• Kemal Yaylali
    Chief Technology Officer

Background

Kemal is a bioprocess engineer, and he has vast experience in microbial bioprocess development, strain management, bioreactor design, scale-up / scale-down, optimization of bioprocess control strategies, industrial biomanufacturing (including enzymes, proteins), commissioning, handovers and start-up processes. Kemal studied bioprocess engineering in Turkey and WUR (Netherlands).

In 2010 he established a biotech-oriented alcoholic beverage & commercial culture collection company, focusing on speciality strains for better products, and creating original culture collections. He then led the quadrivalent pertussis vaccine design and production project in Kocak Pharmaceuticals. Kemal worked for the Associated British Foods in commercial yeast production processes, and he was the head of production labs in the Tezkim citric acid plant.

Kemal is currently working at Celignis as our Chief Technology Offier. He plays important roles in our Bioprocess Development Services for clients and in the enhanced-scale testing of processes developed in EU research projects that we are collaborating in. He is primarily resident in our Celignis Bioprocess facility, located in Eastlink Business Park in Limerick, which allows for deployment of larger-scale reactors and processing technologies.



Expertise and Track-Record

Bioprocess Optimisation

Celignis recently launched a new bioprocess optimisation service, developed by Kemal, that reduces the time and financial costs compared with conventional optimisation approaches. This is done by combining theoretical modelling with experimental work and rapid analytical tools. The new Celignis Bioprocess Framework builds on the company's existing core strengths of biomass analysis, analytical method development, enzyme and microbial expertise, computational data, and data analysis.

Method Development

Over the years Celignis has greatly expanded the range of anaytical services it provides to our clients in the bioeconomy. Chris has been responsible for the development of many of these analysis methods and in the installation and maintenance of new equipment as the company has grown. This role has taken particular importance since Celignis relocated in 2018 to a premises 5 times larger than our previous lab. That move allowed us to accelerate our program of method development and the expansion of our range of equipment.

Biomass Combustion

To date most of the biomass that has been valorised has been processed via combustion technologies. The decision on which feedstocks are most suitable for a given combustion process is dependent on a number of key parameters relevant to the thermal processing of biomass. These include: calorific value, ash (content, composition, and melting temperature), chlorine content, elemental composition, and moisture content. Chris has the experience of analysing thousands of biomass samples for these properties, covering a wide variety of feedstocks.
