Highlighting the Potential of an Amazonian Oyster Mushroom (Pleurotus Ostreatus) through Comparison with Commercial Strains: Mycelial Growth and Protease Production in Different Culture Media.
Article in Applied biochemistry and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The Amazon biome hosts a rich fungal biodiversity; however, the biotechnological potential of its macrofungi remains largely underexplored. This study evaluates and compares the mycelial growth and protease production of a wild Amazonian isolate of Pleurotus ostreatus (474) with two commercial strains (542 and 885) to identify unique biotechnological profiles. The strains were cultivated in nine different culture media, and their mycelial growth rates and major proteolytic activities were systematically measured. The wild Amazonian strain (474) exhibited significantly superior mycelial growth, reaching maximum growth on Oat Flakes Agar (OFA) within four days. In contrast, the commercial strains acted as specialized enzyme producers; strain 885 showed the highest cysteine protease activity (8.05 ± 0.15 UA/mL) on Malt Yeast Sucrose Agar (MYSA), while strain 542 exhibited the highest total protease (77.53 ± 0.67 UA/mL) and fibrinolytic activity (6.45 ± 0.00 mm²) on Malt Extract Agar (MEA). These results reveal a clear biotechnological trade-off, with the Amazonian isolate excelling in biomass accumulation and the commercial strains optimized for enzyme production. This study highlights the Amazonian strain as a promising candidate for rapid mycoprotein production and underscores the Amazon as a valuable source for expanding the functional diversity of P. ostreatus.
