Influence of culture parameters on lignin metabolism byPhanerochaete chrysosporium
Culture parameters influencing metabolism of synthetic14C-lignins to14CO2 in defined media have been studied in shallow batch cultures of the ligninolytic wood-destroying HymenomycetePhanerochaete… Expand
Biotechnology of succinic acid production and markets for derived industrial products
Abstract Succinic acid, derived from fermentation of agricultural carbohydrates, has a specialty chemical market in industries producing food and pharmaceutical products, surfactants and detergents,… Expand

The current prospects for a bio-based succinate industry are described, with emphasis on specific bacteria that show the greatest promise for industrial succinate production, and the succinate-producing characteristics and the metabolic pathway used by each bacterial species are described. Expand
The biology of methanogenic bacteria.

The objective of the study was to establish an experimental procedure and show direct AFM measurements that unequivocally can be assigned as autotrophic growth rates in Methanobacterium thermoautotrophicum. Expand
Improved fuel cell and electrode designs for producing electricity from microbial degradation.
The results show that the amount of electrical energy produced by microbial fuel cells can be increased 1,000-fold by incorporating electron mediators into graphite electrodes and imply that sewage sludge may contain unique electrophilic microbes that transfer electrons more readily than E. coli.

Electricity Generation in Microbial Fuel Cells Using Neutral Red as an Electronophore
ABSTRACT Neutral red (NR) was utilized as an electron mediator in microbial fuel cells consuming glucose to study both its efficiency during electricity generation and its role in altering anaerobic… Expand
Ethanol Production by Thermophilic Bacteria: Relationship Between Fermentation Product Yields of and Catabolic Enzyme Activities in Clostridium thermocellum and Thermoanaerobium brockii
Significant quantitative differences in end-product yields by two strains of Clostridium thermocellum and one strain of Thermoanaerobium brockii were observed during cellobiose fermentation. Most… Expand

Graphite anodes incorporating microbial oxidants are evaluated in the laboratory relative to plain graphite with the goal of increasing power density by increasing current density and it was found that these anodes possess between 1.5- and 2.2-fold greater kinetic activity than plaingraphite. Expand
Carbon Monoxide Oxidation by Methanogenic Bacteria
Growth on CO agrees with the finding that cell-free extracts of M. thermoautotrophicum exhibited several characteristic properties found for the enzyme of Clostridium pasteurianum but differed mainly in that the clostridial enzyme did not utilize F(420) as the electron acceptor. Expand
