It has been a very busy start to the year for the staff managing the CMW Fungal Culture Collection at FABI. The FABI collection is one of the largest private collections of fungal cultures in the world and was established in the 1980's by FABI Director, Prof. The collection is especially known for accommodating focus groups of fungal agents of tree disease in commercial forestry, and includes some of the most comprehensive collections in existence of the ophiostomatoid fungi (Ophiostoma, Sporothrix, Ceratocystis etc. The preparation, storage, maintenance and cataloguing of this collection is of vital importance and this is done by a group of six staff and postgraduate students. The fungal cultures are preserved in four different media: sterile water, agar slants, mineral oil and freeze dried with a skim milk formula. Dr Marincowitz runs a tight ship with every culture sample coming in being logged and recorded both electronically and manually on data cards. The CMW collection forms the foundation of much of the research in FABI.
The TPCP-CTHB groups in FABI have a tradition of officially celebrating the first publication of a paper in an ISI-rated scientific journal by a postgraduate student from the work of either their PhD or MSc.

FABI hosted two groups of High School students over the past two weeks. The visit by students from St Mary’s is now an annual occasion where the girls are also addressed by female academics. The girls were then given the opportunity to do gel electrophoresis preparation to tie in with the biotechnology module currently being covered in their school syllabus. Affies is located close to the University and this is the second year the school has sent its students to visit the Institute to get an insight into the work being done at the University and gain a practical insight into research being conducted. The students are currently studying bacteria and viruses and were hosted by Prof. Students were briefed on biological Nitrogen fixation in plants, given a chance to inoculate and plate bacterial cultures before being told about fungal and bacterial symbioses in indigenous Protea species. Visits by scholars forms an important part of FABI’s mandate to educate the youth and instill an interest in Science by exposing them to high level research being conducted at the Institute.
In a joint effort, staff and students again showed that many hands make light work at the year’s first TPCP-CTHB Tree Planting Day. Everyone swapped their labcoats for shovels, secateurs, wheelbarrows, trolleys and brooms to ensure the tasks were finished by lunchtime. The Tree Planting Day is a team building exercise as much as a time saving effort by the FABI staff under the watchful eye of Dr Wilhelm de Beer. More photos here.
