Pleurotus ostreatus fungus forms an edible mushroom that possesses important nutritional and medicinal properties. Selenium (Se) is essential to human diets it in low concentration the soil, consequently food. P. was grown coffee husks enriched with various concentrations of sodium selenite. The biological efficiency affected by addition high Se. highest level Se absorption obtained adding 51 mg kg1 mushrooms from first flush contained more than further flushes. These results demonstrate...

The majority of the textile dyes are harmful to environment and potentially carcinogenic. Among strategies for their exclusion, treatment dye contaminated wastewater with fungal extract, containing lignin peroxidase (LiP), may be useful. Two fungi isolates, Pleurotus ostreatus (PLO9) Ganoderma lucidum (GRM117), produced enzymatic extract by fermentation in lignocellulosic residue, Jatropha curcas seed cake. extracts from PLO9 GRM117 were immobilized on carbon nanotubes showed an increase 18...

Growing concerns regarding the impact of accumulation plastic waste over several decades on environmental have led to development biodegradable plastic. These plastics can be degraded by microorganisms and absorbed environment are therefore gaining public support as a possible alternative petroleum-derived plastics. Among developed plastics, oxo-biodegradable polymers been used produce bags. Exposure this ultraviolet light (UV) or heat lead breakage polymer chains in plastic, resulting...

The mushroom Pleurotus ostreatus has nutritional and medicinal characteristics that depend on the growth substrate. In nature, this fungus grows dead wood, but it can be artificially cultivated agricultural wastes (coffee husks, eucalyptus sawdust, corncobs sugar cane bagasse). degradation of involves some enzyme complexes made up oxidative (laccase, manganese peroxidase lignin peroxidase) hydrolytic enzymes (cellulases, xylanases tanases). Understanding how these work will help to improve...

In recent years, several studies have been developed to understand the impact of fermentation on final quality coffee and indicated that postharvest processing could be a determinant quality. However, trend has appeared as scientific counterpoint, indicating interactions between soil, fruit, altitude, slope exposures with respect Sun are important behavior microbiome in coffee. Studies microbiota addressed its role during process, however knowledge indigenous microorganisms harbored fruits...

Agroecology aims to maintain ecosystem services by minimizing the impact of agriculture and promoting use biological potential. Arbuscular mycorrhizal fungi (AMF) are elements which key improving crop productivity soil quality. It is pertinent understand how agricultural management in tropics affects AMF spatio-temporal community composition, especially crops global importance, such as coffee (Coffea arabica L.). Soil root samples were collected from three localities under systems...

To initiate a conservation program of the Orchidaceae from Brazilian Atlantic rain forest with purpose ex situ or reintroduction in State Minas Gerais, seven mycorrhizal Rhizoctonia-like fungal strains were isolated roots neotropical orchid species three different fragments. Taxonomic studies revealed that isolates belong to genera Ceratorhiza and Epulorhiza. The Epulorhiza identified as repens (N. Bernard) R.T. Moore epiphytica Pereira, Rollemberg et Kasuya. RAPD analysis indicated higher...

Fungos micorrízicos arbusculares (FMAs) são fungos de solo, biotróficos obrigatórios e formadores da simbiose mutualista mais comum na natureza: a micorriza arbuscular (MA). Essa associação ocorre nas raízes maioria das plantas terrestres, promovendo melhorias no crescimento, desenvolvimento aumento tolerância e, ou, resistência vários agentes ambientais adversos. Além disso, os FMAs podem ser utilizados como potenciais controle biológico doenças plantas. Esses produzem ainda glomalina, uma...

The capability of Pleurotus ostreatus mushroom to accumulate lithium (Li) and the accessibility this Li compared with carbonate (Li2CO3), often used as psychiatric medicine, were investigated. Mushrooms produced on a substrate-based coffee husk, different added concentrations chloride (LiCl). Biological efficiency (BE), crude protein content, concentration other elements present in mushrooms determined. sequential extraction vitro test verify degree solubility element. was directly...

Approximately 10% of vascular plants are epiphytes and, even though this has long been ignored in past research, able to interact with a variety fungi, including mycorrhizal taxa. However, the structure fungal communities on bark, as well their relationship epiphytic plants, is largely unknown. To fill gap, we conducted environmental metabarcoding ITS-2 region understand spatial bark tropical trees, focus orchid and tested influence root proximity. For all guilds, were more similar when...

Abstract Brazilian coffee production relies on the cultivation of Coffea arabica and canephora . Climate change has been responsible for decreasing yield crops in country yet associated microbial community can mitigate these effects by improving plant growth defense. Although some studies have tried to describe microorganisms with species, a study that compares microbiome wider spatial scale is needed better understanding terroir each planting region. Therefore, our aim was evaluate...

The antibacterial activity of 35 isolates Lentinula edodes, a shiitake mushroom, against Bacillus subtilis was evaluated by diffusion technique in agar with semi-solid overlay. All inhibited B. and the isolate Le1 promoted formation largest inhibition zone. L. edodes also presented foodborne pathogens food contaminant bacteria, particularly Gram-positive species. culture filtrate after 18-25 days cultivation broth at 25ºC high. inhibitory observed only organic layer when partitioned between...

In this study, we evaluated the growth of Pleurotus ostreatus PLO6 using oxo-biodegradable plastics as a carbon and energy source. Oxo-biodegradable polymers contain pro-oxidants that accelerate their physical biological degradation. These were developed to decrease accumulation plastic waste in landfills. To study degradation polymers, bags exposed sunlight for up 120 days, fragments these used substrates P. ostreatus. We observed treatment alone was not sufficient initiate Instead,...

Some nematophagous fungi control nematodes and are also able to compensate the damage they cause in plant roots. However, effects of these on growth promotion still underexplored. Here, we evaluated if some nematophagus (Pochonia chlamydosporia Duddingtonia flagrans) may increase nutrient bioavailability promote growth. A chamber assay a greenhouse study (both without nematodes) were carried out assess phosphorus uptake by tomato plants. The use P. D. flagrans substantially increased...
