Yeast Are Microanisms In 1815 the French chemist Joseph-Louis Gay-Lsac ma some tertg observatns about yeast. Gay-Lsac was experimentg wh a method veloped by Nilas Appert, a nfectner and oker, for preventg perishable food om rottg. Gay-Lsac was terted g the method to mata grape juice wort an unfermented state for an fe time.

This also mak him the first person to postulate that the prciple of the nservatn of mass also applied chemil reactns: “We have to assume that there is a te balance or equatn between the elements of the pounds wh which we start and those obtaed at the end of the reactn” 1815, Gay-Lsac revised the balance of Lavoisier’s equatn, leadg to the rrect empiril equatn for fermentatn the late C20th, which is still known as the Gay-Lsac equatn today. Gay-Lsac was not the only scientist to ntue Lavoisier’s work, and 1858 Morz Trbe published Theorie r Fermentwirkungen, which was based on experimental evince and fally suggted that fermentatn self was a livg procs.
JOSEPH-LOUIS GAY-LSAC
Joseph-Louis Gay-Lsac, French chemist and physicist who pneered vtigatns to the behavur of gas, tablished new techniqu for analysis, and ma notable advanc applied chemistry. Gay-Lsac was the elst son of a provcial lawyer and royal official who lost his posn wh * gay lussac fermentation *
In 1810 Joseph-Louis Gay-Lsac disvered that sugars om grap fermented to we (CO2 and ethyl alhol). G., France, the term alhol by volume is often replaced by gre Gay-Lsac (thanks to the French chemist Joseph Louis Gay-Losac). The two sl differ slightly: Gay-Lsac the value of 15 °C (59 °F) for temperature (stead of 20 °C).
French chemist Joseph Louis Gay-Lsac proposed two fundamental laws of gas the early 19th century.
GAY-LSAC, JOSEPH LOUIS (1778–1850)
Joseph Gay-Lsac was a French chemist and physicist who did pneerg rearch to the behavr of gas. * gay lussac fermentation *
While one is generally attributed to a fellow untryman, the other is well known as Gay-Lsac’s law. Joseph Louis Gay-Lsac (1778–1850) grew up durg both the French and Chemil Revolutns.

Gay-Lsac’s own reer as a profsor of physics and chemistry began at the Éle Polytechnique. In 1804 Gay-Lsac ma several darg ascents of over 7, 000 meters above sea level hydrogen-filled balloons—a feat not equaled for another 50 years—that allowed him to vtigate other aspects of gas.
GAY-LSAC
In 1808 Gay-Lsac announced what was probably his sgle greatt achievement: om his own and others’ experiments he duced that gas at nstant temperature and prsure be simple numeril proportns by volume, and the rultg product or products—if gas—also bear a simple proportn by volume to the volum of the reactants.
This ncln subsequently beme known as Gay-Lsac’s law. Wh his fellow profsor at the Éle Polytechnique, Louis Jacqu Thénard, Gay-Lsac also participated early electrochemil rearch, vtigatg the elements disvered by s means. Featured image: Undated portra of Joseph Louis Gay-Lsac.
