“…The fertility parameter of individual strains may be significant, as there is evidence that the biological efficiency of individual strains may vary [ 62 , 63 , 64 ]. Pleurotus ostreatus species is quite unique because they are able to grow on different agrowaste materials [ 65 ], such as rice straw [ 66 ], oil palm fronds [ 67 ], empty fruit bunch and palm-pressed fiber [ 68 ], sugarcane bagasse [ 69 ], corn cob [ 70 ] wheat straw, coffee waste, and leaf litter of forest trees [ 71 ]. If the strain is characterized by a high content of β-glucans but is low in crop, it is not an important source of biologically valuable substances for the producer.…”

Oyster mushroom (Pleurotus ostreatus) is still one of the most cultivated edible and medicinal mushrooms. Despite its frequent cultivation around the world, there is currently just a little information available on the variability of strains in terms of the content of β-glucans in them. This work presents an extensive study of 60 strains in terms of the content of α-glucans and β-glucans in their caps and stipes. The authenticity of the production strains based on an analysis of the variability of their genome by CDDP (Conserved DNA-derived polymorphism) markers was confirmed, whereas identical CDDP profiles were identified between samples 45, 89, 95, and 96. Genetic variability of the analyzed production strains showed a high polymorphism and effective discriminative power of the used marking technique. Medium positive correlations were found among the CDDP profiles and β-glucan content in the group of strains that generated the same CDDP profiles, and low negative correlation was found among these profiles in the group of low β-glucan content strains. For the determination of glucans content, Mushroom and Yeast analytical enzymatic kit (Megazyme, Bray, Co. Wicklow, Ireland) were used. The results clearly showed that the stipe contains on average 33% more β-glucans than the cap. The minimum detected β-glucan content in the stipe was in strain no. 72, specifically 22%, and the maximum in strain no. 43, specifically 56%, which after the conversion represents a difference of 155%. From the point of view of β-glucan content, the stated strain no. 43 appears to be very suitable for the commercial production of β-glucans under certain conditions.

“…Before planting (inoculation) seeds into the planting medium, it is necessary to prepare tools and materials. Then sterilize at a predetermined temperature [14]. The materials used in the activity are gleam wood sawdust, rice bran, corn bran, agricultural lime (CaCO3), oyster mushroom seeds, gypsum, 70% alcohol, and spirit [15].…”

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.

“…High protein content of 21.56 % in tofu dregs indicates that the nitrogen content is also high so that the growth of mycelium becomes thick and compact ( Table 2). Tofu waste contains carbohydrates, protein, fat, minerals and vitamins [7]. added that protein functions to stimulate mycelium growth.…”

Brown oyster mushroom is one of the consumption mushrooms with high economic value, so it is important to be cultivated commercially. Several types of plant and industrial wastes, such as dried banana leaves and tofu dregs, are available abundantly in the field. The waste has the potential to be used as medium for growing consumption mushrooms. This is because dried banana leaves and tofu dregs contain enough nutrients needed for the growth and development of oyster mushrooms. The study aimed to determine the growth response and yield of brown oyster mushrooms by giving various doses of dried banana leaves and tofu dregs flour. The research was carried out using factorial completely randomized design. First factor: dosage of tofu flour: 50 g per baglog, 150 g per baglog, and 250 g per baglog. Second factor: dosage of dried banana leaves, without dried banana leaves, 100 g dried banana leaves per baglog, and 250 g dried banana leaves per baglog. The results showed that the treatment of addition of tofu dregs flour with dried banana leaves interacted very significantly in the number of mushroom caps, diameter and thickness of the caps, the length of the mycelium, the fresh weight of the fungus, and biological efficiency.
