Abstract

1495029 Cultivating bacteria &c on paper waste C MUMFORD 23 June 1976 [1 April 1975] 13261/75 Heading C6F [Also in Division D2] A method of rendering vegetable and other parchmentized paper waste suitable for recycling involves shredding the paper waste, fermentatively degrading the shredded waste in an aqueous medium by cellulose-digesting micro-organisms or cellulolytic enzymes derived therefrom, recovering the weakened, digested paper from the treatment tank, as by a power conveyer, and collecting on a vacuum filter the protein-containing microbial mass produced. The micro-organisms employed may be naturally occurring strains from lakes, ponds, rivers, aquaria or soil, or mutants thereof. Sporocytophaga and Clostridium are among the genera (and species) particularly mentioned. The requisite nutrients for the cultivation may be added in the form of a specified proprietary agricultural fertilizer. The nitrogen requirements may be supplied by the propagation in the culture medium of nitrogen-fixing bacteria (Azotobacter). Where enzymes per se are to be employed, they may be secured by filtering a suspension of whole or crushed microbial cells, e.g. of Aspergillus niger. The usual enzyme is cellulase, #-1,4-glucan-4-glucan hydrolase. The treatment tank may be lined with polyethylene. The digested paper after treatment with sodium hypochlorite solution to kill off any micro-organisms, is added to other paper-making pulp in a conventional paper-making plant in a proportion of 10 or 20 wt. per cent.
