SCELSE Virtual Tour

Get a glimpse of the SCELSE experience with this virtual tour! Zip around this NTU-based, three-storey lab by clicking on the arrows/circles. The tour starts on level 1 and leads you to the B1 offices, and labs on B2 and B3. Downloading of the visuals may take a while, do be patient and enjoy this tour. 

Utilising State-Of-The-Art Technology

Our understanding of biofilms is rapidly unfolding with the advent of sophisticated technologies. SCELSE’s state-of-the-art facilities feature:

High Throughput Sequencing Unit using the two sequencing platforms illumina HiSeq and MiSeq. This is supported by a computer cluster with 2,720 core processors and liquid handling robotics.

The SCELSE Advanced Biofilm Imaging Facility providing instrumentation tailored to meet the highly specialised and continually evolving needs of biofilm ELSE research.

SCELSE has an an extensive range of bioreactors – from laboratory to full scale – to investigate how microbial community structure and function evolve under controlled conditions.

SCELSE has a strong in vivo experimentation platform to assess biofilm-based chronic infections and develop approaches for understanding and controlling such infections.

Shared Technology

Metabolomics, Experimental and Analytical Facilities
SCELSE collaborates with the NUS Environmental Research Institute (NERI), establishing a high-throughput metabolomics capabilities to detect, analyse and identify thousands of small molecules and ascribe them to chemical classes and families.

Highly complex chemical and metabolite mixtures in liquid or vapour phase can be deconvoluted and resolved to 10s of 1000s of individual chemical moieties. The analytical facilities are further supported by our data handling platforms utilising

  • Automated workflows,
  • Proprietary and in-house pipelines and
  • Metabolite repositories/database.

Integrated workflows have been developed to detect volatiles and other relevant chemical classes from plant and environmental samples. A database with information on more than 30,000 compounds has been created, categorised into several chemical classes of biological relevance. A targeted metabolite panel for investigating plant-microbiome associations has been developed, along with a number of methods to analyse metabolites directly from samples.

Plant microbiome capabilities
A framework for rapid microbial products has been development from microbes in diverse urbanised or natural terrestrial habitats. The framework includes various computational pipelines such as genomes from metagenomes assembly, hybrid genome assembly and, microbial interaction prediction by genome scale metabolic modelling.

Field-based capabilities – waterways
A wide array of field-based capabilities has been built, ranging from park soil, waterway sediments, greenhouse gas emissions, water and rhizosphere under the study of Plant-Air-Water-Soil-Sediment (PAWS2) axis of urban waterways ecosystems.

Plant-biofilm relationships
A novel modular airflow system was developed to study volatile-mediated interactions between biological systems, for example, the effect of plant root volatiles (rVOCs) on soil microbial community. In this system, sterile air is forced through the root-soil system using a aerator and withdrawn into another chamber using vacuum. A variety of plant species can be tested in the source chamber that can scaled for plant size. This setup also allows vapor absorbing cartridges to be attached, thus providing VOC mixtures to be analysed using mass spectrometry.

Plant-microbiome relationships
A custom-made mesocosm system, named Live-Exudation Assisted Phytobiome Cultromics System (LEAP-CS) is driven by ecological principles governing the interactions within the complex phytobiomes.

The system is designed to:
– Simulate native associations between the plant hosts and its associated microbiomes;
– Maximise metabolic exchange and chemical dialogue to enhance processes underlying plant-microbe interactions;
– Enable concurrent data collection of plant phenotypic/molecular traits, microbiome composition, and interacting metabolites.

It is a modular system that supports:
– Easy manipulation of the microbiome communities;
– Chemical complementation assays;
– Different biological and analytical platforms for phenotyping;
– Non-invasive in-situ growth-profiling.

Singapore Phenome Centre
The Singapore Phenome Centre (SPC) supports research in the clinical, biological and environmental sciences. It is a unit of the NTU Integrated Medical, Biological, and Environmental Life Sciences (NIMBELS) cluster and is co-funded by NTU Lee Kong Chian School of Medicine and the School of Biological Sciences (SBS), and SCELSE, in association with the National Phenome Centre at Imperial College London and Waters Corporation.

SPC’s research projects involve the study of phenotypes (the traits that are displayed) by profiling critical biomolecules such as metabolites and lipids. The tools available for such investigations include the state-of-the-art ultra-performance liquid chromatography mass spectrometry (UPLC-MS) and nuclear magnetic resonance (NMR) spectroscopy technologies.

SPC is an interdisciplinary research platform, focusing on the areas of microbiome health, nutritional metabolism and health, and aiming to enhance analytical capabilities to support research efforts and to deliver world-class metabolic phenotyping services to the NTU’s scientific community, Singapore’s researchers, and industries in Singapore and beyond.

SPC houses a suite of instrumentation to meet the varied needs of its interdisciplinary researchers, including:

Liquid chromatography-mass spectrometry (LC-MS)
The LC-MS facilities at SPC include four high-resolution quadrupole/time-of-flight (QToF) mass spectrometers for untargeted profiling and biomarker discovery and two tandem quadrupoles (TQ) for quantitative targeted analysis of metabolites.

SPC also has two SYNAPT high-definition mass spectrometry instruments with desorption electrospray ioniation (DESI) and matrix-assisted laser desorption ionisation (MALDI) mass spectrometry imagining capability.

Nuclear magnetic resonance (NMR) facility in SPC
SPC is the first centre in Singapore and Southeast Asia to be equipped with the In Vitro Diagnostics Research (IVDr) system. This 600 MHz NMR IVDr system can screen complex mixtures by 1H NMR for rapid identification and quantification of metabolites. The system also quantifies 112 lipoproteins, including major components of triglycerides, cholesterol, HDL-cholesterols, LDL-cholesterol, Apo-A1, Apo-A2 and Apo-B100.

Chemical Biology

The Chemical Biology programme at SCELSE focuses on identifying small molecules as modulators and probes to control and study bacterial biofilms. By screening synthetic chemical and natural product libraries against cell-based assays, we aim to discover novel small molecules that possess the ability to control bacterial signalling systems, namely quorum sensing networks and cyclic di-GMP signalling pathways, in bacteria.

We also aim to identify compounds that allow us to differentiate the biofilm mode of growth from the planktonic mode of growth. A structurally diverse, fluorescent chemical library is screened to pick out structures that interact with biofilm-specific surface proteins and macromolecules, including amyloids. These projects identify small molecular structures that can serve as leads for the development of anti-microbial probes and drugs.

St John's Island National Marine Laboratory
To support strategic marine science research in Singapore, the National Research Foundation (NRF) had established the St John’s Island National Marine Laboratory (SJINML) as a National Research Infrastructure (NRI) to support multidisciplinary & multi-institutional marine science research.

Pertinent to SCELSE’s research, the marine station at SJINML includes a climate-controlled aquaria biosafety-level-2 facilities to support upcoming disease-and-pathogen-focused research and a 10m seawater current flume to aid studies in marine hydrodynamics. The station is also equipped with aquaria with fibreglass tanks and labs that enable researchers to conduct analytical chemistry, biomolecular work or take high-resolution bio-imagery.
