Process for promotion of microbial consumption of waste water fats
| Details |
Inventors: Becker, Klaus;
Assignee: BTC Biotechnik International GmbH (Hamburg, DE)
Primary Examiner: Brown; Johnnie R.
Assistant Examiner: Crane; L. Eric
Attorney, Agent or Firm: Cushman, Darby & Cushman
The composition of stable microbial mixed biocenoses can be controlled by the addition of growth factors and/or inhibitory substances, optionally together with certain nutrients. It is possible in this manner to suppress, e.g. the undesirable formation of bulking sludge in sewage treatment plants or to improve the digestion of food or fodder containing biopolymers in the intestine or rumen. |

DETAILED DESCRIPTION What is claimed is: 1.
A process of purifying household or industrial establishment waste water pipes containing fatty waste water, which method comprises adding to the fatty waste water a growth factor which enhances the growth of bacteria contained in the waste water which break up or emulsify fat in an amount sufficient to effect the bacterial growth enhancement but insufficient to serve as a significant nutrient source for the bacteria.
2.
The process according to claim 1 wherein said growth factor comprises an amino acid and a carboxylic acid.
3.
The process according to claim 2 wherein said growth factor comprises a mixture of phenylalanine, arginine, asparaginic acid, oxalic acid, malic acid, malonic acid and propionic acid.
4.
The process according to claim 1 further comprising adding to the waste water a detergent or an agent that develops CO.
sub.
2.
5.
The process according to claim 1 further comprising adding to the waste water a detergent and an agent that develops CO.

Description:
The present invention relates to a method of controlling the composition of a stable microbial mixed biocenosis.
BACKGROUND OF THE INVENTION Almost all microbial conversions in nature take place by means of microbial mixed biocenoses (a mixed biocenosis is the symbiosis of different microorganisms).
Also, many industrial biological processes, e.
g.
, the biological purification of waste water or the production of sourdough are based on the metabolism of microbial mixed biocenoses.
It is known that mixed biocenoses develop over a very long period of time, in comparison to the generation time of the individual species, to very mature and stable biocenoses in which the organizational level, which can be expressed, for example, as the ratio of biomass to productivity, is high.
This is particularly true for biocenoses whose environmental conditions remain relative constant, as is the case in the intestine of warm blooded animals.
Stable biocenoses generally exhibit a plurality of control mechanisms which buffer changes of external conditions
