Developing of large-scale lignite excavation can often generate socio-environmental conflicts between mining-energy companies and various stakeholders, such as local communities or ecological organizations. In this context indication of potential channels of communication with local communities’ is needed to increase the level of their satisfaction with own knowledge and to optimize the social dialogue. The paper presents the results of a questionnaire survey conducted in selected communities of the Łódź voivodeship where surface mining exists at present (Kleszczów) or will be developed soon (Złoczew). They were realized with the Computer Assisted Telephone Interviewing on the representative groups of adults. The paper contains analysis of two selected closed-type questions: the first one concerned self-assessment of knowledge level of lignite mining, the second one - sources of information on mining activity. Previous media reports on mining activity in the examined areas were analysed, too. As it seems, various means of social communication should be used: television and radio are the major source of information for local communities, printing press and the Internet are important as well. A detailed set of communication channels and the content of individual messages should be carefully selected for specific target groups (depending on gender, age and education). It should be emphasized that a properly conducted public debate may prove to be one of the factors determining the success of mining-energy investments and sustainable development of some regions.

Ecology of facultative anaerobic, mesophilic, spore-forming and cellulolytic bacteria (FAMSCB) is poorly understood. In the literature, there are only scant information about the impact of fertilization and type of the crop on the occurrence of FAMSCB. The aim of our study was to demonstrate the effect of the addition of various brown coal fine-based composts on a chemical properties and the occurrence of in the bulk and rhizosphere soil from selected plants. Soil under the experimental plants was slightly acidic, and did not differ in macronutrient content. The number of investigated groups of microorganisms depended on the type of compost and ranged from 9.99 to 3186.9 cfu (colony forming units) per gram of dry soil. All composts stimulated the number of cellulolytic bacteria in a bulk soil. In the case of rhizosphere soil, compost containing effective microorganisms (EM) reduced the number of FAMSCB. The largest number of investigated rizosphere microorganisms were found in the cultivation of cherries, fertilized with compost prepared from brown fine with waste from the production of fruiting bodies of Pleuretus ostreatus (3186.9 cfu per gram of dry soil).

Ekologia względnie beztlenowych, mezofilnych, przetrwalnikujących bakterii celulolitycznych (WBMPBC) jest mało poznana. W literaturze przedmiotu znajdują się tylko nieliczne informacje dotyczące wpływu nawożenia oraz rodzaju uprawianej rośliny na występowanie w glebie WBMPBC. Dlatego celem naszych badań było wykazanie wpływu dodatku do gleby kompostów na bazie miału węgla brunatnego na właściwości chemiczne i liczebność względnie beztlenowych, mezofilnych, przetrwalnikujących bakterii celulolitycznych (WBMPBC) w glebie ryzosferowej i pozaryzosferowej wybranych roślin. Gleba pobrana z obiektów doświadczalnych była słabo kwaśna (pH – 6,2-6,4) i nieznacznie się różniła się zawartością makroelementów. Liczebność badanej grupy drobnoustrojów w glebie zależała od rodzaju kompostu i wynosiła od 9,42 do 3186,9 jtk (jednostki tworzące kolonie) w gramie suchej masy gleby (s. m. gleby). Wszystkie komposty stymulowały liczebność bakterii celulolitycznych w glebie pozarysoferowej. W przypadku ryzosfery kompost zawierający efektywne mikroorganizmy (EM) redukował liczebność WBMPBC. Największą liczebność badanej grupy drobnoustrojów stwierdzono w ryzosferze spod uprawy wiśni, nawożonej kompostem przygotowanym z węgla brunatnego z odpadem po produkcji owocników Pleuretus ostreatus (3186,9 jtk w g. s. m. gleby).
