Methanogens and methylotrophs,The Italian physicist Volta must be credited for observation that the bubbles arising at the surface of Lago Maggiore were inflammable (1776). Thirty years later, this combustible air was identified as methane (CH.), whose microbial origin was established only in 1868.

Transcription. RNA polymerase,At the end of the 1950s Hoagland and Zamecnik had succeeded in obtaining an . protein synthesis from ribosomes and crude acellular extracts. Ribosomes cannot by themselves achieve a specific protein synthesis and require an information originating in last analysis in the genes.

Biosynthesis of lipids, produces .-butyrate and .-caproate. From this organism, Barker and Stadtman obtained cell-free extracts which could carry the reactions leading to the C4 and C6 acids. Ethanol is oxidized to acetic acid in two steps, respectively, catalyzed by alcohol dehydrogenase and an acetaldehyde dehydrogenase depending on the presence of coenzyme A:

The outer membrane of Gram-negative bacteria and the cytoplasmic membrane,e constructed an additional structure that surrounds the cell outside the cytoplasmic membrane. An example of this are Gram-negative bacteria, such as ., which surround themselves with a second outer membrane which functions as an effective barrier.

Negative regulation,or the inducer and for the operator have been determined; the repressor extracted from an .. strain has lost its affinity for IPTG; the operator is a DNA segment which specifically binds the repressor; finally the inducer displaces the repressor from its complex with the operator. We shall now describe briefly these experiments.
