Initial pH determines the morphological characteristics and secondary metabolite production in Aspergillus terreus and Streptomyces rimosus cocultures.

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 influence of the initial pH on the morphology and secondary metabolite production in cocultures and axenic cultures of Aspergillus terreus and Streptomyces rimosus was investigated. The detected secondary metabolites (6 of bacterial and 4 of fungal origin) were not found in the cultures initiated at pH values less than or equal to 4.0. The highest mean levels of oxytetracycline were recorded in S. rimosus axenic culture at pH 5.0. Initiating the axenic culture at pH 5.9 led to visibly lower product levels, yet the presence of A. terreus reduced the negative effect of non-optimal pH and led to higher oxytetracycline titer than in the corresponding S. rimosus axenic culture. The cocultivation initiated at pH 5.0 or 5.9 triggered the formation of oxidized rimocidin. The products of A. terreus were absent in the cocultures. At pH 4.0, the striking morphological differences between the coculture and the axenic cultures were recorded.
