Abstract
Microbial-based biostimulants that increase plant performance and ensure sustainable restoration of degraded soils are of great importance. The aim of the present study was to evaluate the growth promotion ability of indigenous Trichoderma ghanense, T. tomentosum and their complex on early rye seedlings in sustained grassland and arable soil. The impact of soil chemical properties on the ability of selected Trichoderma strains and their complex to promote plant growth was determined by the evaluation of the rye (Secale cereale L.) early seedling growth—measuring the length of shoots and roots as well as their dry weight. Trichoderma species were tested for their ability to produce extracellular degradative enzymes on solid media. Furthermore, the soil properties and CM-cellulase activity of soil were estimated. The indigenous Trichoderma strains possess the capacity to produce enzymes such as peroxidase, laccase, tyrosinase, and endoglucanase. The results indicated a significant (p < 0.05) increase in plant growth and the improvement of some soil chemical properties (total N, mobile humic and fulvic acids, exchangeable K2O, soil CM-cellulase activity) in inoculated soils when compared to the control. The growth of the roots of rye seedlings in sustained grassland was enhanced when T. tomentosum was applied (p = 0.005). There was an increase in total weight and shoot weight of rye seedlings when T. ghanense was used in the arable soil (p = 0.014 and p = 0.024). The expected beneficial effect of Trichoderma spp. complex on rye growth promotion was not observed in any tested soil. The results could find application in the development of new and efficient biostimulants, since not only do physiological characteristics of fungi play an important role but also the quality of the soil has an impact.

Abstract
The aim of this study was to evaluate occurrence of T. pulegioides α-terpinyl acetate chemotype, as source of natural origin α-terpinyl acetate, to determine its phytotoxic and antimicrobial features. Were investigated 131 T. pulegioides habitats. Essential oils were isolated by hydrodistillation and analyzed by GC-FID and GC-MS. Phytotoxic effect of essential oil of this chemotype on monocotyledons and dicotyledons through water and air was carried out in laboratory conditions; the broth microdilution method was used to screen essential oil effect against human pathogenic microorganisms. Results showed that α-terpinyl acetate was very rare compound in essential oil of T. pulegioides: it was found only in 35% of investigated T. pulegioides habitats. α-Terpinyl acetate (in essential oil and pure) demonstrated different behavior on investigated plants. Phytotoxic effect of α-terpinyl acetate was stronger on investigated monocotyledons than on dicotyledons. α-Terpinyl acetate essential oil inhibited seeds germination and radicles growth for high economic productivity forage grass monocotyledon Poa pratensis, but stimulated seed germination for high economic productive forage legume dicotyledon Trifolium pretense. α-Terpinyl acetate essential oil showed high antimicrobial effect against fungi and dermatophytes but lower effect against bacteria and Candida yeasts. Therefore, T. pulegioides α-terpinyl acetate chemotype could be a potential compound for developing preventive measures or/and drugs for mycosis.

Abstract
The aim of this study was to determine distribution of the Candida (C.) species in onychomycosis and analyses in vitro susceptibility to fluconazole and itraconazole. In recent years, cases of onychomycosis in Lithuania caused by Candida have increased significantly. In the period between 2009 and 2016, a total of 8149 clinical cases (outpatients and inpatients) were investigated at the Vilnius University Hospital Santaros Clinics (VUH SC). Candida yeasts were identified using VITEK 2 (BioMerieux, France) and IVD Maldi biotyper 2.3 (Bruker Daltonik GmbH, Germany), automated systems for identification of yeasts. The antifungal susceptibility to the Candida species were determined by disc diffusion. Candida spp. were the most frequently isolated pathogens in onychomycosis during the investigation period. The main species in onychomycosis were C. albicans (38.6%), followed by C. krusei (33.7%), C. tropicalis (11.1%), C. parapsilosis (7.9%), and other Candida (8.7%). The different antifungal susceptibility patterns among Candida species confirm the need to perform antifungal susceptibility in vitro testing of yeasts from patients with onychomycosis.

