About the book

Polysaccharides are universally present in almost all life forms. These natural biopolymers are produced by the Archaea, Bacteria (i.e., dextran, gellan and xanthan gums) and Eukarya (animals -corals, crab, prawn, shellfish, etc. -i.e., chitin, chondroitin, heparin and hyaluronan), plants (i.e., cellulose, guar gum, hemicelluloses and pectin), macroalgae (seaweeds i.e., agar-agar, alginate and carrageenan) and microalgae on sea and land. The aim of this book is to give an overview of the current scientific knowledge on polysaccharides of marine and terrestrial organisms. It will be a collection of articles about the production, characterisation and diversity of polysaccharides. Terrestrial polysaccharides, like their counterparts from marine organisms, have the potential to be valorised in various fields (agriculture, biomedical, biotechnology, cosmetic, environment, food, etc.). Thus, applications and modifications (polysaccharide derivatives as basic macromolecules for new polymers) of polysaccharides with their hybrids will also be addressed. This book will provide an opportunity to delineate novel mesmerising horizons in relation with polysaccharides.

Dr. Ir. Haïtham SGHAIER (TUNAC ISO 9001/17025/15189 Lead/Technical Assessor), is an Engineer in Biotechnology and Professor (Associate) of Radiation and Computational Microbiology at the National Center for Nuclear Sciences and Technology (CNSTN) in Tunisia. He was educated at Technical School (Kebili, Tunisia), INAT (Tunis, Tunisia) and ENIS (Sfax, Tunisia). He obtained a Master Degree from Kiryu Faculty of Engineering (Japan) and a Ph.D. following his research done at the Japan Atomic Energy Agency (JAEA, Japan). Being a glossophile, he won the 2002 best prize of Gunma University of the Third Speech Contest, in Japanese about peace, for foreign students. In 2007, he joined the CNSTN. He won the 2016 TWAS Young Arab Scientist (YAS) Prize. Basic research of Dr. Ir. Haïtham SGHAIER is related to the study of microbial resistomes, (oxidative) stress tolerance and interactions among prokaryotes/eukaryotes through computational biology and omics tools ( He has published on the evolution of ionizing-radiation-resistant prokaryotes (IRRP). In 2007, he draw attention to major discrepancy that has emerged between the ‘‘Desiccation Adaptation Hypothesis’’ and recent findings in computational biology, experimental research and terrestrial subsurface surveys. He proposed an alternative hypothesis, suggesting that desiccation tolerance could be a consequence of bacterial adaptation to ionizing radiation (Radiation Adaptation Hypothesis). Also, he has published on bioremediation issues, particularly on bioremediation of radioactive waste using IRRP. Currently, he is implicated in various ongoing projects: multi-omics analyses (;, databases (;; etc.) about IRRP, extremophiles, biotechnologically-relevant or disease-associated microbes, certification and accreditation of laboratories (ISO 11137, etc.).
