Policastro, G. (author), Ebrahimi, S. (author), Weissbrodt, D.G. (author), Fabbricino, Massimiliano (author), van Loosdrecht, Mark C.M. (author)A dual-growth-limited continuous operated bioreactor (chemostat) was used to enhance lipid accumulation in an enrichment culture of microalgae. The light intensity and nitrogen concentration where both limiting factors resulting in high lipid accumulation in the mixed culture. Both conditions of light and nitrogen excess and deficiency were...journal article 2024

Calderon Franco, D. (author), van Loosdrecht, Mark C.M. (author), Abeel, T.E.P.M.F. (author), Weissbrodt, D.G. (author)The transformation of environmental microorganisms by extracellular DNA is an overlooked mechanism of horizontal gene transfer and evolution. It initiates the acquisition of exogenous genes and propagates antimicrobial resistance alongside vertical and conjugative transfers. We combined mixed-culture biotechnology and Hi-C sequencing to...journal article 2023

Cerruti, M. (author), Crosset-Perrotin, G. (author), Ananth, Mythili (author), Rombouts, Julius Laurens (author), Weissbrodt, D.G. (author)Fermentative chemoorganoheterotrophic bacteria (FCB) and purple photoorganoheterotrophic bacteria (PPB) are two interesting microbial guilds to process carbohydrate-rich wastewaters. Their metabolic interactions have been studied in pure cultures or co-cultures, but little is known about mixed cultures. We studied the effect of reactor...journal article 2023

Cerruti, M. (author), Stevens, B. (author), Ebrahimi, S. (author), Alloul, A. (author), Vlaeminck, Siegfried E. (author), Weissbrodt, D.G. (author)Mixed-culture biotechnologies are widely used to capture nutrients from wastewater. Purple non-sulfur bacteria (PNSB), a guild of anoxygenic photomixotrophic organisms, rise interest for their ability to directly assimilate nutrients in the biomass. One challenge targets the aggregation and accumulation of PNSB biomass to separate it from the...journal article 2020

Rombouts, J.L. (author), Mos, Galvin (author), Weissbrodt, D.G. (author), Kleerebezem, R. (author), van Loosdrecht, Mark C.M. (author)Efficient industrial fermentation of lignocellulosic waste containing a large part of glucose and xylose is desirable to implement a circular economy. Mixed culture biotechnologies can aid in realizing this goal. The effect of feeding equivalent substrates to a microbial community, such a xylose and glucose, is not well understood in terms of...journal article 2019