Abstract
Knowledge of the background activity concentrations of anthropogenic radionuclides before the start of operation of the new nuclear power plant in Belarus, BelNPP, is an issue of great importance for neighbouring countries. In this study, we provide the pilot characterisation of the Lithuanian part of the 30-km zone of the BelNPP, emphasising the forest plants, terrestrial mosses, forest organic and mineral topsoil to describe the preoperational radioecological state of the pine forest ecosystem. Key anthropogenic radionuclides (14C, 3H, 137Cs and 239,240Pu) were analysed. The 14C specific activity varied from 97.80 ± 1.30 to 102.40 ± 0.79 pMC. The 3H specific activity in the tissue-free water tritium form varied from 13.2 ± 2.2 TU to 20.8 ± 2.3 TU, which corresponded to the 3H level of precipitation in this region. The activity concentrations of 239,240Pu in soil and moss samples did not exceed 1 Bq/kg and were mainly due to global fallout after nuclear tests. The 137Cs inventory in the pine forest soils of the Lithuanian part of the BelNPP 30-km zone varied from 930 ± 70 to 1650 ± 430 Bq/m2. High variation of the inventory and uneven distribution in the soil profile conditioned a wide range of 137Сs activity in terrestrial plants from 1.0 ± 0.5 to 40.5 ± 1.8 Bq/kg dry weight. The abundance of microorganisms in different seasons and soil depths do not exceed the natural levels. According to PCA loads, the number of microorganisms and variability of 137Cs specific activity is determined by soil abiotic parameters.

Abstract
The application of more environmentally friendly hide and skin unhairing technologies in leather processing results in a significant increase in keratin waste. There are currently two most promising hair-saving unhairing methods: enzymatic and hair immunisation. The complete use of hair-saving unhairing methods in the leather industry will lead to the formation of approximately 143 thousand tons of hair/wool waste annually, which will require disposal. The disposal of keratin wastes from the leather industry has not been adequately studied, bearing in mind the possible amount of such wastes that will be produced in the future. Unfortunately, existing studies pay little attention to the method of unhairing, even though the unhairing method has a vast influence on the properties of keratin in the obtained hair/wool wastes. Accordingly, the present research is an attempt to establish how the differently obtained keratin wastes behave following disposal. The obtained results have shown that waste wool is characterised by different behaviour during burial in soil, and the behaviour depends on the method of unhairing. This proposition is valid for waste wool bioresistance as well. It was concluded that the deterioration of any sort of keratinous waste from the leather industry should be investigated thoroughly before disposal by burial in landfills.

Abstract
Invasive infections caused by drug-resistant bacteria are frequently responsible for fatal sepsis, morbidity and mortality rates. In this work, we propose a new methodology based on nanosecond high frequency electric field bursts, which enables successful eradication of bacteria in vivo. High frequency (15 kHz) 15–25 kV/cm 300–900 ns pulsing bursts were used separately and in combination with acetic acid (0.1–1%) to treat Pseudomonas aeruginosa in a murine model. Acetic acid 1% alone was effective resulting in almost 10-fold reduction of bacteria viability, however combination of nanosecond electric field and acetic acid 1% treatment was the most successful showing almost full eradication (0.01% survival compared to control) of the bacteria in the contaminated area. The short duration of the pulses (sub-microsecond) and high frequency (kHz range) of the burst enabled reduction of the muscle contractions to barely detectable level while the proposed applicators ensured predominantly topical treatment, without electroporation of deeper tissues. The results of our study have direct application for treatment of wounds and ulcers when chemical treatment is no longer effective.

Abstract
Treatment of bacteria-associated infections is complicated and antibiotic treatment alone is often inadequate to overcome biofilm infections. Physical methods allow overcoming this problem and propose solutions that are non-dependent on drug resistance. In this work, we investigated the feasibility of pulsed electric fields for sensitization of MRSA to common antibiotics. We analyzed the efficacy of inactivation of methicillin-resistant Staphylococcus aureus in 5–20 kV/cm electric field separately and in combination with gentamicin, doxycycline, ciprofloxacin, sulfamethoxazole, and vancomycin. Combined treatment allowed using up to 1000-fold smaller concentrations of antibiotics to induce the same inactivation of S. aureus.

Abstract
Although the nature-identical chemical compounds are cheaper, they not always repeat biological activity of plant origin natural chemical compounds, often react allergies and resistance of microorganisms. The aim of this study was to investigate effects of Juniperus communis origin α-pinene with different enantiomeric composition on bacteria, yeasts and fungi. Results showed that different enantiomeric composition of α-pinene have different activities on microorganisms: essential oil with (1S)-(-) ≈ (1R)-(+) enantiomeric composition of α-pinene influenced on some microorganisms stronger than essential oil with (1S)-(-) < (1R)-(+) enantiomeric composition of α-pinene; the pure natural α-pinene with enantiomeric composition S < R more strongly inhibited growth of investigated bacteria and Candida yeasts, α-pinene with enantiomeric composition S ≈ R - growth of Trichophyton and Aspergillus. (1S)-(-) and (1R)-(+) enantiomeric forms of α-pinene can have also different synergistic effects with other compounds of essential oil. The results of study showed that the same amount of α-pinene with different enantiomeric composition can have diverse antimicrobial potential due different specific interactions with other chemical compounds of essential oil. Therefore, it is very important to determine and present the enantiomeric composition of those plant origin compounds, which are characterized by enantiomerisation, during the course of research of biological activities of natural plant products (essential oils and other) and their isolated compounds.

