1 · What the graph read from it

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.

2 · The registry

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

purposesThe objective of this study was to assess the potential of yeast Pichia kudriavzevii (NUNS-4, NUNS-5, NUNS-6, and TISTR5147) and Saccharomyces cerevisiae TISTR5606 strain to utilize banana, Musa ABB cv. (Kluai Namwa) and Musa sapientum L. cv. (Kluai Khai), biomass through the co-production of single cell protein and ethanol.

resultsAll tested strains grew well on both YPD and banana-based agar, confirming that banana residues can sustain yeast growth. Supplementation with banana biomass significantly enhanced protein and carbohydrate content. Notably, P. kudriavzevii TISTR5147, P. kudriavzevii NUNS-6, and S. cerevisiae TISTR5606 exhibited the highest single cell protein levels (50.85 ± 1.73%, 49.13 ± 1.50%, and 46.96 ± 1.07%, respectively) using Kluai Namwa, compared to controls without banana substrate. Ethanol yields were also increased when banana biomass was included. Co-fermentation of ripe pulp Kluai Khai with YPD resulted in the highest ethanol yields, reaching 77.63 ± 3.11 g/L for P. kudriavzevii NUNS-6, followed by 76.57 ± 4.49 g/L for NUNS-5, 74.17 ± 2.21 g/L for NUNS-4, and 72.32 ± 1.63 g/L for TISTR5147. Therefore, P. kudriavzevii NUNS-6 demonstrated superior efficiency as a dual producer of single-cell protein and ethanol.

conclusionThese findings demonstrate that banana biomass is a cost-effective and sustainable carbon source for single-cell protein and ethanol production. Moreover, the P. kudriavzevii NUNS strains exhibited strong potential for bioconversion of banana residues into high-value products, supporting their applicability in future large-scale biotechnological processes.
