Proteinfoder kan produceres af kløvergræs ved hjælp af bioraffinering. Restprodukterne kan bruges til produktion af biogas og gødning

Biorefining of proteins from grass clover as an innovative solution to a truly sustainable organic production

To shape a common solution to challenges with low crop yields, proper protein supply and insufficient climate mitigation capacity, biorefining of protein feed from grassland crops for monogastric animals (including human) is introduced to the organic production system. Bio-refining using mechanical and natural fermentation techniques are compatible with the organic principles and standards. Crop yields from Danish field trials with alfalfa, clover and grass-clover mixtures demonstrate average yields around 12 tons dry matter per hectare yielding on average 700 kg extracted protein per hectare and 3000 to 6000 m3 methane per hectare. With these yields the profitability of biorefining of organic protein feed is calculated and shows a positive economic result, especially when used as wet-feed saving the cost for drying. But it should be noticed that economy is sensitive to changes in yields and prices

Hvorfor spilde tiden med kvindelig idrætsledelse?

Artiklen med undertitlen 'Kønskonstruktioner og ligestillingsmæssige tiltag i den frivillige idrætsledelse' har til formål at vise de kønskonstruktioner, der eksisterer i idrætsorganisationerne, og som har indflydelse på forudsætningerne for kvinders besiddelse af lederposter i organisationerne.Linnea Ytting: Why waste time on female sport leadership? About gender construction, gender equality in the voluntary sport organizationsThe sports organisations Danmarks Idræts- Forbund (DIF) and Danske Gymnastik- og Idrætsforeninger (DGI) have few women represented in their top leader positions. Both organisations have approximately 50% female membership and represent the entire Danish organised sport field. This is a sad fact, because women and men in many areas have different interests in sports. This article analyses some of the gender constructions of 6 young men and women in voluntary leadership, within chosen sports organisations. The purpose is to find the meaning of gender and describe how it is interpreted by the women and men in leading positions. The result of this research shows that many women are not interested in leading positions higher than club level. At the same time however, the structure of organisations are limiting, as to women wanting to achieve a higher voluntary leading position. Therefore it can be established that women must want the power, but the power must also want the women. In 2002 the political mainstreaming project was offered to sports organisations, introducing the gender problem on the political agenda. The political dimensions will therefore be included in the article, because the consequences may affect the sports organisation

Influence of the development stage of the plant biomass for protein yield in a green biorefinery.

The scarce availability of organic animal feed for monogastric animals is hindering the development of organic farming in many regions. A green biorefinery platform called OrganoFinery aims at producing organic protein-rich animal feed based on organically grown green biomass. The freshly harvested green biomass is separated into a solid fraction (press cake) and a liquid fraction (green juice). Subsequently, the green juice is inoculated with specific lactic acid bacteria which ferment the soluble sugars into lactic acid triggering a pH drop and thus, the precipitation of proteins. Last, proteins are extracted by centrifugation and the organic protein concentrate is suitable for feeding monogastric animals. Green perennial crops can be harvested several times during a season. In the present study, the impact of the development stage of the plant biomass, exemplified by red clover, at harvesting time for the protein extraction yield was assessed in order to develop a harvesting strategy. Red clover was harvested at different developmental stages i.e. early stem elongation, late stem elongation and heading. Right after harvest, the fresh biomass was processed to produce a protein concentrate as described above. The green juices presented higher concentration of soluble proteins and soluble sugars with increasing maturity. After 10 hours fermentation, the pH dropped from 5.9-6.0 to 3.9-4.0 in all green juice samples and the lactic acid concentration reached up to 20.6 g/L. The highest lactic acid concentration (20.6 g/L) was achieved for the late maturity stage and was 1.5 higher than in the early maturity stage. Differences due to the development stage were also observed in the recovery of proteins from the green juice into the protein concentrate. Indeed, the recovery of proteins from the green juice was between 70-80% of the content in the green juice and with the highest values obtained for the late maturity stage. The relevance of this study relies on the fact that the harvesting strategy is crucial in order to maximize the protein yield from green biomass and, to develop an economically viable green biorefinery platform to produce organic protein-rich feed for monogastric animals

Preoperative systemic inflammation predicts postoperative infectious complications in patients undergoing curative resection for colorectal cancer

The presence of systemic inflammation before surgery, as evidenced by the glasgow prognostic score (mGPS), predicts poor long-term survival in colorectal cancer. The aim was to examine the relationship between the preoperative mGPS and the development of postoperative complications in patients undergoing potentially curative resection for colorectal cancer. Patients (n=455) who underwent potentially curative resections between 2003 and 2007 were assessed consecutively, and details were recorded in a database. The majority of patients presented for elective surgery (85%) were over the age of 65 years (70%), were male (58%), were deprived (53%), and had TNM stage I/II disease (61%), had preoperative haemoglobin (56%), white cell count (87%) and mGPS 0 (58%) in the normal range. After surgery, 86 (19%) patients developed a postoperative complication; 70 (81%) of which were infectious complications. On multivariate analysis, peritoneal soiling (P<0.01), elevated preoperative white cell count (P<0.05) and mGPS (P<0.01) were independently associated with increased risk of developing a postoperative infection. In elective patients, only the mGPS (OR=1.75, 95% CI=1.17-2.63, P=0.007) was significantly associated with increased risk of developing a postoperative infection. Preoperative elevated mGPS predicts increased postoperative infectious complications in patients undergoing potentially curative resection for colorectal cancer

Identifying resistance genes in wheat against common bunt (Tilletia caries) by use of virulence pattern of the pathogen

455 wheat varieties and breeding lines were grown in the field,contaminated with 7 to 11 different races of common bunt. Based on the reaction of the lines to the different virulence races, it was possible to group the lines by differential varieties with known resistance genes, indicating that they may have one or two of the resistance genes Bt1, Bt2, Bt5, Bt7, Bt13, BtZ or Quebon-resistance. Based hereof, genetic markers will be developed using a genome-wide association study (GWAS)
