Available in PDF, EPUB and Kindle. Book excerpt: Completely mechanistic mathematical models have been developed to examine the dynamic behavior of bioavailability-limited substrate utilization in a competitive microbial system experiencing protozoan predation pressure in continuously mixed open-flow (CMFR) and batch reactors to examine the effects of various processes on the bioremediation process. Mechanistic processes incorporated into the models include: (1) growth inhibition of one bacterial species, (2) selective predation by protozoa using a novel "contact-complex" formation mechanism, (3) adoption of defense mechanisms by bacteria against predation, (4) incorporation of spatial refuge provided by sediment particles, (5) heterotrophic consumption of non-living organic carbon exudates produced by bacteria and protozoa and (6) bioavailability limited microbial substrate utilization. Sensitivity analyses were performed by simulation of the multi-parameter non-steady state models to focus research on the parameters that affect the overall process of bioremediation most significantly. The results of the simulations demonstrate that growth inhibition, selective predation by protozoa and the adoption of defense mechanisms all allow the two prey species and predator to co-exist in the system resulting in enhanced substrate removal. The biokinetic parameters that control the overall substrate utilization rate are dilution rate (CMFR only), prey and predator endogenous decay rate and the predator growth rate. Also, the CMFR is more dynamic compared to the batch reactor system. The results suggest that a more "biodiverse" microbial community enhances the bioremediation process. In addition, abiotic studies were performed to better understand bioavailability limitations and the role pore transport plays in the bioremediation process using naphthalene and phenanthrene in low organic carbon ( foc) engineered particles. The results indicate that sorption non-linearity does not significantly affect bioavailability of the substrate (assuming either local equilibrium or first order micropore domain resistance for intra-particle pore transport) in low foc geosorbents (such as in the test system or aquifer material). In contrast, in high foc geosorbents (such as surface soils and sediments), sorption non-linearity will result in greatly decreased bioavailability and much greater remediation time scales. These results help us understand how various model parameters and bioavailability limitations affect remediation outcomes, and hopefully leading towards better management of the contaminated soils and sediments.

Available in PDF, EPUB and Kindle. Book excerpt: Predicting the growth and behaviour of microorganisms in food has long been an aim in food microbiology research. In recent years, microbial models have evolved to become more exact and the discipline of quantitative microbial ecology has gained increasing importance for food safety management, particularly as minimal processing techniques have become more widely used. These processing methods operate closer to microbial death, survival and growth boundaries and therefore require even more precise models. Written by a team of leading experts in the field, Modelling microorganims in food assesses the latest developments and provides an outlook for the future of microbial modelling. Part one discusses general issues involved in building models of microbial growth and inactivation in foods, with chapters on the historical background of the field, experimental design, data processing and model fitting, the problem of uncertainty and variability in models and modelling lag-time. Further chapters review the use of quantitative microbiology tools in predictive microbiology and the use of predictive microbiology in risk assessment. The second part of the book focuses on new approaches in specific areas of microbial modelling, with chapters discussing the implications of microbial variability in predictive modelling and the importance of taking into account microbial interactions in foods. Predicting microbial inactivation under high pressure and the use of mechanistic models are also covered. The final chapters outline the possibility of incorporating systems biology approaches into food microbiology. Modelling microorganisms in food is a standard reference for all those in the field of food microbiology.

This book was released on 2013-03-09 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for the conference held at Bombannes, France in May, 1982 arose out of a Scientific Committee on Oceanic Research (SCOR) Working Group on "Mathematical Models in Biological Oceanography". This group was chaired by K.H. Mann and held two meetings in 1977 and 1979. At both meetings it was felt that, although reductionist modelling of marine ecosystems had achieved some successes, the future progress lay in the development of holistic ecosystem models. The members of the group (K.H. Mann, T. Platt, J.M. Colebrook, D.F. Smith, M.J.R. Fasham, J. Field, G. Radach, R.E. Ulanowicz and F. Wulff) produced a critical review of reductionist and holistic models which was published by the Unesco Press (Platt, Mann and Ulanowicz, 1981). One of the conclusions of this review was that, whether holistic or reductionist models are preferred, it is critically important to increase the scientific effort in the measurement of physiological rates for the computation of ecological fluxes. The Working Group therefore recommended that an international meeting should be organized which would attempt to bring together theoretical ecologists and biological oceanographers to assess the present and future capability for measuring ecological fluxes and incorporating these data into models. An approach was made to the Marine Sciences Panel of the NATO Science Committee who expressed an interest in funding such a meeting. They awarded a planning grant and a planning group was formed consisting of M.J.R. Fasham, M.V. Angel, T. Platt, R.E.

Available in PDF, EPUB and Kindle. Book excerpt: Four authors with backgrounds in food microbiology, food chemistry, mathematics, and statistics, explain how techniques of predictive microbiology can allow an objective evaluation of the effects of processing, distribution, and storage on the microbiological safety and quality of foods. The trick is to understand the microbial ecology of a process or of a food at a particular point in the chain, then use mathematical relationships between microbial growth and the expected environmental conditions, to predict the growth or survival of selected organisms.
