Biores Technol. HA isolated from rabbit manure at the thermophilic stage (HA-TRM), after the composting process (HA-CRM) and after the vermicomposting process (HA-VRM) show, for the strong and weak acidic sites (car-boxylic and phenolic), pKaap values shifted toward greater values in comparison with HA-S (5.5 and 9.8 respectively), indicating that the acidic sites are slightly weaker than the corresponding groups for HA-S. At the lowest pH measured (sites domains below 4), HA-CRM shows a developing peak (Figure 1b), indicating that very acidic sites could be present in the HA-like substances, and their content would be similar to HA-S. HA-TRM and HA-VRM present lower content of these classes of acidic sites, probably because, is the initial phase (thermophilic phase) for HA-TRM, and for HA-VRM may be due to the different biological transformation operated by vermicom-posting of the raw material. Each HA solution, with the corresponding blank solution, was titrated by triplicate and the reported data representing the average values.
