Proceedings Winter 2008 February 2008 PROCEEDINGS Technical Advisory Conference Center for Biofilm Engineering About the Center for Biofilm Engineering CBE Leadership: Director and Executive Committee Phil Stewart, CBE Director and Professor, Chemical & Biological Engineering Anne Camper, Associate Dean for Research, College of Engineering and Professor, Civil Engineering Al Cunningham, Professor, Civil Engineering Brent Peyton, Associate Professor, Chemical & Biological Engineering Paul Sturman, CBE Industrial Coordinator A Brief History of the CBE The CBE was established in 1990 with a grant from the National Science Foundation‘s Engineering Research Centers program. The NSF-ERC program was created to increase U.S. industrial competitiveness and to re-invent science and engineering education in U.S. universities. Under the leadership of its founding director, Bill Characklis, the new engineering center also drew support from the State of Montana, Montana State University, and industrial partners gathered during its pre-1990 work as the Institute for Biological and Chemical Process Analysis. Since the beginning, CBE researchers have been recognized nationally and internationally for leading- edge biofilm research, and for taking an interdisciplinary approach to the study of microbial growth on surfaces. In the spring of 2001 the CBE‘s 11-year period of NSF-ERC program support drew to a close. The CBE‘s continued success is built on the foundation of many years of productive university-industry-government collaboration in pursuit of its vision to be a world leader in fundamental research, science and engineering education, and industrially relevant technology. Mission and Goals of the CBE The mission of the Center for Biofilm Engineering is to advance the basic knowledge, technology and education required to understand, control and exploit biofilm processes. The CBE has identified goals in three primary areas of activity. In the area of research, the CBE‘s goal is to do leading-edge fundamental research to elucidate mechanisms at work in bacterial biofilms. The CBE has been a leader in defining the structure and function of biofilms on surfaces, in understanding antimicrobial resistance mechanisms of biofilm, and in identifying the role of signal molecules in controlling bacterial behavior. Researchers at the CBE have demonstrated that biofilms are multicellular attached communities with primitive circulatory systems and a measure of cellular specialization. Understanding these ―biofilm basics‖ presents opportunities for developing more effective strategies to control biofilms in industrial settings. The second goal of the CBE is to make its research relevant to real systems, where the information can be applied. Industrial concerns shape and focus the research efforts. Technology transfer at the CBE involves not only information, but methods and technology development. Education is at the heart of the CBE‘s success. The CBE‘s third goal is to sustain productive interdisciplinary undergraduate and graduate education programs involving team research on industrially relevant projects.

In recent years, some approaches have been proposed for identifying microbial interaction network. These methods often focus on one dataset without considering the advantage of data integration. In this study, we propose to use a similarity network fusion (SNF) method to infer microbial relations. The SNF efficiently integrates the similarities of species derived from different datasets by a cross-network diffusion process. We also introduce consensus k-nearest neighborhood (Ck-NN) method instead of k-NN in the original SNF (we call the approach CSNF). The final network represents the augmented species relationships with aggregated evidence from various datasets, taking advantage of comple- mentarity in the data. We apply the method on genus profiles derived from three microbiome datasets and we find that CSNF can discover the modular structure of microbial interaction network which cannot be identified by analyzing a single dataset. species interaction, metagenome, diffusion process, biological network, modularity Citation: Jiang XP, Hu XH.

