title: [Effect of biological activation on the evolution of microflora during composting of urban waste].
abstract: In two solid urban wastes piles, one treated with 7.5% of good bovine manure, the other used as a test, the evolution of the microflora has been studied, during the first period of biodegradation and at the end of the maturation process, in order to control if bioactivation can positively affect the biodegradation development. Actinomytcetes and fungi have been examined, and the following functional microbial groups: aerobic nitrogen fixing bacteria, ammonia bacteria, proteolytics, nitrosants, nitricants, aerobic cellulolytics, amilolytics, pectinolytics. During the process, no significant quantitative difference between the microflora of the two piles was found, except for aerobic cellulolytic, which were strongly superior in number in the end product from the bioactivated pile.
