Microflora in wound sites of preharvest maize (including bacteria, yeasts, and filamentous fungi) may play a role in attracting insects to maize plants and may also interact with growth and mycotoxin production by filamentous fungi. As little data are available about the yeasts occurring on maize from the U.S. corn belt, samples of milled maize from experimental plantings at the University of Illinois River Valley Sand Field were analyzed. Yeast counts showed slight yearly fluctuation and varied between 3.60 and 5.88 (log cfu/g maize). The majority of the yeasts were Candida guilliermondii (approximately 55%), Candida zeylanoides (24 %), Candida shehatae (11%), and Debaryomyces hansenii (3%). Also present were Trichosporon cutaneum, Cryptococcus albidus var. aerius, and Pichia membranifaciens. The occurrence of killer yeasts was also evaluated. Killer yeasts were detected in maize for the first time and were identified as Trichosporon cutaneum and Candida zeylanoides. These were able to kill some representative yeasts isolated from maize, including Candida guilliermondii, Candida shehatae, and Cryptococcus albidus var. aerius. Other maize yeasts (Candida zeylanoides, Debaryomyces hansenii, Pichia membranifaciens) were not affected. The majority of yeasts found on maize were unable to ferment its major sugars, i.e., sucrose and maltose. Some (e.g., Candida zeylanoides) were not even able to assimilate these sugars. The importance of these properties in relation to insect attraction to preharvest ears of maize is discussed.Key words: corn, maize, yeast, killer.

ABSTRACT Yeast isolates from raw and processed poultry products were characterized using PCR amplification of the internally transcribed spacer (ITS) 5.8S ribosomal DNA region (ITS-PCR), restriction analysis of amplified products, randomly amplified polymorphic DNA (RAPD) analysis, and pulsed-field gel electrophoresis (PFGE). ITS-PCR resulted in single fragments of 350 and 650 bp, respectively, from eight strains of Yarrowia lipolytica and seven strains of Candida zeylanoides. Digestion of amplicons with HinfI andHaeIII produced two fragments of 200 and 150 bp fromY. lipolytica and three fragments of 350, 150, and 100 bp from C. zeylanoides, respectively. Although these fragments showed species-specific patterns and confirmed species identification, characterization did not enable intraspecies typing. Contour-clamped heterogeneous electric field PFGE separated chromosomal DNA of Y. lipolytica into three to five bands, most larger than 2 Mbp, whereas six to eight bands in the range of 750 to 2,200 bp were obtained from C. zeylanoides. Karyotypes of both yeasts showed different polymorphic patterns among strains. RAPD analysis, using enterobacterial repetitive intergenic sequences as primers, discriminated between strains within the same species. Cluster analysis of patterns formed groups that correlated with the source of isolation. For ITS-PCR, extraction of DNA by boiling yeast cells was successfully used.

Candida Zeylanoides

This study evaluates the efficacy of yeasts isolated from soil in the treatment of textile wastewater. Two yeast species were isolated from soil; they were identified as Candida zeylanoides and Saccharomyces cerevisiae. The yeasts were inoculated into flask containing effluent and incubated for 15 days. Saccharomyces cerevisiae showed the most significant treatment capacity with a 66% reduction in BOD; this was followed closely by Candida zeylanoides with 57.3% reduction in BOD and a consortium of the two species showed the least remediation potential of 36.9%. The use of Saccharomyces cerevisiae and Candida zeylanoides in treatment of textile wastewater will help to limit the adverse environmental and health implications associated with disposal of untreated effluent into water bodies.

O isolamento de micro-organismos de ambientes onde se conhece pouco da biodiversidade microbiana, como o semi-árido nordestino, tem incentivado, nas últimas décadas, um aumento nos estudos de bioprospecção microbiana. Desta forma, pesquisas envolvendo o potencial biotecnológico desses organismos vem proporcionando a descoberta de novos produtores de compostos bioativos de alto valor agregado (LIU et al., 2012; SMRITHI et al., 2013; MONCIARDINI et al., 2014).Atualmente, a pesquisa de compostos bioativos naturais com aplicação no tratamento e prevenção de doenças humanas tem vindo a ganhar cada vez mais importância (DONADIO et al., 2010).Os fungos são conhecidos por seu papel ambiental, por sua versatilidade na obtenção de metabólitos secundários e pela facilidade na reprodutibilidade de resultados, porém, apesar dos fungos serem reconhecidos como uma importante fonte de produtos bioativos naturais é estimada que, uma grande quantidade destes compostos, se encontre ainda por identificar (SANTOS, 2012; HIGGINBOTHAM, 2013).