  • Understanding the Interaction Between Anabaena Sp. and a Heterocyst-Specific Epibiont
    Understanding the interaction between Anabaena sp. and a heterocyst-specific epibiont Iglika V. Pavlova MBL Microbial Diversity course 2005 Abstract Anabaena sp. and an associated heterocyst-specific epibiontic bacterium were isolated from School Street Marsh in Woods Hole, MA in 1997 during the Microbial Diversity course. A two-member culture of the cyanobacterium and the epibiont have been maintained at WHOI by John Waterbury. Anabaena species with similar heterocyst-specific epibionts have also been isolated from other locations (7, 8, 9). Successful culture of the epibiont separately from the School Street Marsh cyanobacterium was achieved on two occasions (1, 10), but the isolates were not preserved. The epibiont was identified to be an α-proteobacterium within the Rhizobiaceae group (10). The close and specific association between the cyanobacterium and the epibiont strongly suggests there might be a physiological benefit or benefits to the cyanobacterium, the epibiont, or to both partners. This study was designed to understand the potential benefits of the interaction for the epibiontic bacterium. Several approaches were used to isolate the epibiont in pure culture, unsuccessfully. This report describes the rationale for undertaking the project and the approaches used to isolate the epibiont, in the hopes that this will be useful information for the future isolation of an axenic epibiont culture. Rationale Cyanobacterial associations with heterotrophic bacteria from environmental isolates have been described before and have been implicated in increasing the growth of the cyanobacterium (5, 6, 7). Benefit to the cyanobacterium may be derived from a range of associations, including the presence of heterotrophic bacteria in the culture medium, attraction of such bacteria to cyanobacterial secretions (either along the whole filament, or secretions stemming from the heterocyst in filamentous bacteria), or the attachment of the bacterium to the cyanobacterium outer surface (5, 6, 7, 9).

    Antonie van Leeuwenhoek 39 (1973) 545-565 545 A theoretical study on the amount of ATP required for synthesis of microbial cell material A. H. STOUTHAMER Biological Laboratory, Free University, de Boelelaan 1087, Amsterdam, the Netherlands STOUTHAMER, A.H. 1973. A theoretical study on the amount of ATP required for synthesis of microbial cell material. Antonie van Leeuwenhoek 39: 545-565. The amount of ATP required for the formation of microbial cells growing under various conditions was calculated. It was assumed that the chemical com­ position of the cell was the same under all these conditions. The analysis of the chemical composition of microbial cells of Morowitz ( 1968) was taken as a base. It was assumed that 4 moles of ATP are required for the incorporation of one mole of amino acid into protein. The amount of ATP required on account of the instability and frequent regeneration of messenger RNA was calculated from data in the literature pertaining to the relative rates of synthesis of the various classes of RNA molecules in the cell. An estimate is given of the amount of ATP required for transport processes. For this purpose it was assumed that 0.5 mole of ATP is necessary for the uptake of 1 g-ion of potassium or ammo­ nium, and 1 mole of ATP for the uptake of 1 mole of phosphate, amino acid, acetate, malate etc. The results of the calculations show that from preformed monomers (glucose, amino acids and nucleic acid bases) 31.9 g cells can be formed per g-mole of ATP when acetyl-CoA is formed from glucose.

  • Aerobic Microorganism' William B
    THE RELATION OF OXIDATION-REDUCTION POTENTIAL TO THE GROWTH OF AN .AEROBIC MICROORGANISM' WILLIAM B. WOOD, JR., MARY LEE WOOD AND I. L. BALDWIN University of Wisconsin Received for publication August 2, 1935 INTRODUCTION The possible relationship between the oxidation-reduction po- tentials of culture media and the ability of micro6rganisms to initiate growth has recently interested bacteriologists. The work of Aubel and Aubertin (1927), Dubos (1929a), Fildes (1929), Knight and Fildes (1930), Plotz and Geloso (1930), and others, has established the fact that the growth of certain anaerobes is greatly influenced by the oxidation-reduction potential of the medium. In the case of aerobic bacteria, however, conflicting results have been reported. Allyn and Baldwin (1930, 1932) demonstrated that the potential of the medium was of consider- able importance in determining whether or not small inocula of Rhizobium, an aerobic organism, could initiate growth. Knaysi and Dutky (1934), on the other hand, finding that Bacillus mega- therium would not grow in the absence of dissolved oxygen, even when the potential of the mediuim was varied over a considerable range, concluded that "the limiting factor in the growth of Bacil- lus megatherium in vacuum is the oxygen content and not the oxidation-reduction potential of the culture medium." Their experiments offer no information, however, as to whether or not the potential of the medium affects the growth of this organism under aerobic conditions. The purpose of this paper is to report: (a) experimental evi- 1 Published with the approval of the Director of the Wisconsin Agricultural Experiment Station. 593 594 W.

