Summary: | The paper presents the results of studies of epilithic phototrophic microorganisms colonization on CaCO3-containing samples (cubes of a chalk) in the nutrient medium with different concentrations of cupreous and plumbic salts. The fluorescens pulse amplitude modulation as well as the amperometric technique were used to control the action of Cu2+ and Pb2+ on the photosynthetic activity of enrichment cultures isolated from limestone of the Archangelskoe estate-museum historical buildings (XVIII—XIX c.). Исследовали эффект солей меди и свинца на степень обрастания образцов мела альго-бактериальными сообществами, выделенными с поверхности известняка памятников архитектуры государственного музея-усадьбы “Архангельское”, и физиологическое состояние накопительных культур микроводорослей. С этой целью определяли фотосинтетическую активность микроводорослей методами амперометрического определения выделения кислорода и импульсной амплитудной модуляции замедленной люминесценции хлорофилла. |
