1.   During fermentation, hydrogen gas production is used by bacteria to allow oxidation of reduced cofactors.

2.   These bacteria use molecular hydrogen as well as other electron donors, for the dissimilatory reduction of sulphate to sulphide.

3.   Bacteria have used such survival strategies for millions of years, but now things are different.

4.   Heal doubts whether it could be any of the known chemical messengers, or pheromones, that bacteria use.

5.   Scientists have cloned the genes that the bacteria use to make these drugs.

6.   Since the bacteria are better competitors than the plants, the plants go hungry while the bacteria use the nitrogen.

7.   So the bacteria use a membrane of elastic material to keep the crystals apart.

8.   The bacteria use their new tails to race to the cell wall, where they break out into a neighboring cell to repeat the cycle.

9.   The cells comply and the bacteria use the fucose to make more of the signal, setting up a reciprocal relationship.

10.   In a discovery that could lead to powerful new vaccines and antibiotics, researchers have isolated a key gene that bacteria use to launch killer infections.
