Microbial leaching process is considered as an economical and technically viable clear technology for processing low grade manganese ores. Genetically engineered strains of Bacillus sp. produced better resilts (upto 80% enhancement) in 45 days. When compared with the control, metabolites extracted from Pseudomonas sp. gave 40% enhanced bioleaching and Bacillus sp. gave 60% enhancement in 30 days. A simple software package for easy manipulation of metabolic pathways is also being developed. [AUthors' abstract].

Oxygenic photosynthesis fundamentally transformed our planet by releasing molecular oxygen and altering major biogeochemical cycles, and this exceptional metabolism relies on a redox-active cubane cluster of four manganese atoms. Not only is manganese essential for producing oxygen, but manganese is also only oxidized by oxygen and oxygen-derived species. Thus the history of manganese oxidation provides a valuable perspective on our planet's environmental past, the ancient availability of oxygen, and the evolution of oxygenic photosynthesis. Broadly, the general trends of the geologic record of manganese deposition is a chronicle of ancient manganese oxidation: manganese is introduced into the fluid Earth as Mn(II) and it will remain only a trace component in sedimentary rocks until it is oxidized, forming Mn(III,IV) insoluble precipitates that are concentrated in the rock record. Because these manganese oxides are highly favorable electron acceptors, they often undergo reduction in sediments through anaerobic respiration and abiotic reaction pathways. The following dissertation presents five chapters investigating manganese cycling both by examining ancient examples of manganese enrichments in the geologic record and exploring the mineralogical products of various pathways of manganese oxide reduction that may occur in sediments. The first chapter explores the mineralogical record of manganese and reports abundant manganese reduction recorded in six representative manganese-enriched sedimentary sequences. This is followed by a second chapter that further analyzes the earliest significant manganese deposit 2.4 billon years ago, and determines that it predated the origin of oxygenic photosynthesis and thus is supporting evidence for manganese-oxidizing photosynthesis as an evolutionary precursor prior to oxygenic photosynthesis. The lack of oxygen during this early manganese deposition was partially established using oxygen-sensitive detrital grains, and so a third chapter delves into what these grains mean for oxygen constraints using a mathematical model. The fourth chapter returns to processes affecting manganese post-deposition, and explores the relationships between manganese mineral products and (bio)geochemical reduction processes to understand how various manganese minerals can reveal ancient environmental conditions and biological metabolisms. Finally, a fifth chapter considers whether manganese can be mobilized and enriched in sedimentary rocks and determines that manganese was concentrated secondarily in a 2.5 billion-year-old example from South Africa. Overall, this thesis demonstrates how microbial processes, namely photosynthesis and metal oxide-reducing metabolisms, are linked to and recorded in the rich complexity of the manganese mineralogical record.

The metabolic pathway of oxygenic photosynthesis is fueled by sunlight and the oxidation of water; oxygen is produced as a waste product. Before the rise of oxygenic phototrophs 2.3 billion years ago, microbes utilized anoxygenic photosynthesis to form organic carbon compounds using electron donors such as iron [Fe(II)] and reduced sulfur compounds. Anoxygenic phototrophs can be found in modern environments like meromictic lakes. We studied enrichment cultures of microorganisms driven by anoxygenic photosynthesis to determine whether and how they use another possible electron donor, manganese [Mn(II)]. Cultures reduced with sulfide [H2S] and enriched with Mn(II) as a potential electron donor oxidized Mn(II) and formed various manganese oxide minerals in the presence of light. To further characterize these anaerobic microbial communities and the role of manganese, we grew the cultures on different concentrations of Mn(II) and H2S and isolated individual microbes. We characterized the composition of the microbial communities by extracting copies of a specific gene, 16S rRNA, which is highly conserved and a standard species-identifying marker. Communities grew only in the presence of light and obligately anaerobic green sulfur bacteria from the phylum Chlorobi were the only phototrophic organisms. From these communities, we identified several taxa using 16S rRNA gene and whole genome sequencing; most notably, a taxon belonging to Chlorobi identified as Chlorobium limicola and a taxon belonging to Desulfomicrobium identified as Desulfomicrobium baculatum. We found a robust microbial community capable of oxidizing Mn(II) in the absence of molecular oxygen. These communities are driven by anoxygenic photosynthesis and dependent on the concentration of sulfur sources, like sulfide. Optimal conditions for anaerobic oxidation of Mn(II) suggest this process occurs in source environment.

This book provides a timely review of strategies for coping with polluted ecosystems by employing bacteria, fungi and algae. It presents the vast variety of microbial technologies currently applied in the bioremediation of a variety of anthropogenic toxic chemicals, mining and industrial wastes and other pollutants. Topics covered include: microbe-mineral interactions, biosensors in environmental monitoring, iron-mineral transformation, microbial biosurfactants, bioconversion of cotton gin waste to bioethanol, anaerobe bioleaching and sulfide oxidation. Further chapters discuss the effects of pollution on microbial diversity, as well as the role of microbes in the bioremediation of abandoned mining areas, industrial and horticultural wastes, wastewater and sites polluted with hydrocarbons, heavy metals, manganese and uranium.
