Definitions

  • the present invention relates to alkaline protease obtained as an elaboration product of the growth of the microorganism Bacillus licheniformis A.T.C.C. No. 21424 in a nutrient medium, to a method of producing the alkaline protease, and to detergent compositions containing the protease.
  • Alkaline protease is a term used to describe a proteolytic enzyme which exhibits optimum activity in an alkaline medium.
  • Proteolytic enzymes of this nature are useful as an active ingredient in present day enzyme detergents and laundry presoak compositions. The enzyme is used for its ability to attack and remove the common soils and stains of clothing that have a significant protein content such as blood and grass stains.
  • alkaline protease A number of sources of alkaline protease are presently known. Some of the more important processes now in commercial use rely upon the fermentation of Bacillus subtilis and Bacillus licheniformis or some of the molds, such as the Aspergilli.
  • the enzyme provided by the present invention provides a basis for supplying protease to detergent formulations at a much lower cost per unit of enzyme activity.
  • the enzyme of this invention has a higher optimum pH for protoeolytic activity; viz., pH 9.0-1l.0 as compared with an optimum pH range of pH 8.5-9.5 for a commercially available enzyme prepared from Bacillus subtilis.
  • the enzyme of the present invention removes stains at least as well as, and in some instances, better than, the enzymes presently available on the market, and it has a greater solution stability in the pH range of 9.5-11.0.
  • the yield of alkaline protease obtained according to this invention is at least twice as high as is obtained from a hitherto high-yielding strain of Bacillus subtilis.
  • Bacillus licheniformis A.T.C.C. No. 21424 of this invention is characterized by the following reactions:
  • the media contained 0.2% of either sodium citrate, sodium acetate or sodium propionate.
  • the media contained 1% NaCl, 0.1% (N I-I HPO 0.05 KH PO 0.02% MgSO .7H O, 1.5% agar and 0.0008% phenol red.
  • the medium was adjusted to pH 7.0. At the end of the incubation period, growth was evaluated by changes in the color indicator from yellow to red.
  • B. licheniformic metabolizes all three organic salts while B. subtilis utilizes only citrate. Utilization of the anions by the organism released Na which in turn raised the pH of the medium and changed the indicator from yellow to red. Thus, the B. subtilis displayed red coloration on the citrate slants but no change on the acetate and propionate media. The other two organisms exhibited red coloration on all of the slants.
  • Control organisms used were B. subtilis A.T.C.C. No. 15841 and B. licheniformis A.T.C.C. NO. 12759. 'Both of these organisms as well as applicants B. licheniformz's A.T.C.C. No. 21424 were maintained on Trypticase Soy Agar slants (B.B.L. Labs) at 4 C. prior to use. All inoculations made in the tests were made directly from the slants.
  • the culture medium used consists of from 1% to 4% protein, from 1% to 12% glucose, and such mineral supplements as are necessary to insure proper growth of the microorganism.
  • Soybean meal is a preferred protein raw material.
  • Other protein substrates such as casein, Pharmamedia, a cottonseed-derived protein material, and Proflo, a partially defatted cooked cottonseed flour, both sold by Traders Protein Div. of Traders Oil Mill Co., Fort Worth, Tex.
  • the mineral salts found useful with the preferred culture medium for use according to this invention include MnCl MgCl CaCO CaCl NaH2PO4, Na HPO and ZnCl Maximum enzyme production is obtained when the medium is initially buffered at pH- 7.6. Yields became progressively less as the pH is varied in either direction from this value, and at pH values below 7 or above 8, the yield becomes unacceptably low.
  • a calcium salt such as calcium acetate
  • Insoluble calcium phosphates are formed which, in turn, absorb a gel-like material and both are removed by the centrifugation.
  • the clear supernatant liquid in this case, contains 98% of the total enzymatic activity in the culture medium.
  • the enzyme may be recovered from solution by adding one-third volume of acetone at 2 C. to the clear supernatant. The resulting precipitate is removed by centrifugation and discarded. Additional acetone is added until 75% saturation of the fluid is obtained. The suspension is stored at 20 C. until precipitation is complete (about three hours). The precipitate is collected and dried to yield a powder.
  • the alkaline protease of the present invention is used as an active ingredient in enzyme detergent compositions.
  • the enzyme may be in powder or liquid form, and may be diluted with other ingredients. It is customary to dilute enzyme powder, as obtained by recovery from fermentation processes, with a compatable diluent such as sodium sulfate.
  • Alkaline protease of this invention is used in an enzyme detergent composition at a level varying from 0.02% to 0.1% of the powder. When the enzyme powder is diluted approximately fivefold with sodium sulfate, it has an activity of about 1300 proteolytic units/ mg.
