Repeated-batch food waste fermentation for n-caproate production with reduced hydroxide use and no external electron donor addition

Fed-batch food waste fermentation was done without pH control for n-caproate production in an open microbiome. Acidification was steered towards lactate and, subsequently, chain elongation to n-butyrate and n-caproate was observed. Lactate was a key electron donor and its consumption during chain elongation helped to reduce the chemicals use for pH control

Raw experimental data from paper "Activated Carbon mixed with marine sediment suits as bioanode material for Spartina anglica Sediment/Plant Microbial Fuel Cell: plant growth, electricity generation and spatial microbial community diversity"

The main objective of this study was to investigate the suitability of mixture of activated carbon and marine sediment as a bioanode in a plant-MFC system with Spartina anglica. Here it was studied how different mixtures of the activated carbon (AC) and the marine sediment (MS) as an anode material affected the plant vitality, electricity generation and spatial microbial community. Four different anode compositions were used to fill the anode compartments (650ml). Plant-MFC 1 and Plant-MFC 2, this duplicate was named as AC100, were filled with 100% activated carbon (AC); Plant-MFC 3 and Plant-MFC 4, this duplicate was named as MS100, were only filled with marine sediment; Plant-MFC 5 and Plant-MFC 6, this duplicate was named as AC67, were filled with a mixture of 67 % AC and 33% marine sediment; and Plant-MFC 7 and Plant-MFC 8, this duplicate was named as AC33, were filled with a mixture of 33% AC and 67% marine sediment

Data underlying the research A multi-method approach to circular strategy design

This dataset contains a material flow analysis (MFA) for PET plastic in Jakarta, Indonesia. It supports the analysis of policy futures for plastic waste management in Indonesia by considering the flows of material across urban waste management systems. The data was collected by fieldwork in Jakarta and collated into an MFA for PET plastic (t/a), a material flow scheme showing main routes and data substantiation showing calculations performed in creation of the MFAs. The interview questions used to collect this data are also contained in this file. </p

Ivium Raw data of Charging and Discharging experiment for article "Marine sediment mixed with activated carbon allows electricity production and storage from internal and external energy sources: a new rechargeable bio-battery with bi-directional electron transfer properties"

In this study, we investigated the potential of marine sediment and activated carbon to generate and store electricity. Both internal and external energy supply was validated for storage behavior. Four types of anode electrode compositions were investigated. Two were mixture of different volumes of activated carbon (AC) and mixed with Dutch Eastern Scheldt marine sediment (67% AC, 33% AC) and the others were 100% AC or 100% marine sediment based. Each composition was duplicated. Operating these BES’s under MFC mode with solely marine sediment as the anode electron donor resulted in the creation of a bio-battery system. The recharge time of such bio-battery does depend on the fuel content and its usage

Data underlying the publication: nZVI impacts substrate conversion and microbiome composition in lactate-based chain elongation from D- and L-lactate substrates

Medium-chain carboxylates (MCC) derived from biomass biorefining are attractive biochemicals to uncouple the production of a wide array of products from the use of non-renewable sources. Biological conversion of biomass-derived lactate during secondary fermentation can be steered to produce a variety of MCC through chain elongation. We explored the effects of zero-valent iron nanoparticles (nZVI) and lactate enantiomers on substrate consumption, product formation and microbiome composition in batch lactate-based chain elongation
