Of the 1882 patents on renewable energy published in 2007, more than half (1045) were related to biofuels. The rest included 555 patents on solar energy and 282 for wind. The Exchange Magazine website reports that biodiesel-related patents came in first in the list of biofuel patents, followed by ethanol and other alcohols, the far second. The United States, Germany and Japan were the top three countries with the most number of biofuel-related patents. About 57% of these patents are owned by corporate entities, while 11% are owned by academic institutions. The remaining 32% are “undesignated” (patent owner not listed in application). An increase in “agriculture biotechnology biofuel patents” (particularly, transgenic bioenergy crops) is expected to increase in the future. Likewise, the increase in the number of cellulosic biofuel patents is seen to rise, while traditional ethanol biofuel patents will continue to lag behind..

The Sugarcane Industry Union in Brazil, has plans to promote ethanol as a biofuel in the European Union (EU) by opening an “Ethanol Embassy” in Brussels (the EU capital). The embassy aims to “convince Europe's public opinion of the advantages of Brazilian ethanol over other forms of biofuel, in the light of heightened scepticism that do not differentiate between the many different fuels available”. The Biopact website says, that objectively, sugarcane ethanol, is a “sustainable biofuel”. Scientific studies (including life cycle assessment studies) have shown that sugarcane ethanol, in contrast to other bioethanol feedstocks, has a better net energy number and better in reducing greenhouse gas emissions. Sugarcane ethanol has been found to have a net energy value of 8 to10 (meaning 8 to 10 times energy can be obtained from the use of the fuel compared to the energy required to produce it), and reduces 80% of greenhouse gas emissions as a gasoline substitute. The ethanol embassy will closely track developments on biofuels in the EU, and “lobby and intervene when it thinks this is necessary”..

A University of Alabama (Huntsville) scientist in the United States, has mentioned that a shift in bioethanol feedstock from corn to cellulose-based trees and grasses, could help fight the rising incidence of “dead zones” in the Gulf of Mexico. “Dead zones” or “hypoxic zones” are regions of low oxygen in water bodies, and these areas are usually unfit for aquatic or marine life. Oxygen depletion in these zones, is said to be a consequence of algal blooms (triggered by  high nitrogen run-offs from fertilizer-intensive farmlands) which eventually die off and decay. The high demand for corn-based ethanol has caused record increases in corn cultivation in the United States, resulting in higher fertilizer use and run-offs with high nitrogen load, finding their way into the Gulf of Mexico. This has triggered massive algal blooms which eventually die off, settle, decay and cause the dead zones. Dr. Gopi Podila of the University of Alabama (Huntsville) Biological Sciences Department says, that a shift to cellulose ethanol (in the form of trees and grasses) could “take up some of that fertilizer and help alleviate the runoff problem before it hits the Mississippi Delta”. (The Mississippi River drains into the Gulf of Mexico). He adds that fast growing trees can grow on marginal lands and are cheaper to grow than corn. Dr. Podila’s current research (funded by the United States Department of Energy) is on genes that regulate growth in fast growing trees, particularly poplar and aspen. “If we can take a seven-year growth cycle and cut that down to six or five years, that's a tremendous gain”, he said..

Distiller’s Dried Grains (DDG) is a by-product in ethanol production after distillation of the fermentation broth. It is usually used as a component in animal feed. A recent study by scientists at the Department of Animal Sciences and Industry, Kansas State University (United States), have shown a postitive association between DDG in feed and the prevalence of E. coli O157 in cattle. (E. coli O157 is a toxin-producing strain of E. coli which can cause food-borne illnesses). Fecal samples of cattle fed with 25% DDG with 5% or higher stillage had higher counts of E. coli O157. Batch ruminal microbial studies and fecal microbial fermentation studies also point to the the close association between the presence of DDG in cattle feed and prevalence of E. coli O157. The researchers concluded that the results may have implications in food safety. The study is published in the journal, Applied and Environmental Microbiology (URL above)..