Abstract
AIM Determine the influence of pH on the inactivation efficiency of Candida albicans in pulsed electric fields (PEF) and evaluate the possibilities for sensitization of a drug-resistant strain to antifungal drugs. MATERIALS & METHODS The effects of PEF (2.5-25 kVcm-1) with fluconazole, terbinafine and naftifine were analyzed at a pH range of 3.0-9.0. Membrane permeabilization was determined by flow cytometry and propidium iodide. RESULTS PEF induced higher inactivation of C. albicans at low pH and increased sensitivity to terbinafine and naftifine to which the strain was initially resistant. Up to 5 log reduction in cell survival was achieved. CONCLUSION A proof of concept that electroporation can be used to sensitize drug-resistant microorganisms was presented, which is promising for treating biofilm-associated infections.

Recently, a novel contactless treatment method based on high-power pulsed electromagnetic fields (PEMF) was proposed, which results in cell membrane permeabilization effects similar to electroporation. In this work, a new PEMF generator based on multi-stage Marx circuit topology, which is capable of delivering 3.3 T, 0.19 kV/cm sub-microsecond pulses was used to permeabilize pathogenic yeast Candida albicans separately and in combination with conventional square wave electroporation (8-17 kV/cm, 100 μs). Bursts of 10, 25, and 50 PEMF pulses were used. The yeast permeabilization rate was evaluated using flow cytometric analysis and propidium iodide (PI) assay. A statistically significant (P < 0.05) combinatorial effect of electroporation and PEMF treatment was detected. Also the PEMF treatment (3.3 T, 50 pulses) resulted in up to 21% loss of yeast viability, and a dose-dependent additive effect with pulsed electric field was observed. As expected, increase of the dB/dt and subsequently the induced electric field amplitude resulted in a detectable effect solely by PEMF, which was not achievable before for yeasts in vitro.

Abstract
CONTEXT The role of hypericin-mediated photodynamic antimicrobial properties on pathogenic fungi and photodynamic therapy for human cancer cells is known. Antifungal properties of Hypericum perforatum L. (Hypericaceae) and Fagopyrum esculentum Moench. (Polygonaceae) extracts were also studied. The different polarities of solvents can cause complication in the identification of antifungal effects of separate biologically active compounds. In recent experimental work, we compared antifungal properties of purified hypericin, hypericin tetrasulphonic acid (hypericin + S) and fagopyrin, which is analogue of hypericin. OBJECTIVE The antifungal properties of aromatic polyketide derivatives such as hypericin, hypericin + S and fagopyrin on the selected pathogenic fungi and spoilage yeasts have been studied. MATERIALS AND METHODS The antifungal properties of hypericin, hypericin + S and fagopyrin were determined using the broth microdilution method against a set of pathogenic fungi and spoilage yeasts including: Microsporum canis, Trichophyton rubrum, Fusarium oxysporum, Exophiala dermatitidis, Candida albicans, Kluyveromyces marxianus, Pichia fermentans and Saccharomyces cerevisiae. The tested concentrations of hypericin, hypericin + S and fagopyrin ranged from 750 to 0.011 μg/mL and MIC values were evaluated after 48 h incubation at 30 °C. RESULTS The results confirm different antifungal properties of hypericin, hypericin + S and fagopyrin on the selected pathogenic fungi and spoilage yeasts. For pathogenic fungi, the minimum inhibitory concentrations of hypericin ranged 0.18-46.9 μg/mL, hypericin + S 0.18-750 μg/mL and fagopyrin 11.7-46.9 μg/mL. For spoilage yeasts, the MICs of hypericin and hypericin + S ranged 0.18-46.9 and 0.011-0.73 μg/mL, respectively. DISCUSSION AND CONCLUSION The results obtained herein indicate that various chemical structures of hypericin, hypericin + S and fagopyrin can develop different antifungal properties.

