The operation of cell disruption is indispensable but cost much in microalgae industry. To be simplified, two different reaction mechanisms await in the cell to respond to moderated or stressed environment. The physical and chemical changes of enzyme and turgor pressure of cell in this conversion play an important role in the enhancement of biomass and metabolites. Repeated turgor pressure (based on the structure and mechanics of cell wall) and converted enzyme system (based on photosynthesis) were used to loosen cell wall and then repeated cultivation of Haematococcus pluvialis for astaxanthin extraction was proposed. There was no significant difference of extraction yield between the broken cell (94.75 3.13%) and non-broken cell (92.32 3.24%) treated by the repeated cultivation. Meanwhile, fed-batch culture according to the relationship among pH and nutrient concentration was used to enhance the biomass of Haematococcus pluvialis with the dry cell weight of 1.63 0.07 g/L.
Fibrinolytic proteases are enzymes that degrade fibrin; these enzymes are a promising alternative for thrombolytic therapy, and microorganisms produce them. The aim of this study was to evaluate the optimum conditions for the integrated production and purification of fibrinolytic protease from Bacillus sp. UFPEDA 485. Extractive fermentation was carried out in a culture medium containing soybean flour and by adding polyethylene glycol (PEG) and Na2SO4 according to a 2(3) experimental design. In all assays, the enzyme preferentially partitioned to the bottom phase (K < 1), with an optimum activity of 835 U ml(-1) in the bottom phase (salt-rich phase). The best conditions for extractive fermentation were obtained with 18 % PEG 8000 and 13 % Na2SO4. Characterization showed that it is a metalloprotease, as a strong inhibition-residual activity of 3.13 %-occurred in the presence of ethylenediaminetetraacetic acid. It was also observed that enzymatic activity was stimulated in the presence of ions: CaCl2 (440 %), MgCl2 (440 %), FeSO4 (268 %), and KCl (268 %). The obtained results indicate that the use of a low-cost substrate and the integration of fermentation with an aqueous two-phase system extraction may be an interesting alternative for the production of fibrinolytic protease.
(1) IRM 3.13.2.1(7) - Added paragraph indicating: This IRM includes information and instructions to work BMF entity cases and can't cover all situations, so judgment is needed to work the case. Contact your Manager or Lead tax examiner to determine if your decision is valid. You should request an IRM change to add instructions if you encounter repeated problems or issues which are not currently in the IRM. IPU 23U0008 issued 01-03-2023.
(89) IRM 3.13.2.17.3(8)(A, B, C, D & E) - Removed Form 941-SS, Form 941-PR, Form 943-PR, Form 944-PR, and Form 944-SS, here and throughout the IRM, as they are discontinued forms after 2023. Added Form 941 (SP) and 943(SP).
The document/return must be signed by the taxpayer or authorized representative for IRS to update any information (name, address, etc.). Returns, forms, correspondence and direction from the taxpayer regarding their account will be accepted prima facie, see IRM 3.13.2.2(10), BMF Entity - General.
Exercise caution when changing the name on an EIN. Often taxpayers request a name change when the issue is really a change in organizational structure.
For example, Maple Leaf LLC requesting a change to Maple Branch Inc. This is more than a name change; it is a change in structure that requires documentation. See IRM 3.13.2.10.9(1), Change in Ownership or Change in Officers, Partners, or Members, and IRM 3.13.2.10.18, State Reorganization/Conversion.
When the organization name contains the words "Fund" or "Foundation" , corporate name control rules apply. See IRM 3.13.12, Campus Document Services - Exempt Organization Account Numbers.
For example: Kathryn Osprey Memorial Foundation.
Signatures on Form 8822/ Form 8822-B and requests for address changes will be accepted prima facie. See IRM 3.13.2.2(10), BMF Entity - General. If there is no contradicting evidence to dispute the authority of that person, the signature must be accepted. This policy applies to signatures accompanied by titles such as owner, president, etc. This authority does not apply to third party requests. A Form 2848 is required for a third party not listed on CC CFINK.
If Part I of Form 8822 is complete and received in a Business Master File (BMF) site, it will be processed. See IRM 3.13.5.52, Form 8822, IMF Change of Address Request. Process Form 8822 per chart below.
Ensure the person signing Form 8822-B is authorized to represent the entity shown in Item 4a. See IRM 3.13.2.3, Entity Types - Name Controls, Filing Requirement Codes (FRCs), and Authorized Representatives, for definitions of an authorized representative.

