Ivanytsia; Odessa І.І. Mechnikov National Univ. – Odesa, 2015.https://dspace.onu.edu.ua/handle/123456789/11936Facultatively-anaerobic endosporeformers (FAE; in most from Bacillaceae, Paenibacillaceae and Planococcaceae families) are ubiquitous in nature and represented in all available biotopes (Mandic-Mulec I. et al., 2015). Their representation in sea has been only begun to be investigated. Black sea is interesting water area for such investigations because of the unique geological history and combination of physicochemical conditions. Prevalence of the FAE in different biotopes is a rarely investigated parameter, but interesting from ecological point of view.enBlack seaFacultatively-anaerobic endosporeformers FAEBacillaceae familiesPaenibacillaceae familiesPlanococcaceae familiesArticle
