“…Thus, treatment of substrates using hot water can be effective in producing mushrooms in rural areas (Akhter; Chowdhury; Aminuzzaman, 2017) if it is wellexecuted and raw materials are used appropriately. Other alternatives to the autoclaving system are composting or pasteurization; these methods have provided good results in the cultivation of mushrooms at a lower cost (compared to autoclaving) and without eliminating beneficial microorganisms present in the substrate (Gowda;Manvi, 2019). The choice of the substrate used in mushroom cultivation is extremely important since it influences the centesimal composition of the mushrooms and allows the optimization of production according to the desired nutritional characteristics.…”

“…Substrate treatments include conventional methods, such as thermal (pasteurization with hot water or steam) and chemical disinfection (with formaldehyde, carbendazim, chlorine, hydrogen peroxide, and calcium hydroxide) (Rodriguez;Pecchia, 2017;Gowda;Manvi, 2019). Although they are not effective in the complete elimination of antagonistic microorganisms, they reduce the level of microorganisms sufficiently for cultivation (Dias, 2010).…”

One of the most expensive steps in mushroom production is the disinfection of the substrate. This study aimed to evaluate different methods of disinfecting various substrates used in the cultivation of Pleurotus ostreatus from the Amazon. P. ostreatus was grown under uncontrolled temperature conditions in a greenhouse (at approximately 30 °C) on substrates formulated with residues (seeds) of açaí and tucumã palm trees, Brazil nuts shell and pine sawdust. The different substrate disinfection treatments comprised autoclaving, immersion in hot water or immersion in calcium hydroxide (2%). The chemical composition of residues, substrates, and mushrooms was analyzed. During cultivation, it was found that in the treatment with hot water, all the bags were contaminated, and treatment with calcium hydroxide inhibited the colonization and growth of the mushrooms. P. ostreatus grown on the autoclaved açaí substrate supplemented with tucumã had higher production. The highest percentage of fiber content was obtained when the mushrooms were cultivated in the pine substrate supplemented with Brazil nuts (32.68 to 33.65%), and the highest protein content (20.03 to 20.88%) was found in the mushrooms grown on açaí-based substrates. Considering that P. ostreatus showed higher productivity in autoclaved substrates, further studies should be performed to develop alternative methods of disinfecting substrates for the cultivation of mushrooms in the Amazon region, as well as, in other regions with a tropical climate. However, the cultivation of this mushroom is promising using some regional substrates, especially with açaí, which is one of the important natural products of the Amazon.

“…Ideally, all seeds, nematodes, insects, and other organisms that thrive at the temperatures used to grow the mushrooms must be killed by the efficient procedure [14]. Steam sterilization, immersion in hot water, and chemical treatment methods are described in the oyster mushroom cultivation protocol [15]. However, very few studies have been published in the literature to evaluate the efficacy of these sterilization methods that influence mushroom's quality and quantity [16].…”

Due to their excellent flavour and taste, Pleurotus species, which flourish in temperate and subtropical environments, are well-liked among edible mushrooms. Oyster mushrooms could be grown on a variety of substrates due to their powerful enzymatic properties. Pleurotus sp. grows more easily, more profitably, and more nutrient-densely on a variety of organic waste raw materials and environmental factors. Sterilization of the substrate is one of the most crucial steps in oyster mushroom cultivation. There have been numerous reports of contaminated mushroom substrate. Suitable sterilization techniques must be used on the substrates. There are several treatments for mushroom substrate that can be used to manage the frequent moulds that infest edible mushrooms. Sterilization of the substrate is necessary to get rid of pathogenic and rival microorganisms and to encourage the mycelial growth of the desired mushroom species. The goal of the current study was to identify the best treatment strategy for the chosen substrates. For substrate treatment for Pleurotus florida cultivation, hot water, boiling water, steam sterilization in an autoclave, and chemical treatment methods were used. It was observed that the steam sterilization method was superior to other methods as it supported relatively short spawn run duration, amazing yield, and high biological efficiency.

“…Media sterilization is one of the most important processes in the cultivation of oyster mushrooms because the media that has been made usually still contains many microbes, especially wild mushrooms [7]. Conventional sterilization is generally carried out for 8 hours at a temperature of 70-95 o C [8]. Oyster mushroom cultivation of them, can be done with a steam technique using the drum.…”

Implementation of proportional–integral control in Baglog steamer temperature control

Sterilization is the oyster mushroom cultivation process. Sterilization is used to kill nuisance microorganisms that can inhibit mushroom growth. The sterilization process is 8 hours at a temperature of 70–95 oC. This process of frequent breakdown is caused by the unstable temperature sterilization space and is controlled manually. Based on these problems, the right solution is to use a steamer that can be controlled automatically using the proportional–integral (PI) control method. PI controller consists of proportional gain and integral gain. To determine the value of proportional gain and integral gain, this study used the Ziegler-Nichols tuning method using the S curve. The results of the PI control parameters obtained the value of Kp=25.2 and Ki=0.302. Thus, producing a transient response graph with Mp=94.5; Os=0.45; PO=0.47; Tr=16,440 s. The system can work according to setpoint 95 oC and maintain a stable temperature according to the setpoint with these results. And the sterilization time becomes fast from 8 hours to 6 hours.
