Candida flosculorum sp. nov. and Candida floris sp. nov., two yeast species associated with tropical flowers

Abstract

Two ascomycetous yeast species, Candida flosculorum sp. nov. and Candida floris sp. nov., were isolated from tropical flowers and their associated insects. C. flosculorum was isolated from flower bracts of Heliconia velloziana and Heliconia episcopalis (Heliconiaceae) collected from two Atlantic rain forest sites in Brazil. C. floris was isolated from flowers of Ipomoea sp. (Convolvulaceae) growing on the banks of the river Paraguai in the pantanal ecosystem in Brazil and from an adult of the stingless bee Trigona sp. and a flower of Merremia quinquefolia (Convolvulaceae) in Costa Rica. C. flosculorum belongs to the Metschnikowiaceae clade and C. floris belongs to the Starmerella clade. The type strain of C. flosculorum is UFMG-JL13T (=CBS 10566T=NRRL Y-48258T) and the type strain of C. floris is UWO(PS) 00-226.2T (=CBS 10593T=NRRL Y-48255T).

Four novel species of the anamorphic yeast genus Candida found in Thailand and Taiwan

“…It is well-known that many novel species isolated from insect-associated substrates belong to the Clavispora-Metschnikowia clade (Lachance et al, 1999;Nguyen et al, 2007;Rosa et al, 2007). As mentioned above, among the species in the C. bambusicola subclade , Candida bambusicola and C. nonkhaiensis were isolated from insect frass, C. succicola was isolated from exudates of a tree, and C. touchengensis was isolated from soil.…”

Starmerella caucasica sp. nov., a novel anamorphic yeast species isolated from flowers in the Caucasus

“…Lachance et al, 2001a;Nakase et al, 2010;Rosa et al, 2003Rosa et al, , 2007, their strains also occur in wine-related environments and substrates with high sugar concentration. For example, S. bombicola is quite common in fermenting grape must (Csoma and Sipiczki, 2008;Sipiczki et al, 2005) where its presence can favorably affect wine quality (Milanovic et al, 2012).…”

Candida potacharoeniae sp. nov. and Candida spenceri sp. nov., two novel galactose-containing ascomycetous anamorphic yeast species isolated in Thailand

“…The 15 strains are located in the Starmerella clade (Rosa and Lachance, 1998;Rosa et al, 2007;Teixeira et al, 2003) in a phylogenetic tree based on the D1/D2 domain sequences of the large subunit (LSU) rRNA genes but a little bit distant from known Starmerella species and located in a subclade including Candida gropengiesseri, Candida tilneyi, Candida magnoliae, Candida sorbosivorans, Candida geochares, Candida apis and Candida vaccinii (Fig. 1).…”
