Metadata record for data from ASAC Project 2597. See the link below for public details on this project. The project aims to study the diversity of Antarctic fungi and protists. Comparison with tropical species will be made based on their morphological, physiological, biochemical and molecular characteristics. Exploration of these ecologically extreme habitats, hopefully will lead to the discovery of a considerable number of novel and more diverse microbial species compounds. Effect of media, sea water, temperature and pH on the growth of selected Antarctic fungi. The data provided are the diameters of fungal colonies (in millimetres) grown on different types of media - potato dextrose agar (PDA) (Difco brand) and corn meal agar (CMA) (OXOID brand), with and without sea water at 4 degrees C and 25 degrees C; and also fungal colonies grown on different media pH: pH 5, 5.6, 6, 7, 8 and 9. The fungi used in this study were isolated from various areas in the Windmill Islands, Antarctica. The fungi tested were Phoma sp., Antarctomyces sp., Mucor sp., Aureobasidium sp. and Thelebolus sp. The objectives of this study were to find suitable conditions under which the tested fungi can grow well and also to differentiate between psychrophilic, psychrotrophic and mesophilic fungus among the isolated fungi. The measurements were done using normal iron ruler. The media with sea water were created by adding 7.18g of artificial marine salt in 400 ml of distilled water in which were added PDA powder before autoclaving. The media with different pH were created by adjusting the pH with sodium hydroxide (NaOH) and hydrochloric acid (HCl). The data for the effects of different media types were taken from 10 October 2004 until 19 October 2004 while the others were taken from 15 December 2004 until 24 December 2004. The fields in this dataset are: Media pH Date Temperature (Celsius) Time (hours) Growth rates (mm)
