Alexxx [7]

Answer:

During the asexual reproduction, bacteria can divide simply by binary fission in which one bacteria first replicate its genetic material and the cell divide in two daughter cells which are identical to the parent cell.

Asexual reproduction does not allow genetic variation therefore to get genetic variation bacteria can use conjugation, transformation and transduction process.

In conjugation, bacteria gets extra genetic material from other bacteria through sex pills. In transduction the genetic material enters into the bacterial cell through the virus then bacteria incorporate this genetic material in its genome.

In transformation, bacteria takes up the extra genetic material from it's surrounding. Therefore conjugation, transduction, and transformation helps bacterial to gain variation like as in sexual reproduction.

Thermophilic anaerobic bacteria are highly insensitive to ethanol. Scientists demonstrate that one of their membrane proteins X
BARSIC [14]

Answer:

Since high ethanol is a major stress during ethanol fermentation, ethanol-tolerant yeast strains are highly desirable for ethanol production on an industrial scale. A technology called global transcriptional machinery engineering (gTME), which exploits a mutant SPT15 library that encodes the TATA-binding protein of Saccharomyces cerevisiae (Alper et al., 2006; Science 314: 1565-1568), appears to be a powerful tool. to create ethanol tolerant strains. However, the ability of the strains created to tolerate high ethanol content in rich media remains to be demonstrated. In this study, a similar strategy was used to obtain five strains with higher ethanol tolerance (ETS1-5) of S. cerevisiae. When comparing the global transcriptional profiles of two selected strains ETS2 and ETS3 with that of the control, 42 genes that were commonly regulated with a double change were identified. Of the 34 deletion mutants available in an inactivated gene library, 18 were sensitive to ethanol, suggesting that these genes were closely associated with tolerance to ethanol.

Explanation:

Eight of them were novel and most were functionally unknown. To establish a basis for future industrial applications, the iETS2 and iETS3 strains were created by integrating the SPT15 mutant alleles of ETS2 and ETS3 into the chromosomes, which also exhibited increased tolerance to ethanol and survival after ethanol shock in a rich medium. Fermentation with 20% glucose for 24 h in a bioreactor revealed that iETS2 and iETS3 grew better and produced approximately 25% more ethanol than a control strain. The performance and productivity of ethanol also improved substantially: 0.31 g / g and 2.6 g / L / h, respectively, for the control and 0.39 g / g and 3.2 g / L / h, respectively, for iETS2 and iETS3.

 Therefore, our study demonstrates the utility of gTME in generating strains with increased tolerance to ethanol that resulted in increased ethanol production. Strains with increased tolerance to other stresses such as heat, fermentation inhibitors, osmotic pressure, etc., can be further created using gTME.
