Environmental Biotechnology : Principles and Applications 1st Ed. Rittmann, Bruce E. Environmental Biotechnology: Principles and Applications Request. Rittmann, B. In Equation 2. Thus, casein is the electron—donor substrate. The rest of the carbon in casein is incorporated into the newly synthesized biomass, because casein also is the carbon source.

The complex protein—containing mixture in casein is represented through the empirical formula C8HN2. This formula was constructed from knowledge of the relative mass proportions of organic carbon, hydrogen, oxygen, and nitrogen contained in the wastewater, values that can be obtained from normal organic chemical analyses for each element present.

The same approach is taken for the empirical formula for bacterial cells of C5HN. Bacterial cells are highly complex structures containing a variety of car- bohydrates, proteins, fats, and nucleic acids, some with very high molecular weights. Indeed, microorganisms contain many more than the four elements indicated by the above equation, such as phosphorus, sulfur, iron, and many other elements that are generally present in only trace amounts.

An empirical formula could contain as many elements as desired, as long as the relative proportions on a mass basis are known. However, Porges et al.

The mass requirements for elements not shown in the formula can be determined once the mass of bacterial cells formed from a given reaction is known. For example, phosphorus normally represents about 2 percent of the bacterial organic dry weight. Purges et a1. Could we predict the stoichiometry of such a reaction? The answer is yes, and the rest of the chapter develops and applies an approach for doing this.

To achieve this goal, we need three things: 1. Empirical formula for cells 2. Means to relate the proportion of the electron—donor substrate that is used to synthesize new biomass to the energy gained from catabolism and the energy needed for anabolism. These three items are presented in order in the rest of this chapter.

However, the relative proportion of elements actually present in cells depends on the characteristics of the microorganisms involved, the substrates being used for energy, and the availability of other nutrients required for microbial growth.

Table 2. An extremely important way to compare empirical cell formulas is by the ratio of oxygen required for full oxidation of the cellular carbon per unit weight of cells. This normally is equal to the chemical oxygen demand COD , which is a standard chemical procedure for evaluating this quantity and is based on the reduction of dichromate in a boiling acid solution.

Microbial Ecology Pushes Frontiers in Biotechnology

CHL95N 1. The iaboratory evaporates the sample to dryness and then places it in an oven overnight at DC to drive off ail water present. Various microorganisms that exhibit the potential to degrade and detoxify various types of pollutants, including xenobiotic compounds and toxic metals, have been isolated 20 , In addition, recent advances in molecular and genomic techniques, including metagenomics and metatranscriptomics, have accelerated the understanding of metabolic pathways and genetic functions underlying bioremediation processes 4.

The importance of interspecies interactions has been demonstrated among biodegradative microbes.

For example, the findings of recent studies have indicated that the reductive dechlorination of polychlorinated dipenzo-p-dioxins and oxidative degradation of dechlorinated products occur simultaneously in semi-anaerobic microbial microcosms, which facilitates their complete dechlorination 11 , Microorganisms also have the potential to remove various toxic metals from contaminated environments by altering their chemical speciation and oxidation states.

For example, some dissimilatory metal-reducing bacteria are known to possess the ability to reduce the soluble oxidized form of uranium, U VI , to insoluble U IV , thereby preventing from their further spread to uncontaminated sites Recent studies also characterized U-tolerant bacterial communities in subsurface U ore deposits On the other hand, microorganisms that can reduce arsenate [As V ] to arsenite [As III ], which has greater toxicity and hydrological mobility than arsenate, have also been discovered, and the molecular mechanisms responsible for arsenate reduction have been identified In addition, studies reported the isolation and characterization of As III -and antimonite [Sb III ]-oxidizing bacteria that potentially contribute to the speciation and mobility of Sb and As in situ 9.

Although these processes have yet to be practically applied to large-scale environmental restoration, a better understanding of microbe-metal interactions will contribute to the search for new remediation strategies. We herein introduced recent highlights in microbial ecology that are relevant to wastewater treatment, anaerobic digestion, microbial fuel cells, and bioremediation.

Although the engineering techniques used and microbes involved in these processes are different, microbial ecology is the common science that provides an interdisciplinary understanding of the microbes involved. On the other hand, we suggest that these processes serve as model ecosystems that can be used to assess novel theories in microbial ecology. Therefore, environmental biotechnology and microbial ecology are expected to co-evolve based on technical advancements and social needs.