Abstract
UNLABELLED Biofiltration is a method of biological treatment belonging to cleaner technologies because it does not produce secondary air pollutants, but helps to integrate natural processes in microorganisms for decomposing volatile air pollutants and solving odor problems. The birch wood biochar has been chosen as a principal material for biofilter bed medium. The experiments were conducted at the temperatures of 24, 28, and 32 °C, while the concentration of acetone, xylene, and ammonium reached 300 mg/m(3) and the flow rate was 100 m(3)/hr. Before passing through the stage of the experimental research into the packing material inside biofilters, microorganisms were introduced. Four strains of microorganisms (including micromycetes Aspergillus versicolor BF-4 and Cladosporium herbarum 7KA, as well as yeast Exophiala sp. BF1 and bacterium Bacillus subtilis B20) were selected. At the inlet loading rate of 120 g/m(3)/hr, the highest elimination capacity of xylene in the biochar-based biofilter with the inoculated medium was 103 g/m(3)/hr, whereas that of ammonia was 102 g/m(3)/hr and that of acetone was 97 g/m(3)/hr, respectively. The maximum removal efficiency reached 86%, 85%, and 81%, respectively. The temperature condition (though characterized by some rapid changes) can hardly have a considerable influence on the biological effect (i.e., microbiological activity) of biofiltration; however, it can cause the changes in physical properties (e.g., solubility) of the investigated compounds. IMPLICATIONS The birch biochar can be successfully used in the biofiltration system for propagation of inoculated microorganisms, biodegrading acetone, xylene, and ammonia. At the inlet loading rate of 120 g/m(3)/hr, the highest elimination capacity of xylene was 103 g/m(3)/hr, that of ammonia was 102 g/m(3)/hr, and that of acetone was 97 g/m(3)/hr, respectively. The morphological structure of biochar can be affected by the aggressive air contaminants, causing the change in the medium specific surface area, which is one of the factors controlling the biofilter performance. Although biological effects in biofiltration are typically considered to be more important than physical effects, the former may be more important for compounds with high Henry's Law coefficient values, and the biofilter design should thus provide conditions for better compound absorption.

Abstract
The dermatophytes infect the skin by adherence to the epidermis followed by germination, growth, and penetration of the fungal hyphae within the cells. The aim of this study was to investigate the efficacy of the pulsed electric fields (PEF) of controlled inactivation of Trichophyton rubrum (ATCC 28188). In this work, we have used bursts of the square wave PEF pulses of different intensity (10-30 kV/cm) to induce the irreversible inactivation in vitro. The electric field pulses of 50 µs and 100 µs have been generated in bursts of 5, 10, and 20 pulses with repetition frequency of 1 Hz. The dynamics of the inactivation using different treatment parameters were studied and the inactivation map for the T. rubrum has been defined. Further, the combined effect of PEF with the antifungal agents itraconazole, terbinafine, and naftifine HCl was investigated. It has been demonstrated that the combined effect results in the full inactivation of T. rubrum colony. © 2016 American Institute of Chemical Engineers Biotechnol. Prog., 32:1056-1060, 2016.

Abstract
Changes in the number and species diversity of cultivable microorganisms in a newly developed plate-type biofilter during filtration of various volatile pollutants were studied. The novelty of the investigation is the monitoring of microorganism succession in different parts of biofilter plates with original packing material consisting of birch fibre and needle-punched non-woven fabric. It was shown that the largest number of fungi and yeasts develop on the top and middle, while bacteria develop on the bottom and middle parts of plates. The number of microorganisms depends on the origin of the pollutant, the pH and temperature inside the biofilter and the moisture of the porous plates. The statistically significant correlation between the number of microorganisms and inlet concentration of acetone was estimated, while ammonia showed a negative influence on yeast distribution. Paecilomyces variotii, Rhodotorula mucilaginosa and Bacillus subtilis were the most common organisms found during filtration of all examined volatiles; however, some differences of microbial communities in different parts of the biofilter plates and filtrated volatile compounds were obtained.

Abstract
The aim of the investigation was to determine diversity of the causative agents of dermatophytoses and characterize the epidemiological situation in Lithuania in 2001-2010. During this period, dermatophytes showed a tendency to decline. The following dermatophytes were isolated: Trichophyton (T.) Malamsten, Microsporum (M.) Gruby and Epidermophyton E. Lang. The number of nondermatophytes increased. At the beginning of the investigation, nondermatophytes accounted for 3.4%, whereas at the end their number grew up to 35.9%. Among the agents of dermatomycosis, the incidence of yeasts was observed to have a growing tendency. Among dermatophytes, T. rubrum was the most common pathogen, which in 2001 amounted to 55.7% and in 2010 to only 11.0%. Among the Microsporum species, M. canis and M. gypseum were detected. A small number of Epidermophyton species were observed in 2001-2003, which accounted for 0.2%-0.8% of all isolates. Tinea unguium (75.5%) was the most common type of dermatophytosis, followed by tinea capitis (11.7%), tinea corporis (9.2%) and tinea pedis (1.2%). In 2001-2010, dermatophytes showed a decreasing tendency, whereas the incidence of Candida yeasts and other causative agents of dermatomycosis greatly increased.
