R. FORAR. LAIDIa, A. ABDERRAHMANEb, A. A. HOCINE NORYAc. a Department of Natural Sciences, Ecole Normale Superieure, Vieux-Kouba, Algiers – Algeria b,c Institute of Genetic Engineering and Biotechnology, Baghdad - Iraq. a email: [email protected] Abstract A total of 35 actinomycetes strains were isolated from and around Baghdad, Iraq, at a depth of 5-10 m, by serial dilution agar plating method. Nineteen out of them showed noticeable antimicrobial activities against at least, to one of the target pathogens. Five among the nineteen were active against both Gram positive and Gram negative bacteria, yeasts and moulds. The most active isolate, strain RAF-11, based on its largest zone of inhibition and strong antifungal activity, especially against Candida albicans and Aspergillus niger, the causative of candidiasis and aspergillosis respectively, was selected for identification. Morphological and chemical studies indicated that this isolate belongs to the genus Streptomyces. Analysis of the 16S rDNA sequence showed a high similarity, 98 %, with the most closely related species, Streptomyces labedae NBRC 15864T/AB184704, S. erythrogriseus LMG 19406T/AJ781328, S. griseoincarnatus LMG 19316T/AJ781321 and S. variabilis NBRC 12825T/AB184884, having the closest match. From the taxonomic features, strain RAF-11 matched with S. labedae, in the morphological, physiological and biochemical characters, however it showed significant differences in morphological characteristics with this nearest species, S. -

INVESTIGATING THE ACTINOMYCETE DIVERSITY INSIDE THE HINDGUT OF AN INDIGENOUS TERMITE, Microhodotermes viator by Jeffrey Rohland Thesis presented for the degree of Doctor of Philosophy in the Department of Molecular and Cell Biology, Faculty of Science, University of Cape Town, South Africa. April 2010 ACKNOWLEDGEMENTS Firstly and most importantly, I would like to thank my supervisor, Dr Paul Meyers. I have been in his lab since my Honours year, and he has always been a constant source of guidance, help and encouragement during all my years at UCT. His serious discussion of project related matters and also his lighter side and sense of humour have made the work that I have done a growing and learning experience, but also one that has been really enjoyable. I look up to him as a role model and mentor and acknowledge his contribution to making me the best possible researcher that I can be. Thank-you to all the members of Lab 202, past and present (especially to Gareth Everest – who was with me from the start), for all their help and advice and for making the lab a home away from home and generally a great place to work. I would also like to thank Di James and Bruna Galvão for all their help with the vast quantities of sequencing done during this project, and Dr Bronwyn Kirby for her help with the statistical analyses. Also, I must acknowledge Miranda Waldron and Mohammed Jaffer of the Electron Microsope Unit at the University of Cape Town for their help with scanning electron microscopy and transmission electron microscopy related matters, respectively. -

Keywords: antibiotics; genome mining; Herpetosiphon; myxobacteria; predation Abstract Bacteria, which prey on other microorganisms, are commonly found in the environment. While some of these organisms act as soli- tary hunters, others band together in large consortia before they attack their prey. Anecdotal reports suggest that bacteria practicing such a wolfpack strategy utilize antibiotics as predatory weapons. Consistent with this hypothesis, genome sequencing revealed that these micropredators possess impressive capacities for natural product biosynthesis. Here, we will present the results from recent chemical investigations of this bacterial group, compare the biosynthetic potential with that of non-predatory bacteria and discuss the link between predation and secondary metabolism. Introduction Microorganisms are major contributors to primary biomass pro- latter and their early occurrence in the history of life, likely duction and nutrient cycling in nature. -
Phylogenetic Analysis of Streptomyces Sp. H2AK Isolated from Soil in Kuşadası

H2AK isolated from soil in Kuşadası Demet Tatar1+* and Aysel Veyisoğlu2 1Department of Medical Services and Techniques, Osmancık Ömer Derindere Vocational School, Hitit University, Çorum, Turkey 2Department of Medical Services and Techniques, Vocational School of Health Services, Sinop University, Sinop, Turkey *Corresponding author: [email protected] +Speaker: [email protected] Presentation/Paper Type: Oral / Full Paper Abstract – Streptomyces is a genus of Gram-positive bacteria that has a filamentous form similar to fungi. Streptomyces produces bioactive secondary metabolites, such as antifungals, antivirals, antitumorals and various antibiotics. The aim of this study is to carry out phylogenetic analysis of Streptomyces sp. H2AK isolated from soil sample taken from the Kuşadası located near Aydın province. Streptomyces sp. H2AK, was picked after 14 days of incubation at 28˚C on Humic acid-vitamin agar containing Cycloheximide (50 µg/ml) ve Nalidixic acid (10 μg/ml). Genomic DNA isolation was performed according to DNA isolation method [1]. The 16S rRNA gene was amplified by PCR using universal primers 27f and 1525r. Phylogenetic analyses were performed by using three different algorithms with MEGA 7 software. H2AK showed the highest 16S rRNA gene sequence similarity with Streptomyces marokkonensis Ap1T (98.90 %). When the polyphasic taxonomic analyses were completed, Streptomyces sp. H2AK isolate may be introduced into the literature as a new species of the genus Streptomyces.
