Centrifugal Flotation Applied to the Separation of Oil and Fat from WastewaterNew flotation devices such as flotation cyclones and flotation centrifuges have successfully been demonstrated for the beneficiation of coal. In this project a flotation centrifuge developed for that purpose was modified and applied to the treatment of wastewater from a food processing plant containing emulgated oil and fat. The cleaning efficiency of the flotation centrifuge was determine... ... hiện toàn bộ

Elicitation: A biotechnological tool for enhanced production of secondary metabolites in hairy root culturesAbstract Elicitation is a possible aid to overcome various difficulties associated with the large‐scale production of most commercially important bioactive secondary metabolites from wild and cultivated plants, undifferentiated or differentiated cultures. Secondary metabolite accumulation in vitro or their efflux in culture medium has been elicited in the undifferen... ... hiện toàn bộ

Next‐generation bioproduction systems: Cell‐free conversion concepts for industrial biotechnologyWithin the last decade, biotechnology gained pace in substituting petro‐based products for the chemical industries. This is visible with the appearance of bio‐based products in the market, from biosurfactants to bio‐based polymers like polylactic acid to bio‐ethylene. These technologies are mainly based on established fermentation technologies fostered by the use of renewable resources, cu... ... hiện toàn bộ

Analysis of intracellular metabolites of Corynebacterium glutamicum at high cell density with automated sampling and filtration and assessment of engineered enzymes for effective l ‐lysine productionEngineering of enzymes and pathways is generally required for the development of efficient strains for bioproduction processes. To this end, quantitative and reliable data of intracellular metabolites are highly desired, but often not available, especially for conditions more close to industrial applications, i.e. at high cell density and product concentration. Here, we investigated the in... ... hiện toàn bộ

Automated fast filtration and on‐filter quenching improve the intracellular metabolite analysis of microorganismsTo reliably determine intracellular metabolite concentrations in microorganisms, accurate sampling and sample inactivation strategies are crucial. Here, we present a method for automated fast filtration and on‐filter quenching of microbial samples to overcome metabolite leakage induced by cold shock and significantly reduce the sampling and treatment time compared to manual filtration meth... ... hiện toàn bộ

Improved electrocompetence and metabolic engineering of Clostridium pasteurianum reveals a new regulation pattern of glycerol fermentationAbstract Clostridium pasteurianum produces industrially valuable chemicals such as n ‐butanol and 1,3‐propanediol from fermentations of glycerol and glucose. Metabolic engineering for increased yields of selective compounds is not well established in this microorganism. In order to study carbon fluxes and to selec...

Metabolomic and kinetic investigations on the electricity‐aided production of butanol by Clostridium pasteurianum strainsAbstract In this contribution, we studied the effect of electro‐fermentation on the butanol production of Clostridium pasteurianum strains by a targeted metabolomics approach. Two strains were examined: an electrocompetent wild type strain (R525) and a mutant strain (dhaB mutant) lacking formation of 1,3‐propanediol (PDO). The dhaB‐negativ... ... hiện toàn bộ

A novel All‐in‐One electrolysis electrode and bioreactor enable better study of electrochemical effects and electricity‐aided bioprocessesAbstract An autoclavable All‐in‐One electrolysis electrode in a rod shape assembly is developed as a new tool for bioelectrochemical systems and electricity‐aided bioprocesses. It can replace the classic two‐chamber bioelectrochemical system for electrolysis reactions, be inserted into conventional bioreactors and is easily adaptable as electrocatalytic surface or g... ... hiện toàn bộ