Form 945 valid range is 1. Form 945 FR is valid with all other filing requirements. If Entity can determine by taxpayer contact or the taxpayer indicates that they are liable to file Form 945 (for example, liable for non-payroll income tax withholding on backup withholding or withholding for pensions, annuities, IRAs, Indian gaming and gambling winnings) establish Form 945 FRC 01. Otherwise, DO NOT establish a 945 FRC. Form 1042 valid ranges are 0, 1 or 8. Form 1042 FR is valid with all other filing requirements. See Figure 3.13.2-4 for the CC ESIGN format.
The TIN will be validated with CC ENREQ and EOREQ. For a TC 000 to be input, a TC 000 intend indicator of 1 must be input in space 20 with the CCs ENREQ or EOREQ. If the TIN is not on the Master File when the indicator is input it will allow the TC 000 to post. If the TIN is known to be on the Master File and no TC 000 intend indicator is input the appropriate TC (those other than TC 000) can be input. See Figure 3.13.2-6
Transaction Code 014: This generated transaction indicates a change has been made to the mailing address fields. All transactions containing an address change will have the requester's name, title, and phone number if present in the Remarks field of the transaction. If you are unable to determine the name and/or title, enter "SIGNATURE ILLEGIBLE" and the requester's phone number (if available). See Figure 3.13.2-9.
Transaction Code 041: This input transaction code changes an SSN or name of an account to the invalid portion of the BMF. This transaction must be input to a BMF invalid SSN account. See Figure 3.13.2-13.
Transaction Codes 090 through 097: are used when processing Form 2553, Election by a Small Business Corporation. See IRM 3.13.2.23, Form 2553, Election by a Small Business Corporation, and Related Transactions/CPs.
Transaction Code 053: identifies a change to accounting period because of an approved Form 1128, Application to Adopt, Change, or Retain a Tax Year. See IRM 3.13.2.21, Form 1128 - Application to Adopt, Change or Retain a Tax Year.
Transaction Code 055: identifies an approved FYM under IRC Section 444 on Form 8716, Election To Have a Tax Year Other Than a Required Tax Year. See IRM 3.13.2.22, Form 8716 - Election to Have a Tax Year Other Than a Required Tax Year.
BMF Entity primarily uses IRSNs when processing Estate and Gift (E&G) returns, Form 706 and Form 709 families, and Form 8288, U.S. Withholding Tax Return for Disposition by Foreign Persons of U.S. Real Property Interests. IRSNs are also used when processing INVALID SSN TRANSCRIPTS, see IRM 3.13.2.20.1, Transcripts. Form 9956, Request for Temporary SSN, is used by other areas to request an IRSN from Entity.
Edit Form 8161/voucher/routing slip by circling out incorrect information such as name control, MFT, tax period and/or EIN. Edit correct information and underline in appropriate field(s) of Form 8161. If the form is processable, underline the Tax Period at the top of Form 8161 and edit MFT in Field (14) of Form 8161. If payment is Unprocessable write "unprocessable" in Field (14) of Form 8161. Enter audit trail as shown in IRM 3.13.2.8.2, Processing BMF Returns, with TE number and date.
Edit Form 8161/voucher/routing slip for ERS return by circling out incorrect information such as name control and/or EIN. Write correct information and underline in appropriate field of Form 8161. If return is unprocessable, enter such in Field 7 of Form 8161. Edit in Tax Period and MFT or unprocessable in Field (14) of Form 8161. Enter audit trail as shown in IRM 3.13.2.8.2(16), Processing BMF Returns, with TE number and date.
If the Notice Code (NTC-CD>) on ENMOD is A or B, this indicates that a new EIN was assigned from a return/payment and a notice was sent to the taxpayer requesting completion of a Form SS-4 (See Figure 3.13.2-14).
Entities that are incorporated under state law are considered corporations for Federal Tax purposes. A corporation must file one of the Forms 1120, unless it is an exempt organization. See Figure 3.13.2-21. Exempt organizations that are incorporated file one of the Forms 990 series returns.
The corporation must make a Subchapter S-election on a timely filed Form 2553. If Form 2553 is attached to Form 1120-S and the return has yet to be numbered, detach and process Form 2553. See IRM 3.13.2.23, Form 2553, Election by a Small Business Corporation, and Related Transactions/CPs.
If a valid paper Form 1120-S is received in Entity because the current FRC on IDRS is 1120-01, check for an unreversed TC 090. If found, delete the 1120-01 FRC and release the return. The return will now read the DLN of the TC 090, post and generate an 1120-02 FRC. If TC 090 is not posted, route return to originator explaining taxpayer does not have a valid Subchapter S-election. See IRM 3.13.2.23 (3), Form 2553, Election by a Small Business Corporation, and Related Transactions/CPs. This will not work for MeF returns as MeF returns must pass a FRC validity check. See IRM 3.13.2.10.19, Updating Account Information for Modernized e-File (MeF), for resolving electronic returns with a FRC problem.
