Microalgal Fermentation
Background to Algal Fermentation
Microalgae initially gained attention for their ability to accumulate lipids that can be used for biodiesel production. However, with decades of research to improve the yields and with several failures of algal-biofuel
start-ups it became clear that this route was not economically viable at the time.
However, microalgae is a store of a variety of bioactive molecules such as pigments, polyunsaturated fatty acids, phycobiliproteins, and vitamins. These bioactives are high value molecules and can be used for food, cosmetic, and pharmaceutical applications which makes algae economically attractive.
Microalgae can also be used to treat waste water streams under mixotrophic cultivation and have recently gained great attention as bioremediation microbes, because of their potential to reduce potential while producing biomass that can be used to produce various chemicals. Algae are also being researched for gaseous fermentations to produce high value chemicals and also for upgradation of biogas. .

How Celignis Can Help
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. At Celignis we have particular expertise in the evaluation and optimisation of algae thorugh

Bacterial Fermentation
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.

Yeast and Fungal Fermentation
Yeast fermentation is one of the oldest fermentations and is used in everyday life to produce a variety of commodity products including bread, beer, wine,
cheese, and soy sauce. A few decades ago, yeast gained popularity as an industrial strain for biorefinery and biofuel applications.
At Celignis, we can use yeast and fungi for the production of: bioethanol, glycerol, single cell oils (SCOs), and emulsifiers, among other products.
