Process for producing specific enzymes and proline by means of a new strain of anaerobic microorganism, a new inducible culture containing the said new strain and a process for the methanisation of protein residues by means of this culture

New anaerobic microorganism called Clostridium proteolyticum sp. nov. and a process for isolating it from sludge or similar materials. The use of this microorganism on gelatine or a similar material for the production, on the one hand, of proteases and collagenases and, on the other hand, of proline. The use of this microorganism in combination with Methanosarcina barkeri for the substantially complete degradation of complex proteins and in particular of gelatine, into methane and into carbonic anhydride; process for preparing the C. proteolyticum and M. barkeri co-culture used in the methanisation process and the culture thus obtained. NOUVEAU MICRO-ORGANISME ANAEROBIE DENOMME CLOSTRIDIUM PROTEOLYTICUM SP. NOV. ET SON PROCEDE D'ISOLEMENT A PARTIR DE BOUES D'EAUX RESIDUAIRES OU ANALOGUES.MISE EN OEUVRE DE CE MICRO-ORGANISME SUR DE LA GELATINE OU ANALOGUE POUR LA PRODUCTION DE PROTEASES ET DE COLLAGENASES, D'UNE PART, ET DE PROLINE, D'AUTRE PART.MISE EN OEUVRE DE CE MICRO-ORGANISME EN ASSOCIATION AVEC METHANOSARCINA BARKERI POUR LA DEGRADATION SENSIBLEMENT COMPLETE DES PROTEINES COMPLEXES ET NOTAMMENT DE GELATINE, EN METHANE ET EN ANHYDRIDE CARBONIQUE; PROCEDE DE PREPARATION DE LA COCULTURE DE C. PROTEOLYTICUM ET DE M. BARKERI MISE EN OEUVRE DANS LE PROCEDE DE METHANISATION ET CULTURE AINSI OBTENUE.
