Abstract

In order to convert lignite coals into liquid fuels, gases or chemical feedstock, the macromolecular structure of the coal must be broken down into low molecular weight fractions prior to further modification. Our research focused on this aspect of coal bioprocessing. We isolated, characterized and studied the lignite coal-depolymerizing organisms Streptomyces viridosporus T7A, Pseudomonas sp. DLC-62, unidentified bacterial strain DLC-BB2 and Gram-positive Bacillus megaterium strain DLC-21. In this research we showed that these bacteria are able to solubilize and depolymerize lignite coals using a combination of biological mechanisms including the excretion of coal solublizing basic chemical metabolites and extracellular coal depolymerizing enzymes.

Bioprocessing of lignite coals using reductive microorganisms

Technical Report Crawford, D

Research continued on bioprocessing of lignite. This quarter results are as follows: Pseudomonas strain DLC-62 produces an extracellular enzyme activity which depolymerizes a water soluble lignite coal polymer at acidic pH's. The lignite depolymerase acts in a nonoxidative fashion, presumably hydrolytically. In the present work we find that the enzymes present in active extracellular culture filtrates of DLC-62 are composed almost exclusively of multiple esterases and peroxidases. One of the esterase isoforms was synthesized constitutively, while others were induced, albeit variably, by coal. The two peroxidase isoforms were constitutively expressed. In liquid medium, both activities were maximally expressed approximately 36--48more »« less
Bioprocessing of lignite coals using reductive microorganisms

Technical Report Crawford, D.

Depolymerization of lignite is being investigated. Research objectives include: isolate and characterize microbial strains that carry out chemical transformations of lignite coal that would cause its depolymerization, reduction, and/or liquefaction; characterize desirable reactions by growing selected of the microbial isolates on coal model compounds, and determine if the reactions occur when the microbial strains are growing on coal; and characterize several newly isolated coal-depolymerizing bacteria to determine their mechanisms of coal depolymerization, and utilize the depolymerized coal as a substrate for the isolation of additional strictly anaerobic bacteria that reductively transform the depolymerized coal.

Bioprocessing of lignite coals using reductive microorganisms

Technical Report Crawford, D.

A major goal of this project is to isolate unique microbial strains that catalyze a variety of biochemical transformations of low molecular weight coal substructure model compounds and then to determine if these strains will carry out similar reactions with coal. We have several enrichments underway using suitable model compounds such as pyrogallol (2,3-dihydroxyphenol) and gallic acid (3,4,5-trihydroxybenzoic acid) to isolate organisms that reductively dehydroxylate phenolic hydroxyl groups. We are also using various naphthoquinone and antrhaquinone dyes as substrates in isolation procedures. The most promising results so far are with hydroxynaphthoquinone. The purple non-sulfur bacteria belonging to the genus Rhodobactermore »« less

The solubilization of low-ranked coals by microorganisms

Conference Strandberg, G

Late in 1984, our Laboratory was funded by the Pittsburgh Energy Technology Center, US Department of Energy, to investigate the potential utility of microorganisms for the solubilization of low-ranked coals. Our approach has been multifacited, including studies of the types of microorganisms involved, appropriate conditions for their growth and coal-solubilization, the suceptibility of different coals to microbial action, the chemical and physical nature of the product, and potential bioprocess designs. A substantial number of fungal species have been shown to be able to solubilize coal. Cohen and Gabrielle reported that two lignin-degrading fungi, Polyporous (Trametes) versicolor and Poria monticola couldmore »« less
