    Abstract: This book describes emerging and established industrial processes of biomining technologies used for the recovery of metals of economic interest from, e.g. mineral ores, mining and electronic wastes using microbiological technologies. Multiple chapters focus on engineering design and operation of biomining systems. Several industrial case studies from China, Chile, Peru, Russia/Kazakhstan and Finland are included, which emphasises the practical approach of the book. The reader not only learns more about the biology, diversity and ecology of microorganisms involved in biomining processes, but also about microbial biomolecular and cultivation tools used in the biomining industry. Special emphasis is put on emerging biotechnologies enabling the use of biomining for recycling metals from e-wastes, waste streams and process waters. Finally, the future impacts and direction of biomining towards sustainability in a metal-demanding world are also highlighted. The book is aimed at an interdisciplinary audience involving operators and researchers working across disciplines including geology, chemical engineering, microbiology and molecular biology. This is reflected by the content of this book, as well as by its authors, who are all leading practitioners and authorities in their fields.

    Abstract: This textbook addresses global and local environmental problems and the involvement of microorganisms in their development and remediation. In particular, methodological aspects, some of them molecular genetic, for the study of microbial communities are considered. Overall, the prominent role of microorganisms in various material cycles is presented. In addition to biochemical principles for the degradation of environmental pollutants, the use of microorganisms in environmental biotechnological processes for the purification of air, water or soil as well as in environmentally friendly production processes is discussed. The book is intended for biologists with an interest in environmental microbiological issues, but also for students of process or environmental engineering, geoecology or geology, as well as students of other environmental science disciplines. For the 3rd edition, the authors have completely revised, corrected, updated and supplemented the book. The authors Professor Dr. Walter Reineke was Professor of Microbiology at the University of Wuppertal since 1982, where he was involved in teaching both the Food Chemistry and Chemistry courses. He has been retired since August 2013. Professor Dr. Michael Schlömann was appointed Endowed Professor of Environmental Microbiology of the Deutsche Bundesstiftung Umwelt at the Technische Universität Bergakademie Freiberg in 1998 and has been Deputy Director of the University's Interdisciplinary Ecological Centre since 1999. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.

    Notes: Abstract Dienelactone hydrolases (EC 3.1.1.45) have been shown to play an indispensable role in the degradation of chloroaromatic compounds via ortho-cleavage of chlorocatechols. We report on the purification of dienelactone hydrolase of the chlorophenol-utilizing strain Rhodococcus erythropolis 1CP to apparent homogeneity. Dienelactone hydrolase differed fron the corresponding enzymes of other chloroaromatic compound-catabolizing strains in being restricted to substrates with a cis-dienelactone structure. From the cis-dienelactone-hydrolyzing enzyme of a 4-fluorobenzoate-utilizing Burkholderia (Pseudomonas) cepacia strain, it differed considerably in properties such as pH optimum of activity, inhibition by p-chloromercuribenzoate, and amino acid composition. Thus, there is not necessarily a close relationship between substrate specificity and other properties of dienelactone hydrolases.

    Notes: Abstract 2,4-Dichlorophenoxyacetate (2,4-D) in Alcaligenes eutrophus JMP134 (pJP4) is degraded via 2-chloromaleylacetate as an intermediate. The latter compound was found to be reduced by NADH in a maleylacetate reductase catalyzed reaction. Maleylacetate and chloride were formed as products of 2-chloromaleylacetate reduction, the former being funnelled into the 3-oxoadipate pathway by a second reductive step. There was no indication for an involvement of a pJP4-encoded enzyme in either the reduction or the dechlorination reaction.

