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.

Celignis to Sponsor and Present at Major Biochar Event
The event takes place on May 3rd at Carrick-on-Shannon
We are pleased to announce that, on May 3rd, Celignis will be presenting and exhibiting at the National Biochar and Carbon Products Conference 2023, which is taking place in Carrick-on-Shannon in County Leitrm, Ireland.
This conference is being organised under the auspices of the Interreg Northwest Europe-funded THREE C Project, entitled 'Creating and sustaining Charcoal value chains to promote a Circular Carbon economy in NWE Europe'.
The conference will highlight both Irish stakeholders who are currently working in the biochar and carbon products sector, but also partners from the THREE C project (covering Netherlands, Luxembourg, Germany, Belgium, France and Wales, as well as Ireland) who have interesting stories and products to share.

Click here to read about the different analysis packages that Celignis offers for the evaluation on biochars. These analyses cover properties relevant to a wide variety of applications, including soil amendment, carbon sequestration, bioenergy, and biomaterials.
For a short period we are offering two TGA analyses for the price of one!
To celebrate the arrival of our thermogravimetric (TGA) equipment, we are offering, for a limited time period, two TGA analyses for the price of one. Click here to read more about TGA analyses at Celignis and to see the various packages on offer.
To avail of this special offer please mention the code (TGA-AUGUST) in an email or when placing an order via the Celignis Database.
This 5 minute presentation was given at the recent IBioIC conference
Celignis recently exhibited at IBioiC's annual conference, held in Glasgow on June 6-7.
During that event Lalitha, Celignis's CIO, gave a short 5 minute presentation on the EnXylaScope collaborative EU research project that Celignis is involved in.
You can view the presentation below or here on YouTube.
