Abstract
Slaughter waste normally contains considerable amounts of so-called stomach manure. Its biotechnical treatment rapidly decreases the waste problem. With the help of the method and device according to this invention stomach manure is first used as a biocatalyst in a process that produces mannitol. After that the lactic acid that at the same time farms into the slaughter waste is converted with the help of microbes into propionic acid or other useful compounds.

1-17 (canceled)
A method of utilizing intestinal bacteria, the method comprising the steps of:
- preparing a process liquid by adding a sugar selected from the group consisting of monosaccharides, disaccharides, and their polymers into manure selected from the group consisting of stomach manure of a slaughtered animal, manure produced by an animal, and refinery sludge;
- and
- increasing productivity or production levels of desired biotechnical products in the process liquid.
The method according to claim 1 further comprises the step of precipitating ammonium salts formed from the manure in the process liquid to fertilizers.
An apparatus for utilizing intestinal bacteria, said apparatus comprising:
- a reactor having a configuration capable of containing a process liquid including manure and a sugar, and adjusting a humidity percentage of the manure in the reactor;
- a container having a configuration capable of receiving a residue of the process liquid from the reactor, and adjusting a pH value and temperature of the residue suitable for production of propionic acid;
- and
- an inoculation fermentor having a dosing pump, wherein the inoculation fermentor having a configuration capable of inoculating microbial inoculums therein, and wherein the dosing pump has a configuration capable of pumping the microbial inoculums to the reactor.
