Members of CIBIO Research Institute, led by Professor Maria Angeles Marcos Garcia, head of the Associated Unit to CSIC, have developed a method to raise the dipterans predator Sphaerophoria rueppellii. This insect is known for its efficiency and high specificity predatory sirphid being more suitable as biological control agent against agricultural pests from aphids in a Mediterranean climate crops. The use of this natural enemy for biological control of pests will reduce pesticide use in both agricultural crops and in urban gardens. Have been optimized environmental conditions for breeding, such as diet (both immature and adult stages) to ensure a higher reproductive potential and higher rates of survival. The group is looking for companies interested in acquiring the technology for commercial exploitation. Innovative aspects 1- The only species of industrially produced sirphid (Episyphus balteatus) does not effectively control aphid pests in Mediterranean cultures, this is why the selection of another species of sirphid to act as a viable alternative in the field Mediterranean was needed. The novelty of this specie is that and in most cases of biological control, using species that are commercially available, or not part of the fauna, in this case, we have managed to breed the species in field trials, proved to have the greatest potential for control. 2- This is the first time that this predator specie is bred in the laboratory and maintain continuously during successive generations breeding in significant amounts from individuals. 3- Due to the invention has been developed by a consolidated research group, it will be applied a Quality Control (under the rules of the International Organisation for Biological and Integrated Control), to ensure the viability and product quality

Cluster01 Cluster11a The increasing amount of dairy products challenge microbiologists and food engineers to develop solutions for combating bacterial threats, both to ensure product safety as well as increase shelf life. Bacteria such as Bacilli cause major economic damage, as they can withstand extreme temperatures and survive pasteurization. The ability of these bacteria to grow later on at low temperatures is one of the primary reasons for damaging product flavor and causing its spoilage. Here we propose a novel approach designed to eradicate any required specific bacterial species by the use of lysins; highly evolved hydrolytic enzymes produced by bacteriophages. These proteins are able to directly target peptidoglycan, the main component of the bacterial cell wall and spore shells, resulting in rapid cell lysis and death. While antibiotics often kill bacteria indiscriminately, lysins possess high species specificity, targeting only the desired strain, leaving the commensal bacteria undamaged. Moreover, lysins destroy the peptidoglycan directly, killing both growing and non-growing stationary bacteria. With the use of specific lysins, we are able to target and destroy any given bacterial strain from a mixture of many different bacteria. We demonstrate the use of this strategy and its efficiency, by killing specifically Bacillus subtilis grown in a mixture with other species using a purified lysin. This approach has been developed and utilized successfully in our laboratory for research purposes. The proposed strategy can be useful for many industrial processes, in which an elimination of a specific bacterium is required, leaving the desired bacteria unaffected. Furthermore, this method is not restricted to a single bacterium, as a cocktail of several lysins can be applied to eradicate various strains concurrently. This approach holds an enormous potential to revolutionize the way we fight bacteria in a safe and specific manner. Project ID : 23-2016-4288
