WBIJB is initiated by the Biotechnology Research Institute and published by UMS Press. It offers a platform for scientists to share scientific knowledge and discovery in the field of biotechnology. The scopes of this journal cover every aspect of biotechnology, including but not limited to biochemistry, molecular biology, bioprocesses, biosensors, genomics, transcriptomics, proteomics, and metabolomics. BIJB aims to provide readers around the globe with peer-reviewed research articles on a wide variety of biotechnology-related issues. The editors are committed to maintaining a high ethical standard, and do not tolerate plagiarism, duplicate publication, and other publication frauds and misconducts. While every effort has been taken to ensure compliance with the publication ethics, post-publication articles that are found to breach the BIJB copyright transfer agreement’s terms and conditions, or other publication ethics will be retracted from the journal. At least two peer reviewers are assigned to review each manuscript that is submitted to ensure the content has scientific merits and meets the required standard. New members will be added to the editorial board from time to time to include internationally recognized experts from different disciplines of biotechnology. At the same time, the publisher will continue to make the submission to this journal as user friendly as possible. Our vision is to have the BIJB indexed by international databases such as Scopus and Google Scholar within the next five years. In this inaugural issue, there are nine articles, and these are the highlights of these articles. Obeng et al. in their review paper describe the strategy to enhance the overall functionality of cellulases to produce higher product titer, through the supplementation of cellulases with biological complementation, and chemical additives in their review paper. In another review paper, Nabilah et al. documented several molecular techniques commonly used to assess and determine the genetic diversity of bamboo species. Teoh et al. analyze the characteristics of an Antarctic yeast, Glyciozyma antarctica. They report that G. antarctica PI12 is a bipolar budding and it forms a chain of cells at certain growth stages. They also describe the yeast hydrolytic enzymes. Chong et al. document the steviol glycosides separation from Stevia rebaudiana with several aqueous extraction techniques in their first paper, and rebaudioside A separation from Stevia rebaudiana using low polarity resin AB-8 in their second paper. iv | BIJB Vol. 1 (December, 2020), e-ISSN 2716-697X Budiman et al. reported on the reassessment of the catalytic and substrate specificity of Pk-FKBP35 using an alternative method of a protease-free assay. Sugumaran et al. in their paper attribute the antibiotic-resistant profile of Staphylococcus aureus and Escherichia coli isolated from recreational parks around Kota Kinabalu, Sabah. Simon et al. present the genetic diversity data of Sabah rice cultivars that they have analyzed using the random amplified polymorphic DNA (RAPD) technique. Their article provides insights into the genetic relationships and diversity of Sabah rice. Finally, Gilbert et al. describe the electrochemical sensor optimization for the detection of aluminium ion in drinking water. They indicated that the sensor holds great potentials for rapid on- site detection of heavy metal ions in the drinking water. As the editors of this inaugural issue, we would like to thank all contributors and reviewers as well as personnel at the Editorial Office of UMS Press.

However, the sugar yields achievable for canonical cellulases (i.e. endoglucanases, exoglucanases and β-glucosidases) have not been convincing in support of the highly acclaimed prospects and end-uses heralded. The persistent pursuit of the biochemical industry to obtain high quantities of useful chemicals from lignocellulosic biomass has resulted in the supplementation of cellulose-degrading enzymes with other biological complementation. Also, chemical additives (e.g. salts, surfactants and chelating agents) have been employed to enhance the stability and improve the binding and overall functionality of cellulases to increase product titre. Herein, we report the roadmap of cellulase-additive supplementations and the associated yield performances. Keywords: cellulases, hemicellulases, laccases, LPMOs, salts, surfactants INTRODUCTION Lignocellulose is an important cellulosic feedstock for producing bulk biochemicals and other value-added products due to its abundance, renewability and sustainability (Ramawat & Mérillon, 2015). The use of lignocellulosic biomass has received soaring attention within the last few decades because the ensuing products are believed to be a potential replacement of fossil fuels and fossil-based
