Megjegyzések:	The Pleurotus ostreatus (oyster mushroom) play an important role in improving and balancing gut microbiota composition. The objective of this study is to investigate the impact of mushroom liquid-based solid media on the growth rate and morphology of P. ostreatus, aiming to develop a feed supplement that contains a huge amount of antimicrobial and prebiotic agents. To prepare the media, raw mushrooms were appropriately washed, sliced, and placed in a sealed pressure cooker. The pressure cooker was then kept in a drying cabinet at 90?0.1 ?C for 24 hours. After 4 hours, the pressure cooker was removed from the drying cabinet. The solid and liquid fractions were separated using a centrifuge (1200 rpm for 8-10 minutes), then the final liquid was characterized by spectrophotometric and ICP-OES methods. Medias with various concentrations were prepared by combining oyster mushroom liquid with 0%, 25%, 50%, and 75% distilled water (LGA). The growth rate and morphology of P. ostreatus mycelia on different solid media, including its own liquid in different dilutions and A. bisporus mushroom liquid-based solid media (CSGA) without dilution, as well as Malt extract media as a control, were determined. Autoclaving (121 ?C, 20 minutes, 1.5-2.0 bar) and the mycelia transfer were carried out next to aseptic conditions. Based on the spectrophotometric measurements, the average values of DPPH were found to be 27.53?7.14 SC%, the total polyphenol content was 98.87?21.19 mg GAE/100 g, and the flavonoid content was 9.94?12.90 mg CE/100 g for the original matter. The average values of Ca (89.9?17.6 mg/l), K (1947?150.2 mg/l), Mg (105.6?9.9 mg/l), Na (49.6?4.1 mg/l), and P (424.4?66 mg/l) for the original matter were determined using ICP-OES analysis. The density of mycelia colonized in 100% oyster liquid media was the highest and most compact, while the colony grown on MEA agar was significantly less dense. Whole colonization was achieved within 6 days on LGA and MEA. However, it took an additional 8 days to utilize the nutrients from A. bisporus liquid-based media. According to the results, it can be said that the best media for mycelial growth is its own liquid. However, further studies are required to identify the most optimal and cost-efficient method for producing mycelia with increased bioactivity and develop effective feed supplements.
