Cím:	New Strain of Cyphellophora olivacea Exhibits Striking Tolerance to Sodium Bicarbonate / Lajos Acs-Szabo, Laszlo Attila Papp, Hajnalka Csoma, Ida Miklos, Matthias Sipiczki
Dátum:	2022
ISSN:	1424-2818
Megjegyzések:	The cyanobacterium strain Synechococcus cedrorum SAG 88.79 stock culture has fungal contamination stated by the Sammlung von Algenkulturen der Universität Göttingen itself. In this recent work, this particular fungal strain was isolated, identified, and morphologically characterised. The fungal strain AGSC12 belongs to the species Cyphellophora olivacea, with respect to the sequence similarity, phylogeny, and morphology of the strain. Colony morphology and growth capability were examined on SMA, EMMA, PDA, MEA, YEA, and YPA plates. Growth of the colonies was the most successful on YPA plates, followed by PDA and MEA containing plates. Surprisingly, the AGSC12 strain showed extreme tolerance to NaHCO3 , albeit it, is is considered a general fungistatic compound. Moreover, positive association between the AGSC12 and SAG 88.79 strains was revealed, as the SAG 88.79 strain always attained higher cell density in co-cultures with the fungus than in mono-cultures. Besides, a taxonomic note on the SAG 88.79 strain itself was also stated.

Cím:	Insight into the Yeast Diversity of Hungarian Honeys / Mónika Molnár, Lajos Ács-Szabó, László Attila Papp, Zoltán Cziáky, Ida Miklós
Dátum:	2025
ISSN:	1424-2818
Megjegyzések:	To learn about the yeast biodiversity of Hungarian honeys and to isolate osmotolerant yeasts, fifteen different honey varieties, beeswax, and bee bread were purchased, and samples of another, but highly osmotic material, tree sap (cherry, sour cherry, and plum), were collected from the northeastern region of the country. In total, 60 yeast strains were isolated and their taxonomic positions were determined by barcode sequences using ITS1-NL4 primers. The honey products contained mostly Zygosaccharomyces and Starmerella species. In addition, Hanseniaspora uvarum, Rhodotorula mucilaginosa and diobovata, Sporobolomyces roseus, Filobasidium magnum, Naganishia sp., and Aureobasidium pullulans were also present in smaller numbers. In contrast, tree saps contained Metschnikowia and Pichia fermentas cells. Further results suggest that some of the yeasts in honey can only "survive", while others can propagate at high sugar levels, generally between 600 and 700 mg/g, with a predominance of fructose. Properties important for pathogenicity, such as invasive hyphae production, gelatin melting ability, and growth at 37 ?C, were also examined. Hanseniaspora uvarum and Pichia fermentans representatives seemed to be negative for gelatin hydrolysis, while the other strains were able to melt gelatin. Although some of the strains could produce hyphae-like structures at 25 ?C, none of them could grow at 37 ?C.
