As compared to organic farming system, conventional farming system relies on higher inputs of synthetic agrochemicals, which may reduce the abundance, diversity, and beneficial effects of plant endophytic fungal communities. This study compares the diversity and abundance of culturable endophytic fungal communities associated with four plant species –corn, tomato, pepper, and watermelon grown in separate organic and conventional fields. In all, 740 fungal isolates were identified, of which 550 were from the organic fields and 190 from the conventional ones. These fungal isolates were grouped into eight orders and 22 species, with the two most abundant species being Trichoderma sp. and Pichia guilliermondi. The fungal species diversity and abundance were both significantly higher in the organic than in the conventional fields. All the isolated endophytic fungi improved tomato plants’ shoot growth and biomass significantly, as compared with the water control. Six fungal isolates also exhibited activity that enhanced tomato fruit yields. These results suggest that these endophytic fungi might be a considerable boost to sustainable agricultural production, while also reducing the agricultural application of chemicals and thus benefiting the environment and human health.

“…Additionally, some members of the Hanseniaspora genus have shown potential as biocontrol agents. H. uvarum has provided effective control of chilli fruit rot (Basha and Ramanujam, 2015), Botrytis cinerea mould in grapes (Liu et al, 2010;Romanazzi et al, 2012), Penicillium digitatum and Penicillium italicum decay in citrus Taqarort et al, 2008), post-harvest decay of strawberries (Cai et al, 2015) and post-harvest decay of grape, peach and apple fruits (McLaughlin et al, 1992).…”

Yeasts found in vineyards and wineries

Wine is a complex beverage, comprising thousands of metabolites that are produced through the action of a plethora of yeasts and bacteria during fermentation of grape must. These microbial communities originate in the vineyard and the winery and reflect the influence of several factors including grape variety, geographical location, climate, vineyard spraying, technological practices, processing stage and season (pre-harvest, harvest, post-harvest). Vineyard and winery microbial communities have the potential to participate during fermentation and influence wine flavour and aroma. Therefore, there is an enormous interest in isolating and characterising these communities, particularly non-Saccharomyces yeast species to increase wine flavour diversity, while also exploting regional signature microbial populations to enhance regionality. In this review we describe the role and relevance of the main non-Saccharomyces yeast species found in vineyards and wineries. This includes the latest reports covering the application of these species for winemaking; and the biotechnological characteristics and potential applications of non-Saccharomyces species in other areas. In particular, we focus attention on the species for which molecular and genomic tools and resources are available for study. Copyright © 2016 John Wiley & Sons, Ltd.

“…The species is thus extensively assessed as a biocontrol agent against Botrytis cinerea (gray mold) on grapes and strawberries (Long et al, 2005 ; Liu et al, 2010a , b ; Cai et al, 2015 ), Penicilium spp. (fruit rot) on citrus (Long et al, 2005 ), Colletotrichum capsici (fruit rot) on chili (Basha and Ramanujam, 2014 ), etc., while the underlying mechanisms of action are actively studied (Liu et al, 2014 ; Pu et al, 2014 ). The ecological extent of H. uvarum is large: it has been collected from soils (Capriotti, 1955 ), plants (Sláviková et al, 2009 ), insects (Nguyen et al, 2007 ), birds (Kocan and Hasenclever, 1972 ), molluscs (de Araujo et al, 1995 ), and shrimps (Pagnocca et al, 1989 ), while its occurrence as clinical isolate on humans is rare and considered as opportunistic (Emmanouil-Nikoloussi et al, 1994 ; Garcia-Martos et al, 1999 ).…”

Hanseniaspora uvarum from Winemaking Environments Show Spatial and Temporal Genetic Clustering

Hanseniaspora uvarum is one of the most abundant yeast species found on grapes and in grape must, at least before the onset of alcoholic fermentation (AF) which is usually performed by Saccharomyces species. The aim of this study was to characterize the genetic and phenotypic variability within the H. uvarum species. One hundred and fifteen strains isolated from winemaking environments in different geographical origins were analyzed using 11 microsatellite markers and a subset of 47 strains were analyzed by AFLP. H. uvarum isolates clustered mainly on the basis of their geographical localization as revealed by microsatellites. In addition, a strong clustering based on year of isolation was evidenced, indicating that the genetic diversity of H. uvarum isolates was related to both spatial and temporal variations. Conversely, clustering analysis based on AFLP data provided a different picture with groups showing no particular characteristics, but provided higher strain discrimination. This result indicated that AFLP approaches are inadequate to establish the genetic relationship between individuals, but allowed good strain discrimination. At the phenotypic level, several extracellular enzymatic activities of enological relevance (pectinase, chitinase, protease, β-glucosidase) were measured but showed low diversity. The impact of environmental factors of enological interest (temperature, anaerobia, and copper addition) on growth was also assessed and showed poor variation. Altogether, this work provided both new analytical tool (microsatellites) and new insights into the genetic and phenotypic diversity of H. uvarum, a yeast species that has previously been identified as a potential candidate for co-inoculation in grape must, but whose intraspecific variability had never been fully assessed.
