea Selenium has been found in several enzymes from. anaerobes including species of clostridia acetogens and methanogens In. Chapter 12 W T Self has summarized properties of selenoenzymes that are. divided into three groups The rst constitutes amino acid reductases that. utilize glycine sarcosine betaine and proline In these and also in the second. group which includes formate dehydrogenases selenium is present as. selenocysteine Selenocysteine is incorporated into the polypeptide chain. via a special seryl tRNA and selenophosphate The third group of sele . noenzymes is selenium molybdenum hydroxylases found in purinolytic. clostridia The nature of the selenium in this group has yet to be determined . Chapters 13 and 14 deal with acetogens which produce anaerobically a tril . lion kilograms of acetate each year by carbon dioxide xation via the acetyl . CoA pathway H L Drake and K K sel highlight the diversity of acetogens. and their ecological roles A Das and L G Ljungdahl discuss evidence that. the acetyl CoA pathway of carbon dioxide xation is coupled with electron. transport and ATP generation In addition they present some data showing. how acetogens can deal with oxydative stress In Chapter 15 D P Kelly dis . cusses the biochemical features common to both anaerobic sulfate reducing. bacteria and aerobic thiosulfate oxidizing thiobacilli His chapter is also a. tribute to Harry Peck The last three chapters are devoted to the reduction. by anaerobic bacteria of metals metalloids and nonessential elements L L . Barton R M Plunkett and B M Thomson in their review point out the geo . chemical importance these reductions which involve both metal cations and. metal anions J Wiegel J Hanel and K Aygen describe the isolation of. recently discovered chemolithoautotrophic thermophilic iron III reducers. from geothermally heated sediments and water samples of hot springs They. propose that these bacteria are ancient and were involved in formation of. iron deposits during the Precambrian era The last chapter is a discussion of. electron ow in ferrous bioconversion by E J Laishley and R D Bryant . They visualize a model for biocorrosion by sulfate reducing bacteria. that involves both iron and nickel iron hydrogenases high molecular. cytochrome and electron transport using sulfate as an acceptor .
