Cryptococcus laurentii is one of the non-neoformans cryptococci that have rarely been isolated from humans. We report a case of repeated colonization of the oropharynx by Cr. laurentii in a patient with erythroleukaemia. The isolate was identified by phenotypic and genotypic tests and showed resistance to fluconazole.

Unlabelled: Bioprospecting can uncover new yeast strains and species with interesting ecological characteristics and valuable biotechnological traits, such as the capacity to convert different carbon sources from industrial side and waste streams into bioproducts. In this study, we conducted untargeted yeast bioprospecting in tropical West Africa, collecting 1,996 isolates and determining their growth in 70 different environments. While the collection contains numerous isolates with the potential to assimilate several cost-effective and sustainable carbon and nitrogen sources, we focused on characterizing the 203 strains capable of growing on lactose, the main carbon source in the abundant side stream cheese whey from dairy industries.

Breast milk contains a diverse array of symbiotic microorganisms, including beneficial probiotics. While most research has focused on the bacterial composition of breast milk, the fungal community (mycobiota) has received limited attention. In this study, we isolated and evaluated yeast strains from breast milk, demonstrating the safety and probiotic potential of four strains through hemolysis tests, antimicrobial activity, tolerance to gastrointestinal conditions, aggregation, cell adhesion, and antioxidant activity assays.

Article Synopsis
  • Green mould disease is a serious problem for the citrus industry, with Cryptococcus laurentii showing potential to boost fruit defense systems.
  • A study focused on the effects of C. laurentii cultured with carboxymethyl cellulose (CMCC. laurentii) on grapefruit, revealing that this treatment helps reduce disease symptoms and increases beneficial metabolic processes.
  • By enhancing gene expression related to yeast growth and activating crucial metabolic pathways, CMCC. laurentii improved phenylpropane and reactive oxygen metabolism, which ultimately helps maintain the quality of postharvest grapefruit.

, an ancient plant species endemic to Yunnan Province, China, remains underexplored in terms of its endophytic bacterial communities. The plant tissue pedicel serves as the connection between the flower and the stem, not only delivers nutrients but also transmits metabolic substances from endophytic bacteria to the nectar during long-term microbial colonization and probably improves the antagonistic activity of nectar against yeast. Hence, 138 isolates of endophytic bacteria have been isolated in this study from the pedicels of 12- and 60-year-old .