    Notes: Open pit mining characterizes the area of Lusatia (Germany), which corresponds todramatic changes of the natural ecosystem. Landscapes with huge waste heaps and acid minelakes are created by former mining activities.The studied waste heap is about 70 years old and is situated between two lakes (Restsee107 and Restsee 108) formed ten years later. Samples taken by drilling drills showed hints ofactive sulfate reduction activities within the heap and the ground water. Black precipitationswere visible on the sediment cores and an intensive H2S odor was noticed.Investigations of the hydrochemistry of the ground water within the heap were started withthe drilling of twelve wells along two parallel lines (I, II). Various analytical parameters weremeasured (see Storch et al. IBS 2007, short lecture topic environmental problems).The bacterial communities of two wells are investigated by molecular methods. The watersamples differ in pH (MPL1: 2.4 and MPL11: 4.4) and were therefore chosen to investigateinto more detail. Creating a 16S rDNA library, the microbial diversity in the water wascharacterized. The 200 clones of sample MPL11 were highly diverse: a restriction analysisusing the enzyme RsaI revealed 120 different restriction types. Numbers of sequences wererelated to sulfate reducing bacteria and to uncultivated bacteria from acidic environmentalsites. The obtained sequences will be used to study the remaining wells by T-RFLP and todiscuss these results in respect to sulfate reduction under acidic conditions

    Notes: In the Lusatia area a pilot plant for the treatment of acidic mine waters by microbial ironoxidation and a concomitant iron hydroxysulfate precipitation is operated.Molecular based studies of acidic waters from this iron hydroxysulfate producing pilot plantrevealed the presence of 16S rRNA gene sequences from undescribed iron-oxidizing bacteria. Mostof these were related to autotrophic Betaproteobacteria (see Heinzel et al. IBS 2007, poster number98).For cultivating different iron-oxidizing bacteria water samples from this pilot plant were directlyplated on various solid media. Double-layer plates were used, with a heterotrophic Acidiphiliumstrainin the underlayer, because of the high sensitivity of autotrophic bacteria towards organicsubstances. The media contained different iron-substrates with and without organic carbon sources.Colonies appeared at the latest after three weeks and they were encrusted with ferric iron. Thephylogeny of the isolated strains was determined and the physiological requirements, liketemperature, pH optima, preferred carbon source and iron concentrations, were analyzed. Manyisolates which were related to Acidithiobacillus ferrooxidans strains could be cultivated, as well asan isolate related to the genus Thiomonas and one isolate related to a Ferribacter polymyxa species.The Thiomonas-like isolate showed best growth in media containing tryptone soya broth, sodiumthiosulfate and ferrous sulfate at pH 2.5 and 30°C. The other Betaproteobacterium grew on ferroussulfate medium at pH 2.5 between 16 and 37°C. In liquid culture experiments the cells of bothisolates were attached to the iron minerals built in the medium. These physiological characteristicsof the isolates helped to vary parameters in the pilot plant to optimize the process of iron oxidationand improved waste water remediation

    Notes: The microbial community of a pilot plant for the production of iron hydroxysulfates bybiological oxidation of ferrous iron was studied using molecular techniques. The 16S rRNA genelibraries were dominated by one sequence type, which can be classified phylogenetically to theclass of Betaproteobacteria. These bacteria have no close cultivated relatives and were also provedas the dominating species in other mine waters.The microbial community was observed over a period of 18 months using TRFLP to investigatethe influence of different process parameters on the composition of the microbial diversity. Thesestudies verified the dominance of the Betaproteobacteria in the pilot plant

    Notes: Abstract The catechol catabolic genes catABC from Rhodococcus opacus 1CP have previously been characterized by sequence analysis of the insert cloned on plasmid pRER1. Now, a 5.1-kb DNA fragment which overlaps with the insert of pRER1 was cloned, yielding pRER2, and subjected to sequencing. Besides three other open reading frames, a gene was detected ca 200 bp upstream of the catechol 1,2-dioxygenase gene catA, which is obviously transcribed divergently from catABC. The protein which can be deduced from this gene, CatR, resembles members of the PobR subfamily of IclR-type regulatory proteins. This finding was unexpected, as all catechol and chlorocatechol gene clusters known thus far from proteobacteria are under control of LysR-type regulators. It was not possible to inactivate catR by homologous recombination. However, heterologously expressed CatR in vitro bound specifically to the intergenic region between catR and catA thereby providing a first indication for a possible involvement of CatR in the regulation of catechol catabolism.
