1.   As tomatoes ripen, an enzyme is produced which causes softening by breaking down the pectin in the cell walls.

2.   On application they literally digest smells by producing enzymes which attack the source of the odour, breaking it down for the bacteria to absorb.

3.   A microbial fuel cell contains bacteria that produce enzymes.

4.   Genetically altered microbes are also used to produce an enzyme widely used to turn milk into cheese.

5.   H. pyloris produces an enzyme, urease, which converts urea to ammonia and bicarbonate that neutralize the stomach acid and allow the organism to gain a foothold.

6.   He was particularly interested in how some bacteria come to produce an enzyme, beta-lactamase, that breaks down penicillin and similar drugs, making them ineffective.

7.   In ALD, a faulty gene is unable to produce the enzymes that clear away toxins that destroy nerve cells in the brain.

8.   Now a Pennsylvania pharmaceutical research company says it has patented a much cheaper method of producing the enzymes by using genes from bacteria enzymes.

9.   Second, studies of the rodents also suggest that calorie cutting somehow stimulates the animals to produce enzymes that can break down free radicals, Johnson said.
