Some yeast and fungal strains are capable of producing lipids in a variety of substrates such as different types of
sugars, glycerol, etc. and have wide pH ranges. SCOs are edible oils if they are produced in clean substrates and can be converted to biofuels if industrial by-product streams
are used for their production.
How Celignis Can Help
Our team includes a number of fermentation experts who can work with you on the best process conditions for producing
SCOs.
We can also evaluate the suitability
of your process liquids for fermentation and, if necessary, can suggest
ways by which they can be detoxified in order to ensure that the sugars present in the hydrolysate are effectively utilised by the yeast and fungi.
There are 3 main types of processes for the fermentation of sugars to bioethanol: 1. Separate hydrolysis and fermentation (SHF); 2. Simultaneous saccharification and fermentation (SSF);
3. Simultaneous saccharification and co-fermentation (SSCF). SHF allows both enzymes and yeast operate at their optimum conditions, but is limited with
product inhibition to enzymes and feed inhibition to yeast. This is overcome in SSF and SSFC fermentation where the enzymatic product glucose
is consumed by yeast as it is produced. High solids loading fermentation with ethanol-tolerant yeast strains allows production of high concentrations of ethanol.
High-solids fermentation causes viscosity issues and hence suitable fermentation regimes and mixers should be designed in order to obtain maximum ethanol concentrations,
yields and productivity.
At Celignis we can use a variety of yeast types to produce bioethanol and can undertake and optimise each of these three main fermentation processes.
Bio-glycerol is gaining attention due to the consumer demand for non-petroleum derived products and also because of its potential to be a feedstock
for microbial chemicals production (e.g. 1,3 PDO).
We can design processes to produce glycerol in high glucose concentrations using osmo-tolerant yeasts.
The type, quality and quantity of emulsifier depends on microbial strain, carbon source, media components such as major and minor elements, temperature, pH etc.
It is important to optimise the process for product quality and quantity. This is only possible with the through understanding of microbial strain, its metabolism and needs.
Our experts can guide you through and optimise the process.

Bacteria are mainly used to produce organic acids and alcohols by anaerobic fermentation and enzymes by aerobic fermentation processes.
Very well-known natural fermenters are lactic acid bacteria (LAB) for lactic acid production and Bacillus species such as B. subtilis,
B. amyloliquefaciens, B. licheniformis, B. megaterium etc. for the production of enzymes, antibiotics, surfactins, and biopolymers.
Algal cultivation is complicated and requires optimisation to achieve high biomass yields. Algal biomass production depends on nutrient uptake and
other environmental conditions such as temperature, pH, salt concentration etc. It is important to select the strain based on the type of
production (open ponds, photobioreactors), feedstock and application. We have particular expertise in the evaluation and optimisation of algae thorugh
our Chief Innovation Officer, Lalitha, who is currently undertaking a Marie-Curie funded project at Celignis on this topic.
We are available to answer any questions you may have on how to get high value chemicals and biofuels from biomass through fermentation processes.

We detail the important contributions that Celignis can make in the 2022 topics
Today the Circular Bio-based Europe Joint Undertaking (CBE-JU) released their
annual work programme and budget for 2022. There is an indicative budget of 120 million Euros which
will fund a total of 12 topics, comprising 5 Research and Innovation Actions (RIAs), 1 Coordinating and Supporting Action (CSA), 4 Demonstration-Scale projects, and 2 Flagships.
Celignis is a partner in 3 ongoing CBE projects: UNRAVEL
and PERFECOAT are RIA (Research and Innovation Action) projects, whilst VAMOS is an Innovation Action project.
Additionally, Celignis was a partner in the BIOrescue RIA project which was completed in 2019.

Presentation and Exhibition Stand at IBioIC Annual Conference
We will be exhibiting at the event in Glasgow, UK, on June 6-7
The IBioIC Annual Conference makes a welcome return to Glasgow. The title of the event is "The Just Transition of Biotechnology - How sustainable development in industrial biotechnology can secure Scotland's path to Net Zero".
We are pleased to be exhibiting at the event, on June 6-7 at the Technology & Innovation Centre in Glasgow, UK. We look forward to discussing our range of analytical and bioprocess development services for bioeconomy stakeholders.
Our CIO Lalithawill also be giving a presentation at the event about our participation in EnXylaScope a collaborative research project funded by the the Horizon Europe programme.
Here you can download soft copies of the brochure,
It explains the background to the project and its targets for xylan extraction and modification
An introductory video to the EnXylaScope project (funded by Horizon Europe and technically led by Celignis) has been released. It has been prepared by our fellow consortium partner Loba and details the rationale for the project and the technical advances that the project will make, leading to an efficient and commercially-viable process for the extraction of xylan and its modification so that it can be incorporated into a range of consumer products.

It details the exciting progress already made in the project
The newsletter covers the project's activities in the search for xylan debranching enzymes (a WP with extensive involvement from Celignis) and on the extraction and modification of xylans for consumer products (a WP led by Celignis). Click here to view the newsletter.
