Bioprocess optimization for the production of aromatic compounds with metabolic...

The most common route to produce aromatic chemicals organic compounds containing at least one benzene ring in their structure is chemical synthesis. These processes, usually starting from an extracted fossil oil molecule such as benzene, toluene, or xylene, are highly environmentally unfriendly due to the use of non-renewable raw materials, high energy consumption and the usual production of toxic by-products. ...

Modulation of the central carbon metabolism of Corynebacterium glutamicum impro...

In recent years microorganisms have been engineered towards synthesizing interesting plant polyphenols such as flavonoids and stilbenes from glucose. Currently, low endogenous supply of malonylCoA, indispensable for plant polyphenol synthesis, impedes high product titers. Usually, limited malonylCoA availability during plant polyphenol production is avoided by supplementing fatty acid synthesisinhibiting antibi...

Heterologous production of resveratrol in bacterial hosts: currentstatus and pe...

The polyphenol resveratrol (3,5,4-trihydroxystilbene) is a well-known plant secondary metabolite, commonly used as a medical ingredient and a nutritional supplement. Due to its health-promoting properties, the demand for resveratrol is expected to continue growing. This stilbene can be found in different plants, including grapes, berries (blackberries, blueberries and raspberries), peanuts and their derived foo...

Impact of the cultivation strategy on resveratrol production from glucose in en...

The health benefits of polyphenols such as stilbenes and flavonoids for humans are increasingly attracting attention. Resveratrol is awell-characterized naturally-occurring stilbeneandpotentanti-oxidant, which isused as food supplement and cosmetic ingredient. Several microorganisms including Corynebacterium glutamicum were engineered for resveratrol production from glucose. Based on the cultivation of a resverat...

ARch4maps: A mobile augmented reality tool to enrich paper maps

This paper describes an augmented reality app running on a Windows tablet that recognizes image features on a city paper map and overlays, in real-time, digital content related to the relevant buildings of the city. The system register in 3D the location of those buildings in the map, enriching the user experience with several multimedia information per building: image, text and 3D models which can be explored ...

Routine screening of harmful microorganisms in beach sands: implications to pub...

Beaches worldwide provide recreational opportunities to hundreds of millions of people and serve as important components of coastal economies. Beach water is often monitored for microbiological quality to detect the presence of indicators of human sewage contamination so as to prevent public health outbreaks associated with water contact. However, growing evidence suggests that beach sand can harbor microbes ha...

Determinants of food choice at work: exploratory study in food service

Determinantes da escolha alimentar no trabalho: Estudo exploratório no setor de...

Several studies highlight the high proportion of meal production services' workers with overweight, which has been associated with the change in eating habits after the beginning of activity in this sector. The aims of this study were: to evaluate the weight status of employees in the meal production sector; to identify the main determinants of these workers' food choice; and to compare these results with data ...

Changes in the Clonal Nature and Antibiotic Resistance Profiles of Methicillin-...

Abstract Two hundred eighty methicillin-resistant Staphylococcus aureus (MRSA) clinical isolates recovered from a tertiary care hospital in Oporto, Portugal, between 2003 and 2005 were studied by a combination of molecular typing techniques in order to investigate the genetic backgrounds associated with the changes in the resistance phenotypes observed since 2001 and compare them to those previously found in th...
