| establishing a risk-assessment process for release of genetically modified wine yeast into the environment. | the use and release of genetically modified organisms (gmos) is an issue of intense public concern and, in the case of food and beverages, products containing gmos or products thereof carry the risk of consumer rejection. the recent commercialization of 2 gm wine yeasts in the united states and canada has made research and development of risk assessments for gm microorganisms a priority. the purpose of this study was to take a first step in establishing a risk-assessment process for future use a ... | 2009 | 19898539 |
| dyadobacter soli sp. nov., a starch-degrading bacterium isolated from farm soil. | a gram-negative, non-motile, aerobic bacterial strain, designated mj20(t), was isolated from farm soil near daejeon (south korea) and was characterized taxonomically by using a polyphasic approach. comparative 16s rrna gene sequence analysis showed that strain mj20(t) belongs to the family cytophagaceae, class sphingobacteria, and was related most closely to dyadobacter fermentans dsm 18053(t) (98.9 % sequence similarity), dyadobacter beijingensis jcm 14200(t) (98.0 %) and dyadobacter ginsengiso ... | 2010 | 20008109 |
| complete genome sequence of dyadobacter fermentans type strain (ns114). | dyadobacter fermentans (chelius and triplett, 2000) is the type species of the genus dyadobacter. it is of phylogenetic interest because of its location in the cytophagaceae, a very diverse family within the order 'sphingobacteriales'. d. fermentans has a mainly respiratory metabolism, stains gram-negative, is non-motile and oxidase and catalase positive. it is characterized by the production of cell filaments in aging cultures, a flexirubin-like pigment and its ability to ferment glucose, which ... | 2009 | 21304649 |
