“…They are also detected in air samples and are common environmental pollutants in production and housing spaces. Occurrence of them indoors is associated with increased humidity (Frączek and Kozdrój, 2013). The highest concentration of those airborne microorganisms was recorded in the station to operate machines (7.3 3 10 1 CFU/m 3 ).…”

“…According to the recommendations of the PN-89 Z-04111/ 02 and presented in it, the scale of actinobacterial air pollution at this location was moderate (Górny 2010). Frączek and Kozdrój (2013) conduced similar experiments in a subterranean spa located in the former salt-mine of Bochnia. They report the average concentrations of actinobacteria underground ranged from 0 to almost 4 3 10 1 CFU/m 3 throughout the year.…”

We determined the species composition and the concentration of colony forming units of airborne bacteria and fungi in a coal mine in Poland. We sampled at six locations in a working shaft at about 500-600 m below ground level. Air samples were collected between 6 and 9 a.m. using the impact method onto Potato Dextrose Agar and TSA. The volume of air filtered for each coalmine sample was 50 L. We found 11 fungal species, with Penicillium meleagrinum and P. notatum as the most common. Six bacterial genera were identified, with Micrococcus spp. as the most common. There were no pathogenic fungi or bacteria identified. The concentration of fungal spores and bacteria in the coal mine air is not a direct hazard to mine workers.

“…In soil, herbicides undergo biodegradation, a complex process which involves microorganisms able to degrade chemical compounds [1,2]. Actinomycetes belong to a group of microorganisms which play an important role in decomposition of various chemical substances and participate in carbon cycling and formation of humic compounds in soil [3,4].…”

A laboratory experiment was completed to determine the effect of the herbicides Alister Grande 190 OD, Fuego 500 SC and Lumax 537.5 SE on counts of actinomycetes as well as the activity of enzymes and their resistance to herbicides. Sandy loam was mixed with appropriate doses of the herbicides, such as: 0 - the control, 1 - technological dose and doses 20-, 40-, 80- and 160-fold higher than recommended. On day 20, 40, 80 and 160, counts of actinomycetes and activity of urease, acid phosphatase and alkaline phosphatase were determined. For 160 days, soil was incubated at 25°C and its moisture content was maintained on a constant level equal 50% of water capillary capacity. On days 20 and 80 of the experiment, the ecophysiological (EP) and colony development (CD) indices were computed. Additionally, the resistance (RS) of enzymes to the herbicides was assessed on day 20 and their resilience index (RL) was determined on day 160. It has been found out that soil contamination with herbicides contributed to elevated counts of actinomycetes. The highest number of these microorganisms was observed in soil with Lumax 537.5 SE, and the lowest one appeared in soil with Alister Grande 190 OD. The CD for actinomycetes was the highest in treatments with Fuego 500 SC and the highest EP was determined in soil with Alister Grande 190 OD. Application of the herbicides in doses from 20- to 160-fold higher than recommended by the manufacturer significantly increased the activity of acid and alkaline phosphatases. With respect to the activity of urease, the herbicides produced variable effects. The strongest inhibitory effect on the activity of urease was produced by Fuego 500 SC, which reduced the activity of this enzyme by 13.39% when added to soil in a dose exceeding by 160-fold the recommended rate. The RS of the enzymes to the herbicides ranged from 0.461 to 0.955. Urease was the most tolerant to soil contamination with the herbicides.

Comparative analysis of airborne bacteria and fungi in two salt mines in Poland

The aim of this work was to determine the genera or species composition and the number of colony forming units of airborne bacteria and fungi, respectively, in two salt mines in Poland “Wieliczka” (Lesser Poland) and “Polkowice–Sieroszowice” (Lower Silesia). Both of them are working environments characterized by extreme conditions, and additionally “Wieliczka,” officially placed on the UNESCO World Heritage Sites’ list, plays a role of tourist attraction. There are also some curative chambers located in this mine. Air samples were taken once in December 2015, between 6:00 a.m. and 9:00 a.m. There were nine measurement points located about 200 m underground in “Wieliczka” and six measurement points located in the working shafts about 400 m underground in “Polkowice–Sieroszowice.” The total volume of each air sample was 150 L. Air samples, collected in individual measurement points of both salt mines, were inoculated on two microbiological media: potato dextrose agar and tryptic soy agar using the impact method. We identified 10 and 3 fungal genera in the “Wieliczka” Salt Mine and in “Polkowice–Sieroszowice,” respectively. The most common were fungi of the Penicillium genus. In both mines, the Gram-positive bacteria of genus Micrococcus were detected most frequently. Among identified microorganisms, there were neither pathogenic fungi nor bacteria. The most prevalent microorganisms detected in indoor air were Gram-positive cocci, which constituted up to 80% of airborne microflora. Our results showed that microorganisms recorded in the air samples are not a threat to workers, tourists or patients. Neither pathogens nor potentially pathogenic microorganisms, listed as BSL-2, BSL-3 or BSL-4, were detected. The microbes identified during our analysis commonly occur in such environments as the soil, water and air. Some of the detected bacteria are component of natural microflora of human skin and mucous membranes, and they can cause only opportunistic infections in individuals depending on their health condition.
