Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with human and animal health as well as the preservation of the environment by reducing the use of chemical pesticides pollutants used in agriculture for pest control and the presence of safe biological solutions. In response to that, there is considerable interest in finding alternative control approaches for use in integrated pest management strategies for crop diseases. In Egypt, we have to agree that the plant disease biological control is still in a period of 'undeveloped'. For this purposes, this research has a national impact, as it results to reach the final stage of industrial scale, maintaining its biocontrol efficacy. The purpose of conducting this study, was to optimize the conditions for microbial biomass production of the biocontrol agent by describing the effect of various technical methods on fermentation and chemical compositions of medium and substrate. Various fermentation strategies can also be used to improve yield and productivity of biomass. The new proposed design of operating condition in bioreactor enabled us to introduce a new model controlled with optimized biocontrol product

Download or read book Strain Engineering and Process Design for Continuous Surfactin Production in Biofilm Bioreactors with Bacillus Subtilis 168 written by Hannah Luise Brück and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofilm bioreactors show promise for continuous microbial biosurfactant production due to the natural robustness of self-immobilized cells and the possible design of processes avoiding foam formation. The widely used bacterial strain B. subtilis 168 has the potential to produce surfactin, a powerful biosurfactant with exceptional biological activities and various industrial applications. However, B. subtilis 168 exhibits only poor biofilm formation capacities and thus entails limited cell adhesion capacities. In order to improve the natural cell immobilization of B. subtilis 168 to adapt this strain better to biofilm cultivation, filamentous mutant strains with restored exopolysaccharide (EPS) production were generated. The impacts of the genetic modifications were evaluated through colonization assays and by measuring the biofilm formation capacity under low shear stress in a drip-flow reactor (DFR). Subsequently, the most performant strains were selected and cultivated in a newly designed continuous trickle-bed biofilm bioreactor containing highly structured metal packing elements for biofilm formation. Moreover, a bacterial growth model was built able to describe the growth dynamics of the planktonic cell and biofilm population in the system. The colony development was strongly affected by filamentous cell growth and EPS production which was manifested through an enhanced surface spreading and colonization capacity. In the DFR and trickle-bed biofilm bioreactor, the EPS+ mutants showed significantly increased performances regarding the biofilm formation and surfactin production capacities. Whereas cell filamentation had a minor impact on the processes, but contributed to a better cell cohesion in the biofilm and led to reduced cell detachment during the cultivation. Thus, EPS production and filamentous cell growth contributed considerably to an improved process performance in the system. In addition, continuous fermentation has shown to be favorable for a high surfactin productivity. The experimental data from the trickle-bed biofilm bioreactor were in good accordance with those obtained by simulations with the developed growth model. Hence, the growth model has been successfully validated and could be used for further process optimization.

Available in PDF, EPUB and Kindle. Book excerpt: The microbial world has given us many surprises including microbes that grow under extremely harsh conditions (122C at 40 MPa), novel metabolisms such as the uranium and perchlorate reduction, and novel chemicals that can be used to control diseases. We continually face new and difficult problems such as the need to transition to more carbon-neutral energy sources and to find eco-friendly chemicals and to find new drugs to treat disease. Will it be possible to tap into the seemingly limitless potential of microbial activity to solve our current and future problems?The answer to this question is probably yes. We are already looking to the microbial world to provide new energy sources, green chemicals to replace those made from petroleum, and new drugs to fight disease. To help us along these paths, we are deciphering how microorganisms interact with each other. We know that microbial populations interact and communicate with each other. The language that microbes use is chemical where small molecules are exchanged among different microbial cells. Sometimes, these chemicals suppress activities of competitors and could be used as antibiotics or may have other therapeutic uses. Other times, the chemicals stimulate complex responses in microbial populations such as fruiting body or biofilm formation. By understanding the conversation that microbes are having among themselves, e. g.

Download or read book Biosurfactants for the Biobased Economy written by Rudolf Hausmann and published by Springer Nature. This book was released on 2022-06-30 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of current biosurfactant research and applications. Public awareness of environmental issues has increased significantly over the last decade, a trend that has been accompanied by industry demands for climate-friendly and environmentally friendly renewable raw materials. In the context of household products, biosurfactants could potentially meet this demand in the future due to their low ecotoxicity, excellent biodegradability, and use of renewable raw materials. The diversity of this class of molecules, which has only been marginally tapped to date, offers only an inkling of their future application potential. However, there are two main obstacles to their widespread commercial use on the growing surfactant market: the lack of attractive and competitive production technologies, and the limited structural diversity of commercially available biosurfactants. Addressing both of these core issues, this book will provide readers with a deeper understanding of the role of biosurfactants, including future opportunities and challenges.

This book was released on 2011-12-28 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book helps advance process safety in a key area of interest. Currently, no literature exists which is solely dedicated to process safety for the bioprocessing industry. There are texts, guidelines, and standards on biosafety at the laboratory level and for industrial hygiene, but no guidelines for large-scale production facilities. In fact, biosafety is largely defined as a field that promotes safe laboratory practices, procedures and use of containment equipment and facilities. Additionally, biomedical engineers, biologists, or other professionals without chemical engineering training or knowledge of inherently safe design are designing many of these facilities.
