Abstract

Identification of the genus Cercospora is still complicated due to the host preferences often being used as the main criteria to propose a new name. We determined the relationship between host plants and multilocus sequence variations (ITS rDNA including 5.8S rDNA, elongation factor 1-α, and calmodulin) in Cercospora spp. to investigate the host specificity. We used 53 strains of Cercospora spp. infecting 12 plant families for phylogenetic analysis. The sequences of 23 strains of Cercospora spp. infecting the plant families of Asteraceae, Cucurbitaceae, and Solanaceae were determined in this study. The sequences of 30 strains of Cercospora spp. infecting the plant families of Fabaceae, Amaranthaceae, Apiaceae, Plumbaginaceae, Malvaceae, Cistaceae, Plantaginaceae, Lamiaceae, and Poaceae were obtained from GenBank. The molecular phylogenetic analysis revealed that the majority of Cercospora species lack host specificity, and only C. zinniicola, C. zeina, C. zeae-maydis, C. cocciniae, and C. mikaniicola were found to be host-specific. Closely related species of Cercospora could not be distinguished using molecular analyses of ITS, EF, and CAL gene regions. The topology of the phylogenetic tree based on the CAL gene showed a better topology and Cercospora species separation than the trees developed based on the ITS rDNA region or the EF gene.

Abstract

Development of Database for Indigenous Indonesian Microorganisms. The objective of the research is to create and develop a database of indigenous Indonesian microorganisms based at the University of Indonesia. Development of the database of indigenous Indonesian microorganisms was carried out in several stages, i.e. data identification, database design, programming, data entry, testing and debugging, and repairing and maintenance. Development of the database utilized the licensed software of General Public License (GPL), which include Linux RedHat 9.0 (operating system), Apache ver. 2.20 (web server), MySQL ver. 4.2 (database server), and PHP ver. 4.3 (web interface programming language). The result of this research is a database named UI Bioinfo which has the following facilities: online catalog search for UICC (University of Indonesia Culture Collection) strains collection and sequence homology search utility through BLAST (Basic Local Alignment Search Tool). Integrated information on strains collection was first carried out on the yeast collection. At present, UI Bioinfo contains information for 297 strains that includes isolation data, morphological descriptions, physiology-biochemical characteristics, and images. Moreover it also contains sequence data from the large subunit (LSU) ribosomal RNA gene and the internal transcribed spacer (ITS) regions. UI Bioinfo can be accessed from the following site: http://152.118.162.250/bio/. Future development will be addition of data from the other collections in UICC

Abstract

Antifungal Activity of Cumin Oil Against Candida parapsilosis SS25, C. orthopsilosis NN14, C. metapsilosis MP27, and C. etchellsii MP18. Many kinds of spices are used in Indonesia, one of them is white cumin seed. This spice is used not only for cooking, but also for traditional medicine. This study reported of antifungal activity from white cumin’s essential oil. Extraction and identification of Cumin oil were carried out. We obtained 2.5-3.0% of white essential oil which was colorless or light yellow color. GCMS analysis revealed that there were 12 peaks. Based on peak’s intensity the oil were dominated by 4 compound i.e. cuminaldehide (35.44%), ρ-cymene (34.77%), β-pynene (15.08 %) and γ-terpinene (8.15%). Growth inhibition zone determination has been carried out by diffusion disc and direct method against yeast i.e. C. parapsilosis SS25, C. orthopsilosis NN14, C. metapsilosis MP27, and C. etchellsii MP18. The results showed that all of the yeasts were sensitive to cumin oil. The inhibition zone radius were 13.4-16.5 mm. The cumin oil showed the inhibition of yeast growth with MIC values of 0.028%-0.042% and MFC values 0.09%- 0.14%, while nystatin had MIC values 0.40%-0.50% and MFC values 3.0%-4.0%. The activity of cumin oil was very strong as antifungal.
