ALACEN: A Holistic Herbaceous Biomass Fractionation Process Attaining a Xylose-Rich Stream for Direct Microbial Conversion to Bioplastics

Bertran Llorens, Salvador; Zhou, Wen; A. Palazzolo, Martin; Colpa, Dana; Euverink, Gert Jan Willem; Krooneman, Janneke (Bioconversion And Fermentation Technology); Deuss, Peter

Lignocellulose biorefining is a promising technologyfor the sustainable production of chemicals and biopolymers.Usually, when one component is focused on, the chemical natureand yield of the others are compromised. Thus, one of thebottlenecks in biomass biorefining is harnessing the maximumvalue from …

Conversion of a Xylose-rich Stream from Biomass-biorefining into Polyhydroxyalkanoate (PHA) by Schlegelella thermodepolymerans

Krooneman, Janneke (Bioconversion And Fermentation Technology); Bertran Llorens, Salvador; Zhou, Wen; Palazzolo, Martin A.; Colpa, Dana; Euverink, Gerrit Jan Willem; Deuss, Peter

The transition to a biobased economy necessitates utilizing renewable resources as a sustainable alternative to traditional fossil fuels. Bioconversion is a way to produce many green chemicals from renewables, e.g., biopolymers like PHAs. However, fermentation and bioconversion processes mostly rely …

Polyhydroxyalkanoates (PHAs) synthesis and degradation by microbes and applications towards a circular economy

Zhou, Wen; Bergsma, Simon; Colpa, Dana Irene; Euverink, Gert-Jan Willem; Krooneman, Janneke (Bioconversion And Fermentation Technology)

Overusing non-degradable plastics causes a series of environmental issues, inferring a switch to biodegradable plastics. Polyhydroxyalkanoates (PHAs) are promising biodegradable plastics that can be produced by many microbes using various substrates from waste feedstock. However, the cost of PHAs production …

Influence of online collaborative learning on social network and academic performance of medical students: lessons learned from the COVID-19 pandemic

Zhou, Yan; Xu, Xiaoming; Adema, Johanna (Music In Context); Brouwer, Jasperina; Bos, Nicolaas A.; Diemers, Agnes

Inleiding: De sociale afstandbeperkingen als gevolg van de COVID-19 pandemie hebben de leeromgeving van studenten veranderd en hun sociale interacties beperkt. Daarom was het doel van deze studie om de invloed van de sociale afstandsbeperkingen op de sociale netwerken, het welzijn en de academische prestaties …

Insight into polyhydroxyalkanoate (PHA) production from xylose and extracellular PHA degradation by a thermophilic Schlegelella thermodepolymerans

Zhou, Wen; Colpa, Dana; Permentier, Hjalmar; Offringa, Ruben Ate; Rohrbach, Leon; Euverink, Gert Jan Willem; Krooneman, Janneke (Bioconversion And Fermentation Technology)

Accumulation of non-degradable plastic waste in the environment might be prevented by the use of biodegradable polyhydroxyalkanoate (PHA). In this study, the thermophile Schlegelella thermodepolymerans produced up to 80 wt% PHA based on dry cell mass. The largest PHA granules were found in the cells …

The impact of carbon to nitrogen ratios and pH on the microbial prevalence and polyhydroxybutyrate production levels using a mixed microbial starter culture

Zhou, Wen; Colpa, Dana; Geurkink, Bert; Euverink, Gerrit Jan Willem; Krooneman, Janneke (Bioconversion And Fermentation Technology)

Growth conditions have been frequently studied in optimizing polyhydroxybutyrate (PHB) production, while few studies were performed to unravel the dynamic mixed microbial consortia (MMCs) in the process. In this study, the relationship between growth conditions (C/N ratios and pH) and the corresponding …

Thauera aminoaromatica MZ1T Identified as a Polyhydroxyalkanoate-Producing Bacterium within a Mixed Microbial Consortium

Colpa, Dana; Zhou, Wen; Wempe, Jan Pier; Tamis, Jelmer; Krooneman, Janneke (Bioconversion And Fermentation Technology); Euverink, Gerrit Jan Willem; Stuart, Marc C. A.

Polyhydroxyalkanoates (PHAs) form a highly promising class of bioplastics for the transition from fossil fuel-based plastics to bio-renewable and biodegradable plastics. Mixed microbial consortia (MMC) are known to be able to produce PHAs from organic waste streams. Knowledge of key-microbes and their …

The influence of privacy on the acceptance of technologies for assisted living

Jaschinski, Christina; Ben Allouch, Somaya (Lectoraat Digital Life); Peters, Oscar; van Dijk, Jan; Gao, Qin; Zhou, Jia

With population aging and the expected shortage of formal and informal caregivers, emerging technologies for assistive living are on the rise. Focusing on the perspective of the prospective users of these technologies, this study investigates the perceived drivers and barriers that influence AAL adoption. …
