Adaptation strategies in haloalkaliphilic fungi: Aspergillus salinarum, cladosporium sphaerospermum, and penicillium camemberti.
Article in BMC microbiology, 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
backgroundExtremophilic fungi thrive in extreme environments, revealing life's origins and enhancing biodiversity while offering insights into evolutionary biology. This study investigates the adaptation mechanisms of haloalkaliphilic fungi Aspergillus salinarum, Cladosporium sphaerospermum, and Penicillium camemberti, isolated from Egyptian soils, adapted to life under extreme conditions of high salt (15%) and alkaline pH (10). These properties make them interesting for fundamental research and the exploration of biotechnological potential.
resultsThese fungi exhibited increased levels of soluble proteins and lipids in cell-free extracts under stress conditions. Enzyme activities, specifically peroxidase and tyrosinase, were significantly induced, with maximum induction varying by species and incubation time. Significant amounts of organic acids, including citric, oxalic, and butyric acids, were detected in higher quantities under extreme conditions, with total organic acid content increasing by up to 2.97%. The culture filtrates demonstrated enhanced antimicrobial activity against various Gram-positive and Gram-negative bacteria, Bacillus Subtilis (ATCC 6633); Staphylococcus aureus (ATCC 6538); Escherichia coli (ATCC 8739); Pseudomonas aeruginosa (ATCC 90274); yeast, Candida albicans, but not against Aspergillus niger.
conclusionsThese findings highlight the potential industrial applications of these fungi in biotechnology and pharmaceuticals due to their biochemical responses and antimicrobial properties.
