Yeasts producing zeatin

Identification of polysaccharide-producing black yeasts.

Isolation, identification and screening of hidrolytic enzymes producing phylloplane yeasts

Background Microorganisms are common colonizers of superficial (phylloplane) and internal tissues (endophyte) of a variety plant species [1]. Phylloplane yeasts are considered a promising source of new and interesting biotechnological activities, particularly hydrolytic enzymes; however, the diversity of yeasts colonizing plant phylloplane and is still poorly known for most plant species. Consi...

Comparative Activity of Isomers of Zeatin and Ribosyl-Zeatin on Funaria hygrometrica.

The activities of isomers of zeatin, ribosyl-zeatin, and 6-(gamma,gamma-dimethylallylamino) purine (i(6)Ade) on the moss Funaria hygrometrica are compared by measuring the ability of the cytokinins to induce callus or gametophores. The cis- and trans-ribosyl-zeatins were inactive, and therefore this kind of bioassay cannot be used as evidence for the presence or absence of a cytokinin in tests ...

Indole-3-Acetic Acid-Producing Yeasts in the Phyllosphere of the Carnivorous Plant Drosera indica L

Yeasts are widely distributed in nature and exist in association with other microorganisms as normal inhabitants of soil, vegetation, and aqueous environments. In this study, 12 yeast strains were enriched and isolated from leaf samples of the carnivorous plant Drosera indica L., which is currently threatened because of restricted habitats and use in herbal industries. According to similarities...

Isolation, biochemical and genetic characterizations of alcohol-producing yeasts from the flowers of Woodfordia fruticosa.

OBJECTIVE To isolate and characterize the alcohol-producing yeasts from Woodfordia fruticosa flowers, which are used for the induction and maintenance of fermentation in the making of Ayurvedic formulations. MATERIALS AND METHODS Initially twenty four yeasts strains were isolated on MGYP agar plate. Among them, four strains were selected for further studies on the basis of their alcohol gener...
