Hard work pays off, as demonstrated by Relebohile Matobole (MSc student in IMBM) who walked off with a poster prize at the UWC Science faculty research open day held on Tuesday 28 October 2014. His work showed how microbes isolated from South African sea sponges could be induced to produce antimicrobial compounds under different growth conditions which would not be identified under normal screening conditions.

Congratulations Rele, you did us proud !

As luck would have it, Kulani Mhlongo (PhD student in IMBM) also won a hamper from Whitehead Scientific. Thank you to Whitehead and congratulations Kulani !

Victoria Ontong receives the prize from Merck representative Tamara Fedderke

Victoria Ontong won the prize for the best third year student at UWC Biotechnology. She won a cash prize and trophy presented by Merck representative, Tamara Fedderke. Congrats!

On the 12th of June 2014 the Soccer World Cup kicked off and IMBM was in a celebratory mood ! We took the opportunity to get all the lab members together for a kick-off party on the 13th with Nacho’s, Pão de queijo’s, Caipirinha’s and a few Corona’s (Mexico vs Cameroon in Brazil :)) before watching the first few games together. What a team !!

IMBM is now the proud host of a Q-Pix 2 colony picking robot, named Pixie. A conversation between Assoc. Prof. Marla Tuffin and Prof Esta van Heerden at UFS (Grant holder for the Q-Pix 2), asking if IMBM could use their robot for library screening, ended with an agreement to ship the underused robot to IMBM where it could be put to work immediately on a variety of metagenomic based projects and in the process establishing a new collaboration between the two labs. IMBM has in the past made use of the same class of robot hosted by CSIR in Pretoria for screening of large metagenomic libraries.

This together with a newly purchased MicroFill Microplate Dispenser enhances the Institutes ability to screen metagenomic libraries in a high throughput manner and complements the programs which are underway to develop in vitro screening platforms.

Professor Marcel Jaspars and Dr. Rainer Ebel from the Marine Biodiscovery Centre, University of Aberdeen presented their work in discovery of secondary metabolites from marine and extremophilic sources. The natural chemical diversity from unexplored environments is being used to combat infectious diseases that are increasingly resistant to the current generation of antibiotics.

“Antibiotic abyss: The extreme quest for new medicines”

This is the title of the recently (27 Jan 2014) published New Scientist article showcasing the PharmaSea project which aims to explore extreme marine habitats to discover novel antibiotics. IMBM is a proud partner of the program launched in October 2012 (see IMBM involved in €9m EU-project below). Follow the link below to read the full article.

The South African Society for Microbiologist (SASM) held their biannual conference this year in Bela Bela, Limpopo, hosted by the University of Witwatersrand. IMBM joined the rest of the South African microbiology community for three days of presentations and posters on the latest developments in South African microbiology.

Representing IMBM were Lonnie van Zyl, Tanya Nyman, Lucas Black and Brent Fortune who presented talks. William Mavengere, Reyghana Hoosen, Walter Novendo, Wesley Williams and Zimasa Sithole were also in attendance presenting posters.

The plenary presentations provided interesting insights into current cutting edge research. Peter Lipke from Brooklyn College, New York, USA described the role of amyloids at the surface of yeast in adhesion and flocculation. Using Atomic Force Microscopy (AFM) they directly observed the interaction of amyloids with a cell surface. By describing how amyloids on the cell surface activates adhesion, the mechanism of the pathogen interacting with the host and biofilm formation becomes clearer. Micheal Goodin from the University of Kentucky observed directly how viruses interact with a plant host, and infect other plant cells despite the plants thick cell walls. A virus is able to use the microtubule network of a cell as a highway of infection to transport themselves to the plasmodesmata situated at the cell walls which are connected to the adjacent cells. Doug Rawlings from Stellenbosch University discussed the South African technology that has been exported to the world for the extraction of minerals using bacteria. And finally the diversity and applications of magnetotactic bacteria was discussed by Nicolas Ginet and Christopher Lefevre from the French National Centre for Scientific Research.

Nicolas and Christopher followed their presentations with an excellent workshop on the sampling and identification of magnetotactic bacteria, followed by a sampling expedition to the water bodies surrounding Bela Bela. Pictures and a description of the workshop can be found here.

The conference was not all about work, with IMBM taking some time to enjoy the hot-springs and a beer or two. Pictures of the conference can be found here.

Deep in the cold waters of the world’s oceans lurk marine organisms which could hold the key to one of the biggest challenges of modern medicine – resistance to antibiotics. The widespread use and misuse of antibiotics is leading to the development of strains of bacteria that are not susceptible to standard drug treatments. The World Health Organisation has warned that rising resistance to antibiotics could mean the “end of modern medicine as we know it”.

The PharmaSea project is part of a worldwide mission traveling to remote locations in China, New Zealand, Chile, Antarctica, the Arctic and the South African coastline. Scientists collaborating on the PharmaSea project, including a group of IMBM researchers from the University of the Western Cape, are hoping that organisms found, such as deep-sea sponges and bacteria, could help create vital new antibiotics. Samples collected by the collaborators in the PharmaSea project will be analyzed at the state of the art labs at the University of Tromso.

Dr Joff Lacey joins a team of scientists in Norway hoping to discover the next antibiotic in the fjords of Norway. Species and organisms that are collected on each expedition are meticulously sorted and then tested for their ability to kill bacteria.
