Gryzenhout's Lab

About the lab

Dr. Marieka Gryzenhout and Dr. Gert Marais are the P.I. of our lab.

Dr. Marieka Gryzenhout’s field of interest in Microbiology is Mycology. She specialises in fungi that affect plants, and this links to another field of specialisation, namely plant pathology.

Dr. Gert Marais is a senior lecturer and researcher; specialises in Mycological and Plant pathological research.

Pecan Health Research Group was established in collaboration with the South African Pecan Nut Producers Association (SAPPA). The research group is focusing on pecan diseases and improving the health of pecans in South Africa.

Cellulose is one of the most copious natural glucose biopolymers (linked by β-1,4-glycosidic linkages) that are derived from living organisms on the earth. Plants are the largest contributors of cellulose in the cellulose pool of the biosphere as plant cell walls contain cellulose in the lignocellulosic form. Cellulose is water-insoluble and therefore requires enzymatic actions for its degradation. However, the hydrolysis of lignocellulose into fermentable sugars, sugar acids, and phenolics is the reason why it is successfully exploited as substrates in industries. Microorganisms such as fungi, bacteria, and actinomycetes contribute largely to these lignocellulolytic activities by producing cellulases and other lignocellulolytic enzymes and therefore have been used extensively in cellulose-based industries ranging from food to biofuel production. Fungi have been a preferred source over the other microbes to produce lignocellulolytic enzymes owing to their ability to secrete extracellular cellulases in high quantities and are easily accessible. The chapter highlights the importance of fungal cellulases and related enzymes, their various industrial applications and emphasizes the importance of these hydrolytic enzymes to secure an eco-friendly environment, boost economics, and improve the livelihood of humans.
