An aerobic Lactobacillus plantarum culture displayed growth stagnation during early growth. Transcriptome analysis revealed that resumption of growth after stagnation correlated with activation of CO2-producing pathways, suggesting that a limiting CO2 concentration induced the stagnation. Analogously, increasing the CO2 gas partial pressure during aerobic fermentation prevented the temporal growth stagnation.

Qila Energy: Ensuring quality and consistency in biogas across multiple AD plants - Case Study
Overview Qila Energy is a British engineering company who build Anaerobic Digestion (AD) plants throughout the British Isles. Their revolutionary two-stage process drastically reduces the time required to produce high quality biogas from varied feedstocks. Qila Energy is an industry leader of the UK’s farm-based AD industry producing high quality biogas that can be converted into electricity and injected into the National Grid. The Brief All Qila Energy plants have been constructed to be flexible and...
Biobased Economy opportunities for North-Netherlands
The three Northern provinces of the Netherlands could join forces to become a major producer and supplier of renewable resources for the regional production of ‘green’ chemicals, plastics and animal feed. This is one of the conclusions from research carried out by Wageningen University & Research, Greenlincs and the University of Groningen. Close collaboration with the German Weser-Ems area could boost the supply of ‘home-grown’ biomass raw materials. This would enable the North-Netherla...
Industrial Anaerobic Biological Fermentation - Case Study
The cooperation between the above mentioned innovative companies forces to impressive results. Hager & Elsässer planned the Aquatyx R2S reactor-technology which is installed in glass lined steel tanks from GLS Tanks International.AQUATYX is primarily for industrial anaerobic biological fermentation of highly polluted wastewater, as they are to also found for example in the paper industry.The two-step, into a tank mounted GLS system, characterized by a low footprint, high degradation rate and gas yield,...
Unlocking the potential of poultry manure
The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been referred to as a waste or an undesirable by-product of poultry and livestock production. In reality, manure is a valuable...
Case study - China Resources Gas Group Ltd
Anaerobic fermentation project with waste water in Qidong Jiangsu Province, China. The purification project was set up in order to connect the biogas to the city’s gas pipeline. The customer’s challenge Biogas upgrading: the Group aims to make use of what would ordinarily be a by-product – waste water. Gas is extracted from a water treatment process, using the contaminants found in waste water (energy-rich hydrocarbons – the same components that make up natural gas). The microbes used in...
