Totlani, K. (author), van Tatenhove-Pel, R.J. (author), Kreutzer, M.T. (author), van Gulik, W.M. (author), van Steijn, V. (author)It is common practice in the development of bioprocesses to genetically modify a microorganism and study a large number of resulting mutants in order to select the ones that perform best for use at the industrial scale. At industrial scale, strict nutrient-controlled growth conditions are imposed to control the metabolic activity and growth...review 2023

Griffioen, Noah (author)The CONE-LCA framework is a promising framework that can be used to assess the impact of food items on human health and the environment. However, the nutrition-health assessment in the CONE-LCA framework quantifies the health impacts of food at the level of food items with the use of an indicator that is based on only few nutrients and otherwise...master thesis 2022

van Loosdrecht, Mark C.M. (author), Hao, Xiaodi (author), Wu, Yuanyuan (author)摘要： 好氧颗粒污泥技术具有占地面积小、能耗低、剩余污泥量少、抗冲击性强等优点，是<br/>一种可持续的污水处理技术。以北京某污水处理厂实际生活污水作为基质，在中试规模（有效容积<br/>为2.5 m3）反应器中进行好氧颗粒污泥培养，研究了颗粒污泥在低温条件下的稳定性。中试自夏季<br/>开始运行到次年春季结束，共计运行260 d。结果表明，采用我国实际低碳源市政污水可以培养出好<br/>氧颗粒污泥，污泥颗粒化程度可达94%，SVI5/SVI30为1.1 ~ 1.3。冬季低温会造成颗粒污泥的枝状结<br/>构增多、丝状菌生长，进而引起颗粒化比例略有下降，为80%~91%，污泥平均粒径降低，SVI5/SVI30升<br/>高至1.5 ~ 1.8。在冬季低温条件下，通过优化调控进水流量...journal article 2022

Becerra Perez, L.A. (author), Rincón, Luis E. (author), Posada Duque, J.A. (author)There is global pressure to make advanced biofuels profitable. For cellulosic ethanol, three aspects remain as bottlenecks: collection of feedstocks, pretreatment methods, and enzyme production. In this paper, the first aspect is investigated, by addressing the main challenges for the logistics of agricultural residues. A logistic supply...journal article 2022

(author)Energy-rich sludge can be obtained from primary clarifiers preceding biological reactors. Alternatively, the incoming wastewater can be sent to a very-high-loaded activated sludge system, i.e., a so-called A-stage. However, the effects of applying an A-stage instead of a primary clarifier, on the subsequent sludge digestion for long-term...journal article 2022

Toja Ortega, S. (author), Pronk, M. (author), de Kreuk, M.K. (author)High concentrations of particulate COD (pCOD) in the influent of aerobic granular sludge (AGS) systems are often associated to small granule diameter and a large fraction of flocculent sludge. At high particulate concentrations even granule stability and process performance might be compromised. However, pilot-or full-scale studies focusing...journal article 2021
