The markerless retrotransposition strategy enabled the rapid disruption of Ccel_2485 and Ccel_0137 genes in C. cellulolyticum, and their combination resulted in a strain that produced remarkably high yields of ethanol during polysaccharide and switchgrass fermentations.
The results were analysed by evaluating the numbers of strains that yielded Δ log10 CFU/mL) values of −1 (corresponding to 90% killing), −2 (99% killing), and −3 (99.9% killing) at 4, 6, 8, and 24 h compared to counts at 0 h.
The lower sensitivity of Rhodamine assay that is sometimes used to explain the discrepancy between the two approaches can be easily overruled in our case, by the fact that we were able to identify strains that yielded very clear halos with only traces of lipase activity in liquid cultures.
In the present study the Vg transgenes were expressed using a Gene-Switch driver strain that yields expression in only a subset of the fat-body tissues, so it remains possible that over-expression of the Vg genes using a driver with more extensive expression pattern in the fat body and/or other tissues might create a life span increase.
Engineering P. putida S12 for phenol production has yielded a strain that channels carbon fluxes to previously unfavourable routes to reconcile the drain on metabolites required for phenol production, while maintaining basal flux levels through central carbon metabolism.
Villa then embarked on a wretched run of two wins in 21 matches, plummeting down the table and stinking the place out with a strain of football that yielded an average of less than half a goal per Premier League game.
Co-culture model has also been used to predict the optimal relative cell ratio of each strain that yields simultaneous consumption of different sugar mixture with minimal fermentation time enabling improved productivity and less production cost (Hanly et al. 2012; Unrean and Khajeeram 2015).
The selected seasonal strains are therefore combined with an H1N1/A/PR/8/34 strain that grows at high yields in embryonated eggs [ 34].
Gorilla Glue is a particularly high yield strain that was bred by a ICMag.com thread user "Joesy Whales".
