abstract = {The aim of this study was the isolation and characterisation of the fungi and bacteria
during the composting process of sewage sludge under a semipermeable membrane system at
full scale, in order to find isolates with enzymatic activities of biotechnological interest. A total
of 40 fungi were isolated and enzymatically analysed. Fungal culture showed a predominance of
members of Ascomycota and Basidiomycota division and some representatives of Mucoromycotina
subdivision. Some noticeable fungi isolated during the mesophilic and thermophilic phase were
Aspergillus, Circinella, and Talaromyces. During the maturation phase, some lignin modifying enzyme
producers, like Purpureocillium, Thielavia, Bjerkandera, or Dichotomyces, were found. Within this group,
Thielavia and Bjerkandera showed high activity with production of laccases and peroxidases. In the
bacterial culturome, a total of 128 strains were selected and enzymatically analysed. Bacillales,
Actinomycetales, Pseudomonadales, and Lactobacillales were the orders most represented in
culture-bacteria. Bacillus pumilus, B. stratosphericus, B. safensis, and Pseudomonas formosensis were
the species most e cient in enzyme production, particularly peroxidases, polyphenol oxidases
ammonifying activity, and amylases. These results showed that sewage sludge composting piles
could represent a source of microorganisms which have adapted to adverse conditions.},
