Exhibit 99.(a)(1)(B)

ELECTION FORM

I have received the Offer to Exchange dated January 21, 2015, this Election Form, the form of Stock Option Agreement (such form or an agreement with substantially similar terms being referred to herein as the “Agreement”) and the 2011 Equity Incentive Plan (the “2011 Plan”).

By completing, signing and delivering this Election Form, I hereby elect to exchange the following option grants to purchase Solazyme stock that I currently hold:

I understand that if I elect to exchange any particular option grant, I must exchange that option grant in its entirety. For each eligible option grant I have elected to exchange, Solazyme has informed me that I will receive, upon the terms and subject to the conditions in the Offer to Exchange and this Election Form (which together constitute the “offer”), a new stock option to purchase a smaller number of shares of Solazyme common stock, on a two-for-one basis at an exercise price equal to the last reported sale price per share of Solazyme common stock on the NASDAQ Global Select Market on the grant date of the new options, with the same rate of vesting, from the same vesting commencement date, as the corresponding eligible option, provided that any vesting that would have occurred prior to January 1, 2016 will cumulate and cliff vest on January 1, 2016. I understand that if I have not properly indicated my acceptance above or otherwise not properly completed this Election Form, Solazyme will be entitled, in its sole discretion, either to (a) request that I return a new Election Form indicating my election or (b) interpret my Election Form to be an election to exchange all option grants listed in the above table for which I have not checked “No.”

I hereby give up all ownership interest in the options that I elect to exchange, and I have been informed that they will become null and void on the date Solazyme accepts my options for exchange. I agree that I will have no further right or entitlement to purchase shares of Solazyme’s common stock under the eligible options accepted by Solazyme for exchange or have any other rights or entitlements under such options. I acknowledge that this election is entirely voluntary.

I acknowledge that upon the occurrence of any of the conditions set forth in Section 7 of the Offer to Exchange, Solazyme may terminate or amend the offer and postpone its acceptance and cancellation of any eligible options I elect for exchange. I acknowledge that the new stock options will be subject to the terms and conditions set forth in the 2011 Plan and the Agreement, which will constitute an agreement between Solazyme and me, and that the new stock options will be non-qualified stock options regardless of whether the option being exchanged was an incentive stock option or a non-qualified stock option. I further acknowledge that with respect to each new stock option, any vesting that would have occurred prior to January 1, 2016 will cumulate and cliff vest on January 1, 2016, even if the eligible options were fully vested on the date of the exchange. I acknowledge that as a result, I will be unable to exercise any portion of my new options prior to January 1, 2016, even if I leave Solazyme before January 1, 2016. I have reviewed the form of Agreement filed as an exhibit to the Schedule TO. Solazyme will send me a final Agreement (with all the blanks filled in) after the grant date. I further acknowledge that if I do not remain an eligible employee, I will not receive any new stock options or any other consideration for the options that I elect to exchange and that are accepted for exchange pursuant to the offer and that the existing options will remain outstanding with their current terms and exercise price.

INSTRUCTIONS FOR ELECTION FORM AND AGREEMENTS

FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

1. Delivery of Election Form. Solazyme, Inc. must receive your properly completed, signed and dated Election Form before the offer expires, which is currently scheduled for 9:00 p.m., U.S. Pacific Time, on February 18, 2015. Any Election Form received after that time will not be accepted. Delivery must be by one of the following methods:

You may confirm that your documents have been received by calling Idalina Chan at (650) 780-4777 or by sending an email to options-exchange@solazyme.com. Solazyme intends to confirm receipt of your Election Form within three business days of its arrival. If you do not receive confirmation of our receipt, it is your responsibility to ensure that we have properly received your election.

The method of delivery of any document is at your election and risk. If you choose to submit an Election Form, your election will be effective upon receipt. If hand delivery is not feasible, we recommend that you send it via electronic delivery or facsimile, and then follow up with a telephone call or email to confirm receipt by the deadline. If delivery is by mail, we recommend that you use registered mail with return receipt requested and properly insure your package. In all cases, you should allow sufficient time to ensure timely delivery.

Solazyme will not accept any alternative, conditional or contingent offers to exchange options. All eligible employees electing to exchange options, by execution of the Election Form, waive any right to receive any notice of the acceptance of their election to exchange, except as provided for in the Offer to Exchange.

2. Withdrawal of Election. Elections to exchange made pursuant to the offer may be withdrawn at any time prior to the expiration of the offer. To withdraw your tendered options, you must deliver a Notice of Withdrawal with the required information while you still have the right to withdraw the election. Withdrawal elections may not be rescinded and any eligible options withdrawn from the offer will thereafter be deemed not properly tendered for purposes of the offer. To re-elect to exchange options that you have withdrawn, you must again follow the procedures described in these Instructions to deliver a new Election Form prior to the expiration of the offer. In addition, although Solazyme expects to accept your validly tendered options promptly after the expiration of the offer, if Solazyme has not accepted and canceled your properly tendered eligible options by 9:00 p.m., U.S. Pacific Time, on February 18, 2015, you may withdraw your tendered options at any time after that date and until your tendered options have been accepted.

If you have any questions about the offer please call Paul Quinlan at (650) 780-4777 or Lori Urushima at (650) 780-4777, or send an e-mail with your question(s) to options-exchange@solazyme.com.

All questions as to the number of shares subject to options to be accepted for exchange and the number of new stock options to be granted, and any questions as to form of documents and the validity (including eligibility and time of receipt), form and acceptance of any options elected to be exchanged will be determined by Solazyme in its sole discretion, which determinations shall be final and binding on all interested persons. Solazyme reserves the right to reject any or all elections to exchange options that Solazyme determines not to be in appropriate form or the acceptance of which may, in the opinion of Solazyme’s counsel, be unlawful. Solazyme also reserves the right to waive any of the conditions of the offer and any defect or irregularity in any election to exchange options, and Solazyme’s interpretation of the terms of the offer (including these instructions) will be final and binding on all parties. No election to exchange options will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any defects or irregularities in connection with an election to exchange options must be cured within such time as Solazyme shall determine. Neither Solazyme nor any other person is or will be obligated to give notice of any defects or irregularities in the election to exchange options, and no person will incur any liability for failure to give any such notice.
