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.

The risks of spreading slurry after first silage cut
Livestock farmers spreading slurry onto fields after first-cut grass silage face heightened risks of contamination after this year’s early start to the season, a silage specialist is warning, especially if following the current trend to more frequent silage cutting.The risks of spreading slurry after first silage cut According to Ecosyl silage expert, Darran Ward, spreading slurry after first-cut always poses a risk – because of the challenge of achieving the 10-week interval typically recommended...
How to produce good quality silage
We all know the benefits of good silage. But are we really all doing everything we can to produce good quality silage? If you want to help protect your farm business against ups and downs in milk or meat prices, or feed costs, there’s a straightforward approach: maximise the amount of milk or meat produced from home-grown forage. It is arguably one of a livestock farm’s biggest assets. Producing quality silage Grass harvest will be here before we know it. So it makes sense to get the most from it....

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,...
