Abstract White rot fungi (WRF) are known to have the ability to degrade organic pollutants with a structure similar to lignin. Because of this, the degradation of polychlorinated biphenyls (PCBs) congeners no. 28, 52, 101, 138, 153 and 180 by substrate before fruiting (substrate) and/or after fruiting (SMS) from cultivated mushrooms Pleurotus ostreatus, Lentinula edodes and Agaricus bisporus was examined. The experiment was carried out in four replications for each treatment using a mixture of substrate/SMS and sandy soil with PCBs at a concentration of each congener at 50 and 100 μg kg−1 soil DW. The results indicate that degradation was dependent on substrate/SMS addition, the concentration of PCBs and time of incubation. The efficiency of PCB degradation was generally reduced with the number of chlorine atoms in the structure of congeners: 28, 52, 101, 138, 153 or 180. In all combinations, degradation increased with incubation time. Degradation by SMS was lower in comparison to degradation by a substrate of the same mushroom. The degree of degradation of a single PCB after 12 weeks of incubation for A. bisporus ranged from 31.32 ± 1.52 to 83.91 ± 1.07%, while for P. ostreatus it was between 37.88 ± 2.54 and 78.29 ± 1.41%; for L. edodes it ranged from 17.38 ± 1.06 to 75.30 ± 1.46%. The best average degradation was confirmed for 20% SMS of A. bisporus at 50 μg kg−1 PCB.

O consumo de cogumelos no Brasil expandiu-se fortemente com o boom dos restaurantes orientais e, embora ainda não faça parte da dieta da maioria da população brasileira, o interesse dos consumidores pelos cogumelos é crescente. Os principais cogumelos produzidos no Brasil são o champignon de Paris (Agaricus bisporus ou bitorquis), o shiitake (Lentinula edodes), o shimeji (Pleurotus ostreatus) e o hiratake (Pleurotus sajor caju). A produção brasileira de cogumelos não é capaz de suprir a demanda, sendo necessária a importação do produto de outros países para abastecer o mercado interno, indicando que há espaço para o incremento da produção. Aliado a isso, o cultivo de cogumelos pode ser realizado em áreas pequenas, sendo uma importante complementação de renda para pequenos produtores da agricultura familiar. A produção de cogumelos já uma realidade na região de Londrina – PR que atende o mercado local e regional, no entanto, ainda não há uma caracterização desta atividade na região. O objetivo deste trabalho é levantar experiências locais de produção de cogumelos e apontar principais desafios e potenciais oportunidades para a produção na região. Para isso, um questionário foi aplicado a alguns produtores, levantando informações como principais espécies de cogumelos produzidas, sistema produtivo adotado, destino de comercialização, entre outros. Os resultados indicaram que a fungicultura na região é recente e ainda pouco organizada. Os principais obstáculos apontados pelos produtores foram a falta de assistência técnica, a necessidade de importação de insumos de outros estados e a concorrência com os preços dos cogumelos de São Paulo.

Many studies highlight the health benefits of mushrooms, which are consequently becoming more and more interesting for researchers. The content of amino acids (AA), total phenolic content (TPC), and antioxidative activity (AAc) were determined in wild as well as cultivated mushrooms. The AA included: L-tryptophan (Trp), L-arginine (Arg), L-cysteine (Cys), L-methionine (Met), L-alanine (Ala), L-phenylalanine (Phe), L-lysine (Lys), L-valine (Val), L-glycine (Gly), and L-leucine (Leu). The wild mushrooms: Lactarius piperatus, Amanita caesarea, Lactarius deliciosus, Lycoperdon pyriforme, Macrolepiota procera, and cultivated mushrooms: Agaricus bisporus, Boletus aestivalis, Cantharellus cibarius, Pleurotus ostreatus, and Agaricus bisporus var. avellaneus were investigated in this study. The AA was determined by HPTLC method and quantified with a Camag TLC scanner and WINCAT software by scanning the plates at 540 nm. The TPC was spectrophotometrically estimated as gallic acid equivalents/g of fresh weight according to Folin-Ciocalteu’s method. The radical scavenging activity (RSA) of mushroom extracts was determined by DPPH assay. The highest content of Ala, Gly, Phe, Lys, Val, and Leu was found in Pleurotus ostreatus. The total phenolic content (mg GAE/g) in investigated mushrooms ranged from 1.90 to 35.56, and the % RSA ranged from 43.88 to 90.17. This study promotes the consumption of food rich in bioactive compounds, mushrooms being among such food. Further research on mushrooms from Bosnia and Herzegovina and their benefits in the overall maintenance of human health and protection from age-related diseases is necessary.

In this study, the microbiological and sensory quality of cultivated mushrooms (Pleurotus ostreatus and eryngii and Lentinula edodes) available at the Austrian retail level were determined. Aerobic mesophilic bacteria (AMC), Enterobacteriaceae (EB), Pseudomonadaceae (PS), lactic acid bacteria (LAB), yeast, moulds and presumptive Bacillus cereus were enumerated at the day of purchase and after storage at 4 °C for 7 or 12 days. Additionally, the presence of Salmonella spp. and Listeria monocytogenes was investigated. Isolates of presumptive spoilage bacteria were confirmed by partial 16S rRNA sequencing. At the day of purchase, 71.2% of the samples were of high microbiological quality and grouped into the low contamination category (AMC < 5.0 log cfu/g), while the sensory quality of 67.1% was categorized as “very good or good”. After storage, the number of samples with high microbial quality was 46.6%, and only 37.0% of the samples scored as “very good or good”. The most abundant species across all mushroom samples were the Pseudomonas fluorescens species complex (58.4%) and the potential mushroom pathogen Ewingella americana (28.3%). All mushroom samples tested negative for Salmonella spp., L. monocytogenes and Bacillus cereus. The microbiological and sensory quality of the analysed mushrooms at the day of purchase and after storage was considered to be good overall. Longer transport distances were found to have a significant influence on the microbiological and sensory quality.
