Report of hypoxic-anoxic dead zone in Johor Straits

Harmful algal bloom (HAB) leading to fish kills is no longer a rare occurrence in Malaysian waters, particularly the strategically and economically important Johor Straits. It is a national border between Malaysia and Singapore, and the coastal areas of both sides are dotted with aquaculture, industrial and residential activities.

In our recent paper published in July 2020, in collaboration with the Institute of Ocean and Earth Sciences (IOES), University of Malaya, we discovered the presence a hypoxic-anoxic “dead zone” (low dissolved oxygen) in the inner Johor Straits, spanning an area of more than 10 km square. We also observed seasonal blooms of diatoms Skeletonema, Chaetoceros, Rhizosolenia and Thalassiosira. Diatoms are important for the marine ecosystems. However high nutrient concentration (particularly from human activities) in the water may lead to excessive proliferation of diatoms, inducing the hypoxic-anoxic conditions. Read more here.

This project was funded by the Transdisciplinary Research Grant Scheme (TRGS), Ministry of Education Malaysia.

Vacancy: Postdoctoral Researcher “Conversion of CO2 to CH4 by Methanogenic Microbes for Use in Valued-added Geologic Carbon Capture and Sequestration”

Update: The position has been filled. Thank you for all the interests.

Conversion of CO2 to CH4 by Methanogenic Microbes for Use in Valued-added Geologic Carbon Capture and Sequestration

We are currently looking for one (1) postdoctoral researcher to work on this project, in collaboration with Petronas Research Sdn. Bhd. (PRSB). It is a multi-disciplinary project, with researchers coming from several UTM faculties and CoE (Department of Biosciences and Department of Physics, Faculty of Science; School of Chemical Engineering and School of Mechanical Engineering, Faculty of Engineering; and Advanced Membrane Technology Research Centre) together with reservoir geology and geochemistry researchers at PRSB.

Project summary:

Carbon capture and storage (or sequestration) (CCS), is the process of capturing CO2 from large-scale emitters such as fossil fuel refineries, power plants and product manufacturing industries, and transporting it to a storage site. This prevents the CO2 re-entry into the atmosphere. There are several routes available for CCS, which can be divided into physicochemical, biological, and geological route. CO2 sequestration in deep subsurface formations, such as oil and gas reservoirs provides several advantages, such as enhanced oil recovery, and the capability to store up to two thirds of the CO2 in underground systems. The injected CO2 can also be transformed into CH4 by microbes for energy recovery as value-added options, in the presence of suitable electron donors, for example formate and H2.

This exploratory project will involve cultivation of methanogens under laboratory conditions and evaluation of the CO2 to CH4 conversion capacity. It will also involve lab scale reactor optimisations for the production of H2. Self-designed reservoir-mimic reactor will be used for larger scale methanogenesis reactions with CO2 and H2 as feedstocks. Depending on sample availability, microbial community analysis and methanogenesis characterisations will also be done on environmental samples.

Candidate requirements:

Open to both Malaysian and international candidates.

PhD (in biochemistry, biotechnology, chemical engineering, bioprocess engineering, or any related fields) from local or foreign universities.

Experience in any of these skills are an advantage: archaea handling, anaerobic reactor systems, reservoir biology, microbial ecology.

The position is on contract-basis (renewable up to 24 months), based on the candidate and project performance.

A monthly salary of MYR5,000 will be provided.

How to apply:

Kindly e-mail your CV and cover letter to the project leader, Dr. Mohd Firdaus Abdul Wahab at

Only selected candidates will be contacted for interview.

Position is open until filled.

Book Preface

“Proteins are the basic building blocks of life. They are defined as large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a variety of functions in the cell, including catalysing metabolic and biochemical reactions, assisting DNA replication, responding to external and internal stimuli, and transporting molecules from one location to another intra-cellularly or extra-cellularly. The study of proteins is important in the fields of biomedicine, environmental sciences, and for industrial applications. The understanding on how protein works at the molecular level assists in the development of new disease therapy, discovery and improvement of the activity of industrially- important enzymes, and discovery of beneficial secondary metabolites in medicinal plants, among many other interesting applications.

Investigation of proteins at the molecular level requires specialised instruments and precise techniques. Other than the commonly used sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and Western blotting (also known as protein immunoblotting), there are many other advanced techniques currently used which include surface plasmon resonance (SPR) spectroscopy, mass spectrometry (MS), X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, cryo-electron microscopy (cryo-EM), and circular dichroism (CD) spectroscopy. Computational methods are also indispensable in supporting wet lab experiments, and to provide precious information not currently observable with wet lab experiments.

This edited book is aimed at showcasing various research on proteins previously or currently being carried out at UTM and at affiliated laboratories. With the acquisition of increasingly sophisticated instruments, software, and the development of many new techniques, research on protein science is currently on the rise. This book demonstrates the research capability of our young and established researchers, and hopefully will serve as a networking guide for researchers interested in the field.”

Understanding the Microbiomes of Green Leafy Vegetables using Multi-omics Approaches

Food security is a very important issue nowadays. It is an already complex issue made worse by climate change, and the growing scarcity of arable land due to rapid urbanisation. The UN has reported that “815 million people are hungry today, and the additional 2 billion people expected to be undernourished by 2050”. Goal 2 (Zero Hunger) of the UN Sustainable Development Goals (SDG) calls for an increased investment in agricultural research to increase the agricultural productive capacity, particularly in developing countries.

Genetic engineering of food crops has the potential to provide the promising solutions, by providing the technology to develop higher yield, drought resistance, and nutritionally-enhanced food crops. However, the public perception of genetically-modified organisms (GMO) and transgenic plants has hampered the acceptance of many GM products.

Advancements in microbiology and microbial ecology has shed light on the importance of plant-associated microorganisms, particularly the community around the root region (rhizosphere). It is now known that there is a complex network of interactions between plants and their root microbes, increasing the plant nutrient uptake, and provide resistance to biotic and abiotic stresses. The rhizosphere is populated by a diverse range of microorganisms, and rhizobacteria are the bacteria colonizing this habitat with the ones that promote plant growth are called plant growth-promoting rhizobacteria (PGPR) (Beneduzi et al., 2012). These PGPR can be used to enhance agricultural productivity without using plant genetic modifications, or synthetic fertilisers. But understanding these PGPR and how they interact with their plant hosts requires the latest technologies in microbial ecology, molecular biology, plant sciences and chemical analysis.

I joined the Swarup Lab at the National University of Singapore (NUS) in January 2019, as part of my post-doctoral training, to learn more about these latest technologies. My work here involves the use of multi-omics analysis (metagenomics, metatranscriptomics and metabolomics) to study plant-microbial interactions, particularly how the PGPR at the root region affect the growth of green leafy vegetables. Multi-omics analysis uses information obtained from DNA, RNA and small chemical molecules (known as metabolites) found in the plant rhizosphere. I will also use advanced culturing tools to culture and characterise the complex bacterial communities in the rhizosphere. Bacteria found to have beneficial plant improvements traits can be applied to enhance the yield of agricultural products, in this case the leafy vegetables commonly used in urban farming. This microbial-assisted plant growth enhancement technology can lead to a more sustainable agriculture, lowering the use of chemical fertilisers, pesticides and herbicides.
