Mention has been already made of the discovery of lactic acid bacteria by Pasteur, of their importance in distilleries, and of their recent introduction into the latter in the form of pure cultures.
The first to isolate a pure lactic acid bacterium for the above purpose was, as has been said, F. Lafar. The species isolated and applied by him was Bacillus acidificans longissimus, Lafar, the cells of which are 2.5 to 25 µ long and about 1 µ broad.

Originally published in "The Independent" on December 23, 1922
THE French Government has announced the appropriation of 2,000,000 francs with which to celebrate properly the 100th anniversary of the birth of Louis Pasteur. The Government appropriation carries with it the statement that Pasteur stands as "The Symbol of French Science."
The anniversary date occurs on December 27, and if all who are beholden to Pasteur could be assembled in an evening of celebration, they would probably represent more diversified interests than, perhaps, would assemble to honor any other man of science.
The medical profession, for instance, is beholden to him for the first sterilized bandages, and the first sterilized instruments. Not only did he teach to medical men the theory of Sterilization, but he unfolded to them their first working knowledge of the great world of Microscopia that is invisible to the eye but works a mighty havoc in hospitals and among peoples where contagion may grow into epidemics.

Customized stem cells to help treat leukemia? |
| Two researchers at the Institut Pasteur and the National Center for Scientific Research working in the Institut Pasteur Macrophages and Development of Immunity Unit have just proved that hematopoietic stem cells, which produce blood cells throughout the life of each individual, are formed from the cells of the embryo’s aortic wall.

Cut out the preservatives |
| But after Louis Pasteur proved that it was the presence of bacteria that caused food to spoil, there is a tendency to consider all microorganisms harmful. Today, food industry uses nearly 6,000 chemicals to preserve foods. Highly attractive food packaging, taste-enhancers and convenience for the busy mothers are making our next generation dependent on packaged and processed which is taking them towards many health-related disorders.

What is Rabies? What Causes Rabies? |
| The term is derived from the Latin "rabies" meaning "madness". All human cases of rabies were fatal until a vaccine was developed in 1885 by Louis Pasteur and Émile Roux. Treatment after exposure, known as post-exposure prophylaxis (PEP), is highly successful. A recombinant vaccine called V-RG has been successfully used to prevent outbreaks of rabies in wildlife. Currently pre-exposure immunization has been used in both human and non-human populations. In many countries domesticated animals are required to be vaccinated.
