Science Its a girl thing
Innocensia Mangoato’s research on using cannabis to reverse anticancer drug resistance has been awarded in the prestigious Women in Science Awards.

“There’s this misconception among young people that science is difficult and that it’s somehow a man’s domain,” says Innocensia Mangoato, Masters student in Pharmacology, who has just been awarded in the prestigious Women in Science Awards by the Department of Science and Technology.

Cannabis research

Innocensia won in the Master’s Degree category for her research on the use of cannabis in reversing anticancer drug resistance. Her department had to apply for a special permit to grow cannabis for research and medicinal purposes.

“Her findings have already indicated a promising reversal of resistance to drugs in a variety of cancers. We plan to explore these results further in a possible PhD,” says her study leader, Prof Motlalepula Matsabisa.

Innocensia says she’s always had an interest in science, and initially wanted to study medicine. She ended up doing a BSc in Physiology and Genetics.

She hopes that her research will help government to develop a policy around the use of cannabis for medicinal purposes which could ultimately lead to developing cancer treatment with fewer side-effects.

Female mentors

“My mentor during my Honours studies was Dr Makhotso Lekhoa. Her passion for her field and her patience in conveying it to others really inspired me. We have some very powerful women in our Pharmacology Department,” says Innocensia.

Passion for science 

“You know you’re passionate about your work when you find yourself going to the lab on Sunday afternoons!” she says. “I’m happy that I can be contributing to the knowledge production on this campus. And maybe one day I can be a mentor to other girls with that same passion for science.”

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
