Microbiota and quality profiling of fermented goat meat sausages (sucuk) under nitrite-reduced and mixed-culture strategies.
Article in World journal of microbiology & biotechnology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 bioprotective activity of lactic acid bacteria (LAB) to modulate the microbiota and quality of nitrite-reduced fermented goat meat sucuk was investigated. Antagonistic activity of LAB strains against foodborne pathogens was evaluated using agar well diffusion, spot-on lawn, and cross-streak assays. Three LAB isolates affiliated with the genera Weissella, Limosilactobacillus, and Lactiplantibacillus, exhibiting inhibition zones > 18 mm, were selected and applied as a mixed culture (MC; 2:1:1). Sucuk formulations with 150, 75, and 0 ppm sodium nitrite were produced in the presence or absence of a MC and analyzed during fermentation (days 0 and 7) and refrigerated storage (days 7 and 14). Among the treatments, 75 ppm nitrite combined with MC (75-MC) exhibited the highest LAB counts, enhanced acidification (pH 4.7 on fermentation day 7), inhibited pathogens and spoilage microorganisms, and improved moisture and color stability (> 90% of initial L* and a*), with a significant treatment × day interaction (P < 0.05). Metagenomic analysis of the 16 S rRNA (V3–V4) and ITS2 regions revealed a LAB-dominated sucuk microbiota, characterized by Levilactobacillus (69.5%), Lactiplantibacillus (12.1%), Psychrobacter (8.8%), and Lacticaseibacillus (3.0%) among bacteria, and Yarrowia (46%), Kurtzmaniella (11.8%), Geotrichum (6.7%), and Cladosporium (5.5%) among fungi. This microbial composition was associated with enhanced microbial stability and technological quality, while mixed-culture strategies under nitrite-reduced conditions promoted a Lactobacillaceae-enriched microbiota, highlighting their potential role in bioprotection and product quality.
