AI Article Synopsis
- Soil yeasts have beneficial effects on plants, such as promoting growth, solubilizing phosphate, and oxidizing nitrogen and sulfur, but are still not well-researched.
- This study aimed to evaluate the performance of soil yeasts for improving soil quality, identifying sixteen isolates with plant growth-promoting traits.
- After soil incubation with the selected yeast isolates, significant improvements in soil properties were noted, particularly with the isolate Pichia kudriavzevii showing the best results.
Article Abstract
Soil yeasts exhibit an array of beneficial effects to plants viz., plant growth promotion, phosphate solubilization, nitrogen and sulphur oxidation, etc. Yeasts remain as poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive/chemically novel compounds and potential bioinoculants. Hence this study holds the key concept of assessing the performance of soil yeasts with potential plant growth promoting ability in soil quality improvement. Sixteen soil yeast isolates with plant growth promoting traits were assessed for biofilm forming potential and five potential soil yeast isolates were selected and identified through molecular technique. Soil incubation study was performed with these isolates to assess their impact on soil physical, chemical and biological properties. Due to inoculation of soil yeasts, notable changes were observed in soil physical, chemical and biological properties. Among the soil yeast isolates, Pichia kudriavzevii gave better results in soil incubation study.

Cadmium (Cd) is one of the most dangerous environmental pollutants and is easily absorbed by food crops. Quinoa is a kind of coarse grain crop with rich nutrition and strong stress resistance, which is easy to accumulate Cd. The increasingly serious soil Cd pollution poses a serious threat to the food safety of quinoa.

Recently we demonstrated that the seed microbiome of certain spinach (Spinacia oleracea) seed lots can confer disease suppression against Globisporangium ultimum damping-off (previously known as Pythium ultimum). We hypothesised that differences in the microbial community composition of spinach seed lots correlate with the levels of damping-off suppressiveness of each seed lot. Here, we show that a large proportion of variance in seed-associated bacterial (16S) and fungal (ITS1) amplicon sequences was explained by seed lot identity, while 9.

Magnusiomyces capitatus is an environmental fungus found in soil, water, air, plants, and dairy products which may cause opportunistic infections in patients with haematological disorders resulting in high mortality rates. This series of the first reported cases in Ireland discusses investigation of two patients with underlying haematological disorders, hospitalised in the Irish National Adult Stem Cell Transplant Unit (NASCTU), who developed line-related fungaemias with M. capitatus within a three-month period.

Plant microbiomes have a major influence on forest structure and functions, as well as tree fitness and evolution. However, a comprehensive understanding of variations in fungi along the soil-plant continuum, particularly within tree seedlings, under global warming is lacking. Here, we investigated the dynamics of fungal communities across different compartments (including bulk soil and rhizosphere soil) and plant organs (including the endosphere of roots, stems and leaves) of Schima superba seedlings exposed to experimental warming and drought using AccuITS absolute quantitative sequencing.

Extracellular hydrolytic activity (phospholipase, protease and hemolysin production) was evaluated in 178 strains of potentially pathogenic ascomycetous (Candida parapsilosis, Candida tropicalis) and basidiomycetous (Rhodotorula mucilaginosa) yeasts isolated from the excreta of Mew Gulls. Two bird colonies, one nesting in a natural habitat and the other in an urban habitat at the landfill, were studied simultaneously during their 7-month breeding season. Significant differences in phospholipase and protease production were found between natural and anthropophized strains.
