To replace chemical synthesis with environmentally friendly processes, CEB will identify, develop and test biological catalysts (enzymes) from extremophiles. The centre, located at the University's School of Natural Sciences, has received PS5m of EU funding through the Welsh Government and will boost the region's capacity to work with industry and to further develop this rapidlyemerging sector.

Extremophiles are organisms which can survive in extreme environmental conditions of temperature, pressure, pH, high metal and salt concentration, radiation, etc.
Among the topics are sucrose-transforming enzymes: hydrolysis and isomerization, pectinases and their biotechnological applications, the role of intrinsic and supplemented enzymes in brewing and beer properties, microbial linamerase in cassava fermentation, and extremophiles as potential resources for food processing enzymes.
Over the last years, extremophiles with its different categories, thermophiles (high temperature), acidophiles (low pH), alkaliphiles (high pH), halophiles (high salinity), and psychrophiles (low temperature) [7], have fascinated researchers in many fields, due to their ability to withstand and function under extreme conditions.

Another interesting thing about oceans is the extremophiles, which have commercial and medical applications, including treatment of cancer.
On a microbial level, Lassen's hot springs are under close scrutiny by virologists and astrobiologists because of recently discovered bacteria and high-heat-loving microorganisms called extremophiles. How these life forms thrive in such intense conditions may offer insight into what types of life we might find on other planets.
