of basidiomycetes class belongs to a group known as â€œwhite rot fungiâ€ as they produce a white mycelium and are generally cultivated on non-composted lignocellulosic substrates 15,69. Mushrooms are a rich source of nutrients, particularly proteins, mineral vitamins as well as bioactive constituents, such as phenolic compounds, terpenes, steroids and polysaccharides 39,61,62. Asimismo, es de interÃ©s para la RAM la publicaciÃ³n de artÃculos de impacto regional. Con la finalidad de incluir los aspectos bÃ¡sicos de la investigaciÃ³n en el Ã¡rea, la Revista tambiÃ©n considera para su publicaciÃ³n trabajos sobre genÃ³mica, proteÃ³mica y enzimologÃa de microorganismos y parÃ¡sitos. La RAM tambiÃ©n publica artÃculos sobre ecologÃa microbiana y diversidad, zoo y fitopatÃ³genos y sobre microorganismos de interÃ©s alimentario, agrÃcola, industrial y ambiental. Los temas de interÃ©s especial incluyen las infecciones causadas por bacterias, hongos, parÃ¡sitos, virus y agentes infecciosos no convencionales, mecanismos de patogenicidad, factores de virulencia y respuesta inmune asociada a los agentes infecciosos, resistencia a los agentes antimicrobianos, taxonomÃa, epidemiologÃa y mÃ©todos diagnÃ³sticos fenotÃpicos, inmunolÃ³gicos y moleculares, entre otros. The spent block may be composted or used to inoculate a new substrate.La Revista Argentina de MicrobiologÃa es una publicaciÃ³n trimestral editada por la AsociaciÃ³n Argentina de MicrobiologÃa y destinada a la difusiÃ³n de trabajos cientÃficos en las distintas Ã¡reas de la MicrobiologÃa y la ParasitologÃa. After a few flushes, the substrate no longer contains enough nutrients.Make incisions over primordia that may have formed in other places under the bag. Drain excess water and put it back in the container. If it seems too dry it can be submerged or rinsed with water. In between harvests, the mycelium may benefit from a period of rest without humidity, in the fridge. Under ideal conditions, up to ½ of the block’s initial weight may be harvested over several flushes. If left longer they will drop their spores and begin to degrade. The mushrooms will be ready to harvest once the edge of the caps start to slightly unfurl.In this case, remove all dried mushrooms from their point of attachment and let the block reproduce new primordia. If they crack, start yellowing or stagnate, it is a sign they have dried out. If the caps stay small and the stems elongate and twist in several directions, it is a sign the mushrooms lack oxygen. Make sure to vent out the accumulated CO 2.

Every day, lightly mist the interior surfaces of the container with water.Below are the ideal fruiting temperatures for the oyster mushrooms:īlue, white and Grey Oyster Mushrooms: 10-20☌ Depending on the species, the ideal temperature for primordia formation may vary. Then place the bag in the container, making sure not to submerge the opening you made in step 1. To provide a source of moisture, either pour water in the bottom of your fruiting container or place a bowl of water inside it.If primordia have already appeared on the top of the block, carefully cut off the top of the plastic bag instead of making an “X” in the side. Then fold down the top (empty part) and hold it in place with tape or an elastic. Once ready to grow your mushrooms, make an “X”-shaped incision about halfway up the bag taking care not to damage the mycelium.The container may be perforated and/or left partially open and should be ventilated a few times a day. Mushrooms require oxygen to grow correctly and they produce a large amount of CO 2, especially while fruiting. A small grow tent, a plastic tote box, an aquarium, a terrarium or even a plastic bag large and rigid enough to create a dome are all viable options. This step is important to ensure the development of the primordia (budding mushrooms) into mature mushrooms. See the table below for ideal fruiting temperatures.īefore fruiting the block, it is important to create an appropriate environment to maintain 85% relative humidity. However avoid direct sunlight and constant air streams as they will tend to dry out the mushrooms ambient light or fluorescent lighting at a distance of at least 3 metres is enough. In order to fruit, oyster mushrooms require light, humidity and fresh air. Once fully colonised, keeping the bag closed in the fridge will slow down its growth and postpone fruiting. The grow bag contains a block composed of mushroom mycelium, a mix of sawdust, straw and wheat bran (which nourish the mushrooms), grain and water.
