Biotechnology Laboratory

CETEC's biotechnology laboratory was created after more than 10 years of research into the study, production, and characterization of different biopolymers.

              The main objective is the use of micro-organism-based strategies to combat environmental problems.


The main lines of research of CETEC's Biotechnology laboratory are:

  • Biosynthesis of biodegradable biopolymers (PHAs)

  • Valorisation of agri-food industry waste as raw materials for biotechnological processes

  • Development of green biopolymer extraction methods

  • Bioremediation of nitrates, phosphates, nitrites, heavy metals from marine and brackish waters

CETEC has a complete laboratory for the biosynthesis of polyhydroxyalkanoates (PHAs), their extraction and purification, as well as the characterization of thermal, mechanical, rheological, optical, and barrier properties of PHAs.

We also have a pilot plant for scaling up biotechnological processes, up to a maximum fermentation capacity of 100L.

To find out more about PHAs

Polyhydroxyalkanoates are linear polyesters produced in nature by bacteria and other microorganisms under stress as an energy and carbon reserve.

They are considered strong candidates capable of significantly reducing the environmental impact in terms of consumption of non-renewable petroleum-based raw materials and generation of waste after use, as they can be produced from low economic value substrates, such as waste from the agri-food industry, and have similar physical characteristics to petroleum-based plastics.  

Among the advantages we found in this type of bioplastics are that they are 100% biodegradable in various habitats such as soil, sea, or stagnant water, both in aerobic and anaerobic conditions. They have naturally low gas and water permeability, making them ideal candidates for the packaging industry. They are also highly biocompatible and therefore have great potential in the biomedical sector.