  • Hypothesis Paper Why O2 Is Required by Complex Life on Habitable Planets and the Concept of Planetary “Oxygenation Time”
    5703_06_p415-438 5/27/05 1:30 PM Page 415 ASTROBIOLOGY Volume 5, Number 3, 2005 © Mary Ann Liebert, Inc. Hypothesis Paper Why O2 Is Required by Complex Life on Habitable Planets and the Concept of Planetary “Oxygenation Time” DAVID C. CATLING,1 CHRISTOPHER R. GLEIN,1 KEVIN J. ZAHNLE,2 and CHRISTOPHER P. MCKAY2 ABSTRACT Life is constructed from a limited toolkit: the Periodic Table. The reduction of oxygen provides the largest free energy release per electron transfer, except for the reduction of fluorine and chlorine. However, the bonding of O2 ensures that it is sufficiently stable to accumulate in a planetary atmosphere, whereas the more weakly bonded halogen gases are far too reactive ever to achieve significant abundance. Consequently, an atmosphere rich in O2 provides the largest feasible energy source. This universal uniqueness suggests that abundant O2 is necessary for the high-energy demands of complex life anywhere, i.e., for actively mobile organisms of -ϳ10؊1–100 m size scale with specialized, differentiated anatomy comparable to advanced meta zoans. On Earth, aerobic metabolism provides about an order of magnitude more energy for a given intake of food than anaerobic metabolism. As a result, anaerobes do not grow beyond the complexity of uniseriate filaments of cells because of prohibitively low growth efficiencies in a food chain. The biomass cumulative number density, n, at a particular mass, m, scales as n ,Ͼm)ؔm؊1 for aquatic aerobes, and we show that for anaerobes the predicted scaling is nؔm؊1.5) close to a growth-limited threshold. Even with aerobic metabolism, the partial pressure of at- ϳ 3 mospheric O2 (PO2) must exceed 10 Pa to allow organisms that rely on O2 diffusion to evolve ϳ ؊3 ϳ 3 4 ϳ ؊2 to a size 10 m.

  • History of Microbiology: Spontaneous Generation Theory
    HISTORY OF MICROBIOLOGY: SPONTANEOUS GENERATION THEORY Microbiology often has been defined as the study of organisms and agents too small to be seen clearly by the unaided eye—that is, the study of microorganisms. Because objects less than about one millimeter in diameter cannot be seen clearly and must be examined with a microscope, microbiology is concerned primarily with organisms and agents this small and smaller. Microbial World Microorganisms are everywhere. Almost every natural surface is colonized by microbes (including our skin). Some microorganisms can live quite happily in boiling hot springs, whereas others form complex microbial communities in frozen sea ice. Most microorganisms are harmless to humans. You swallow millions of microbes every day with no ill effects. In fact, we are dependent on microbes to help us digest our food and to protect our bodies from pathogens. Microbes also keep the biosphere running by carrying out essential functions such as decomposition of dead animals and plants. Microbes are the dominant form of life on planet Earth. More than half the biomass on Earth consists of microorganisms, whereas animals constitute only 15% of the mass of living organisms on Earth. This Microbiology course deals with • How and where they live • Their structure • How they derive food and energy • Functions of soil micro flora • Role in nutrient transformation • Relation with plant • Importance in Industries The microorganisms can be divided into two distinct groups based on the nucleus structure: Prokaryotes – The organism lacking true nucleus (membrane enclosed chromosome and nucleolus) and other organelles like mitochondria, golgi body, entoplasmic reticulum etc. are referred as Prokaryotes.
