“…3). Our findings suggest that the inability to produce ballistoconidia reported by Fell et al (2002) for two strains may be due to loss of the characteristic because of prolonged maintenance in the laboratory. Negative results were obtained in crossings involving the novel isolates and also strains PYCC 5678 T (=CBS 7500 T ) and PYCC 5679 (=CBS 7501) of Sporobolomyces ruberrimus.…”

During a survey of carotenogenic yeasts carried out in north-western Patagonia (Argentina), several ballistoconidia-producing strains belonging to the order Sporidiobolales were isolated from aquatic environments. Five strains were found to represent two novel species, for which the names Sporidiobolus longiusculus and Sporobolomyces patagonicus are proposed, with CBS 9654T (=PYCC 5818T=CRUB 1044T) and CBS 9657T (=PYCC 5817T=CRUB 1038T) as the type strains, respectively. The elongated basidia, which are five to six times longer that those of the remaining species of the genus Sporidiobolus, are a particular micromorphological feature of Sporidiobolus longiusculus. On the basis of the sequences of the D1/D2 domains of the 26S rRNA gene, the species most closely related to Sporidiobolus longiusculus is Sporobolomyces bannaensis, whereas Sporobolomyces marcillae is the closest relative of Sporobolomyces patagonicus. Complete internal transcribed spacer sequence analysis confirmed the separate position of Sporidiobolus longiusculus, whereas for Sporobolomyces patagonicus no nucleotide differences were found with respect to Sporidiobolus pararoseus CBS 491T. Negative mating experiments between strains of Sporobolomyces patagonicus and strains of Sporidiobolus pararoseus together with the low DNA–DNA reassociation values for the type strains of the two species validated the proposal of Sporobolomyces patagonicus as a distinct species. Information on additional Patagonian Sporobolomyces isolates is also included in this report.

The malting ecosystem consists of two components: the germinating cereal grains and the complex microbial community. Yeasts and yeast-like fungi are an important part of this ecosystem, but the composition and the effects of this microbial group have been largely unknown. In this study we surveyed the development of yeasts and yeast-like fungi in four industrial scale malting processes. A total of 136 malting process samples were collected and examined for the presence of yeasts growing at 15, 25 and 37 degrees C. More than 700 colonies were isolated and characterized. The isolates were discriminated by PCR-fingerprinting with microsatellite primer (M13). Yeasts representing different fingerprint types were identified by sequence analysis of the D1/D2 domain of the 26S rRNA gene. Furthermore, identified yeasts were screened for the production of alpha-amylase, beta-glucanase, cellulase and xylanase. A numerous and diverse yeast community consisting of both ascomycetous (25) and basidiomycetous (18) species was detected in the various stages of the malting process. The most frequently isolated ascomycetous yeasts belonged to the genera Candida, Clavispora, Galactomyces, Hanseniaspora, Issatchenkia, Pichia, Saccharomyces and Williopsis and the basidiomycetous yeasts to Bulleromyces, Filobasidium, Cryptococcus, Rhodotorula, Sporobolomyces and Trichosporon. In addition, two ascomycetous yeast-like fungi (black yeasts) belonging to the genera Aureobasidium and Exophiala were commonly detected. Yeasts and yeast-like fungi produced extracellular hydrolytic enzymes with a potentially positive contribution to the malt enzyme spectrum. Knowledge of the microbial diversity provides a basis for microflora management and understanding of the role of microbes in the cereal germination process.

“…The ability of Sporobolomyces to eject conidia into the air tends to explain why some strains have been isolated from the atmosphere, for example, S. roseus (Fell et al. ). Interestingly, the harsh conditions that can be encountered on plant leaves may also be experienced in clouds.…”

By taking advantage of the ballistoconidium‐forming capabilities of members of the genus Sporobolomyces, we recovered ten isolates from deciduous tree leaves collected from Vermont and Washington, USA. Analysis of the small subunit ribosomal RNA gene and the D1/D2 domain of the large subunit ribosomal RNA gene indicate that all isolates are closely related. Further analysis of their physiological attributes shows that all were similarly pigmented yeasts capable of growth under aerobic and microaerophilic conditions, all were tolerant of repeated freezing and thawing, minimally tolerant to elevated temperature and desiccation, and capable of growth in liquid or on solid media containing pectin or galacturonic acid. The scientific literature on ballistoconidium‐forming yeasts indicates that they are a polyphyletic group. Isolates of Sporobolomyces from two geographically separated sites show almost identical phenotypic and physiological characteristics and a monophyly with a broad group of differently named Sporobolomyces/Sporidiobolus species based on both small subunit ribosomal RNA (SSU rRNA) and D1/D2 domains of the LSU rRNA gene sequences.
