摘要:
The present invention addresses the problem of providing a new microorganism that is useful for efficiently decomposing oils and fats, and a use for said microorganism. According to screening results, a new Yarrowia lipolytica having a high capacity to assimilate free fatty acids was successfully obtained. Efficient decomposition of oils and fats is achieved by causing the Yarrowia lipolytica to act under conditions in which fatty acids that are hydrolysis products of oils or fats are present, or under conditions in which oils or fats are decomposed into fatty acids and glycerol.

The present invention provides a method of proliferating a microorganism capable of degrading a hard-to-degrade organic compound, comprising proliferating at least one microorganism capable of degrading a hard-to-degrade organic compound selected from the group consisting of Janibacter genus, Pseudomonas genus, Rhodococcus genus, Desulfomonile genus, Alcaligenes genus, Bacillus genus, Streptococcus genus, Acinetobacter genus, Achromobacter genus, Paracoccus genus, Rhodobacter genus, Rhodobacterium genus, Methylosinus genus, Mycobacterium genus, Nitrosomonas genus, Corynebacterium genus, and Methanotrophs, in a culture medium containing both a substance capable of inducing the degradation capability of the microorganism and Fe ions, under inorganic conditions. The present invention also provides a method of degrading a hard-to-degrade organic compound by using a microorganism capable of degrading the hard-to-degrade organic compound, comprising a step of controlling the degradation capability of the microorganism by adjusting the concentration of Fe ions in the culture medium.
摘要:
An apparatus includes a first mechanical component for cleaning parts by contacting the parts with a fluid, and a second mechanical component for biodegrading the organic matter removed from the parts. The first mechanical component is in communication with the second mechanical component so that the fluid recirculates between the first and second mechanical components. A method of washing parts including the steps of placing an article in a first chamber (20), circulating a washing liquid (82) from a second reservoir (80) to the first reservoir (20) to wash the surfaces of the article in contact with the liquid, passing the washing liquid (82) through a porous medium (38), draining the washing liquid from the first chamber (20) into the second chamber (80), removing organic matter in the washing liquid (82) and recirculating the washing liquid from the second chamber (80) to the first chamber (20), is also provided.
摘要:
Acrylamidase enzymes are provided which have acrylamidase activity at pH 4.0 which is at least 50 % of their acrylamidase activity at pH 7.0. Such enzymes can be produced by the novel microorganisms Rhodococcus strains NCIMB 40889 and NCIMB 40755. Such enzymes and microorganisms can be used for reducing free acrylamide in polyacrylamides which are produced at low pH and in particular cationic and substantially non-ionic polyacrylamides.
摘要:
The present invention is directed to a method for degrading an undesirable ether-based environmental contaminant by contacting the ether with a propane-oxidizing microorganism or with an isopropanol-oxidizing microorganism to convert the ether to innocuous compounds which are environmentally acceptable, including treating the ether-based contaminants in situ or removing them from the contaminated site for treatment in a bioreactor. Examples of ether-based compounds which can be degraded are tertiary butyl ethers of the type utilized as gasoline oxygenates, for example, methyl tert-butyl ether, ethyl tert-butyl ether, and methyl tert-amyl ether and also ether solvents, for example, tetrahydrofuran.
