Pseudolactal

The deacetylation of pentaacetylpseudolactal with barium hydroxide, in agreement with the similar reaction of diacetylpseudoglucal, does not lead to free pseudolactal but instead proceeds to isolactal (LIX) because of concurrent rearrangement.18,18... 

The constant presence of a proteolytic enzyme in industrial Bulgarian ferments, and the fact that the laboratory Bulgarian ferment studied by Bertrand, when cultivated in the presence of caldum carbonate, also develops its proteolytic properties to a pronounced degree, at one time led the writer to suppose here also the presence of the same bacterium which was undergoing biochemical variations under the influence of the conditions of the environment. Since then, a more thorough study has demonstrated that there is, in reality, a difference between Bulgarian ferment of Bertrand and B. pseudolactic contained in commerdal preparations, and that they must be regarded as two entirely distinct species. 

However, these discoveries do not at all affect the question as to the chemistry of the pharmaceutical lactic ferment. The true Bulgarian ferment, as we have seen, possesses proteols c properties whose manifestation requires certain conditions. Planted in the intestine, it exerts there its influence in the same manner as the lactic ferment influences the ripening of cheese, and this activity is also accentuated with time, the ferment acquiring a sort of enthusiasm for this new work. It must he noted, however, that in most of the tests made in hospitals, Lactobadllin has been used in lozenges, in powder, or even in milk which has been made to ferment by the aid of these substances, so that the universal reputation of Lactobadllin is due solely to the pseudolactic ferment which it contains.
