Multi-agent system for multimodal machine learning object detection

Multi-agent systems have shown great promise in addressing complex problems that traditional single-agent approaches are not be able to handle. In this article, we propose a multi-agent system for the conception of a multimodal machine learning problem on edge devices. Our architecture leverages docker containers to encapsulate knowledge in the form of models and processes, enabling easy management of the syste...

Exploiting non-conventional yeasts for low-alcohol beer production

Non-Saccharomyces yeasts represent a very appealing alternative to producing beers with zero or low ethanol content. The current study explores the potential of seven non-Saccharomyces yeasts to produce low-alcohol or non-alcoholic beer, in addition to engineered/selected Saccharomyces yeasts for low-alcohol production. The yeasts were first screened for their sugar consumption and ethanol production profiles, ...

Bioreactors and engineering of filamentous fungi cultivation

Filamentous fungi have been growingly used to produce many compounds we use on a daily basis, such as antibiotics and enzymes, or even to treat industrial effluents. While some of these processes have been established for decades, the rise of new production platforms combined with the continuous development of traditional processes makes fungal biotechnology a current trend. A key element in fungal biotechnolog...

Electronic cigarette aerosol: impact on embryonic lung morphology

Introduction: Smoking is a major public health problem responsible for 700000 deaths/year in Europe. Conventional cigarettes (c-cig) exacerbates several health issues, such as chronic obstructive pulmonary disease, fibrosis and cancer. Tobacco use during pregnancy has serious consequences to infants, since they become more susceptible to develop congenital disorders, lung diseases and sudden death. Electronic c...

Production of blueberry wine and volatile characterization of young and bottle-...

The aim of this study was the production of blueberry wine and the characterization of the volatile compounds of fermented and aging in bottle products. Multivariate data analysis indicated similarity of volatile compounds released when fermentations were conducted at laboratoryscale and midscale, with the exception of one replicate creating a distinctive group characterized by low concentrations of acetaldehyd...

Metabolic engineering of Ashbya gossypii for deciphering the de novo biosynthes...

Background Lactones are highly valuable cyclic esters of hydroxy fatty acids that find application as pure fragrances or as building blocks of speciality chemicals. While chemical synthesis often leads to undesired racemic mixtures, microbial production allows obtaining optically pure lactones. The production of a specific lactone by biotransformation depends on the supply of the corresponding hydroxy fatty aci...

Factors affecting extraction of adsorbed wine volatile compounds and wood extra...

During ageing, wood adsorbs volatile compounds from beverages. However, chemical interactions involved in sorption still remain unclear, as well as wood capacity to transfer such compounds to subsequent matrices when reused. Therefore, extractions were conducted from used wood manipulating variables such as ethanol concentration, contact temperature and pH, in order to determine their effect in the interaction ...

Volatile fingerprinting differentiates diverse-aged craft beers

Supplementary data to this article can be found online at https:// doi.org/10.1016/j.lwt.2019.03.044.; Beer ageing on wood is a complex and difficult to control process involving several reactions and compounds. Difficulties in understanding the underlying phenomena often lead to empirical and unpredictable processes and heterogeneous products. This work resorts to volatile fingerprinting along with multivariat...

Volatile compounds profiling and engineering of Ashbya gossypii strains for de ...

Lactones are highly valuable cyclic esters of hydroxy fatty acids that fi nd application as pure fragrance compounds or as building blocks for fi ne/specialty chemicals synthesis1. While chemical synthesis often leads to undesired racemic mixtures, the microbial production of lactones offers the possibility to obtain optically pure lactones from natural sources. Therefore, the biotransformation of hydroxy fatty...
