Fermentation. After the completion of the first L-DOS47 engineering batch and review of the production process, the second 500-1000 L engineering batch will commence. The 50 gram conjugate deliverable will require 25 grams of purified AFAIK2. Pending yields from the first Engineering batch this may require 2 × 500 L batches to be performed or a single batch performed at the required volume in a 1000 L fermentor. The fermentation will be performed using batch records revised from the first engineering batch to ensure the accepted protocol is followed; additional testing of samples or data collection can be recorded in laboratory notebooks.

Fermentation. The fermentation in the R&D laboratory will be performed at the 20 litres scale that is directly scalable to 300 litres owing to our extensive experience of E. coli processes. The purpose of the fermentation will be (1) to master the process developed by Xx. Xxxxx and (ii) to provide material for the down stream processing (DSP). Two fermentations have been programmed with the process of Xx Xxxxx. The protocol will be superstitiously reproduced in every details. A third one will be done if the parameterisation of the fed batch flow is more difficult than expected. As soon as the DSP has reproduced the process and the QC as established the necessary assays to qualify the protein, a fermentation will be performed according to our standard fermentation formula. It has been improved for years and has always been superior to what our sponsors have provided. During our meetings, we have expressed some concerns on the fermentation protocol used so far which appears to us to be outdated and not usefully complex, hence with some consistency issue. If our standard formula yields similar amount of best quality protein, we will propose to you to change for our simpler and more efficient protocol. If not, we will continue with the current method. As soon as the fermentation protocol is implemented in the laboratory, it will be transferred to the production unit. Two fermentations are planned to first confirm the scalability of the process second, to set the harvest parameters. So far the bacterial cells were harvested as a solid paste, this is impossible with our equipment at the 300 litres scale. The continuous centrifuge yields highly enriched cell suspension in buffer. Will this buffer exchange in the centrifuge be sufficient to go on with the process and how many cycles will be necessary to achieve sufficient medium removal. The cells harvested at this stage will be directly transferred to the R&D DSP laboratory for further processing and assessment of quality. The first step of full-scale liquid-liquid extraction and filtrabiity of the pro-APO Al fraction will be tested at this stage. The purchase of two large volume centrifuge will be necessary to run the process at the 300 litres scale. Two more 300 litres fermentations are planned for further consistency and to provide adequate material for the first full-scale purification, see annexed Xxxxx chart (Esperion total). At the completion of these assays, the fermentation process, harvest and extraction will be read...
Fermentation. Molasses containing 40 to 50% of total sugar would be weighed and diluted with clean as well as fresh water to the desired concentration. This would be achieved in a continuous diluter. The molasses-water mixture would have a specific gravity to the tune of 1.060 for pre-fermentation and specific gravity to the tune of 1.096 to 1.100 for the main fermentation process. The molasses with sp. gr. of 1.060 would be taken in to pre-fermenters and to it, ready compressed yeast would be added for further activation. As soon as the yeast becomes active in solution, the molasses-yeast slurry would be transferred to main fermenters for the process of conversion of sugars into alcohol. It takes about 24 to 30 hours to complete the fermentation reaction. Sugar in the molasses gets converted into ethyl alcohol and carbon dioxide through metabolic activities of the yeast. The fermentation efficiency observed, in above process, is generally to the tune of 85- 88% and ethyl alcohol concentration of @ 6% to 8% of volume in the fermented wash is obtained. This depends on the quality of molasses & its total sugar content.

Fermentation. Process Scale Up will verify that the fermentation conditions, growth and productivity of the organism, of Streptoverticullium cinnamoneus provided by Molichem are reproducible at AFI. This effort may be in part or wholly combined with Phase I Microbiology. Use or disclosure of the data contained on this sheet is subject to the restriction on the title page of this proposal.

Fermentation. Kosan expects to improve the now existing engineering space and possibly an additional 1000 sq. ft. to accommodate fermentation equipment for the production of research and/or GMP grade products. This improvement will require, but is not limited to, the installation of central steam generating equipment and associated plumbing, drainage plumbing and channels, waste disposal equipment, HVAC improvements and ducting, plumbed central gases, routing of electrical and water lines, alteration to the existing drop ceiling, and upgrade of flooring to epoxy resin.
Fermentation. The hoped-‐for 2 day fermentation process is taking up to 10 days. This is said to be caused by the low temperatures in the fermenting shed. Drying: Various drying solutions have been tried. They have a large cabinet dryer using diesel as fuel which is no longer in use. They have just received another electric cabinet dryer. The fuel efficiency of this drying solution is unknown but it is likely to require a high energy input per kg of product dried. There is no mechanical de-‐watering step prior to drying. Management challenges: The current supply strategy of NG Manioc is built up on a mixture of supply from the factories home-‐farm (50%) and production from larger farmers (>5ha) under contract. They plan to buy from small farmers, but have found this a challenge to date. The day-‐to-‐day management and business arrangements are opaque; and were not shared with the team on this short mission. Clearly, working capital is a problem. The operation was part of a larger company, but at some point has been spun off. The way forward: We will need to understand more about the operation of NG Manioc in three areas: Supply. How can they more efficiently manage root delivery to the factory and engage substantially more small-‐holder farmers who are beneficiaries of PADEF?
