In many countries of the world, rice is a staple food. Small farmers, especially in South Asia and Africa, live from the cultivation of this important crop. However, their livelihood and food security are threatened by the plant disease bacterial blight. This is caused by the pathogen Xanthomonas oryzae pv. oryzae (Xoo). In India alone, the bacterium causes annual harvest losses worth around 3.6 billion dollars.

For many pollutants such as pesticides, the legislator has set threshold values. Below these limits, exposure is considered harmless. However, this does not seem to apply to many living organisms, including humans, as ecotoxicologists at the Helmholtz Centre for Environmental Research (UFZ) have now been able to show.

Wood is a diverse raw material. It is used as a building material and fuel, for furniture construction, but also for the production of biofuel and sustainable chemicals. But climate change is putting forests under increasing pressure as a source of raw materials. Coniferous woods such as spruce in particular have suffered from drought and heat in recent years, which has severely decimated the tree population in some regions of Germany. Such supply bottlenecks are a concern for the wood processing industry.

Just last spring, the European Investment Bank (EIB) put together a 400 million euro loan package to motivate private investors to give greater support to innovation in the bioeconomy and agriculture across Europe.

The genetic engineering ruling of the European Court of Justice in the summer of 2018 has political repercussions: the European Council, the EU's leading political body, has asked the EU Commission to clarify how "novel genomic techniques" are to be legally classified and regulated in the future. The results of this study are to be presented by April 2021 - including proposals and an impact assessment.

When factories and municipalities use water, it is usually polluted. Before it can be returned to the environment, it usually passes through a sewage treatment plant. However, sewage treatment plants represent a considerable cost factor, especially for smaller municipalities. The Ruhrverband is therefore testing a new process from the Netherlands in the Sauerland region that uses smart microbiological cleaning to significantly reduce space requirements, electricity consumption and operating costs.

Peppermint, lemon balm, wolf’s bane or chamomile are popular medicinal plants. They are used to soothe the symptoms of diseases in teas, but also in pharmaceuticals. But their cultivation is difficult. Even the smallest contamination by weeds can impair the effect of the medicinal plants. In the joint project Optimech, a team led by the University of Bonn is now investigating how medicinal plants can be cultivated in a way that is as soil-friendly as possible without having to use herbicides.

The mother-of-pearl inside a shell is not only beautiful to look at, it has also fascinated materials researchers for decades because of its exceptional toughness. It is considered one of the most resilient materials in the world. “Nacre is the prototypical supermaterial,” the researchers, including scientists from the Friedrich Alexander University Erlangen-Nuremberg (FAU), write.

The search for new active ingredients for the production of antibiotics is going strong. A promising source is the sea. Many microorganisms that have the potential to produce antibiotics settle here. With the marine phylum Planctomycetes, an international team of researchers has now identified a new source of active substances. Initial analyses suggest that these microorganisms, which have so far received little attention, are actually able to produce antibiotics.

Bamboo products are considered to be resource-efficient and sustainable. Cups, plates, cutlery, crockery or drinking straws are already made from the plant's woody stem axes or fibers and are available on the market. Especially in view of the forthcoming Europe-wide ban on disposable plastics, alternatives to conventional plastics are becoming more and more important. "From a health risk point of view, however, these products are not always suitable for use as tableware," warns Andreas Hensel, President of the Federal Institute for Risk Assessment (BfR).
