“…In this study, Penicillium was detected in 15 of the total 27 samples of eight kinds of fruits. The reason for this high frequency was considered the same as that for Cladosporium; both genera are ubiquitous in the environment (8,14,20,33). The well-known blue rot occurs in various fruits (22,27), and the pathogen can rapidly contaminate many individual fruits during cultivation, harvesting, handling, transport, storage, and marketing because the rot spreads by contact.…”

A comprehensive and quantitative analysis of the mycoflora on the surface of commercial fruit was performed. Nine kinds of fruits grown in Japan were tested. Overall fungal counts on the fruits ranged from 3.1 to 6.5 log CFU/g. The mean percentages of the total yeast counts were higher than those of molds in samples of apples, Japanese pears, and strawberries, ranging from 58.5 to 67.0%, and were lower than those of molds in samples of the other six fruits, ranging from 9.8 to 48.3%. Cladosporium was the most frequent fungus and was found in samples of all nine types of fruits, followed by Penicillium found in eight types of fruits. The fungi with the highest total counts in samples of the various fruits were Acremonium in cantaloupe melons (47.6% of the total fungal count), Aspergillus in grapes (32.2%), Aureobasidium in apples (21.3%), blueberries (63.6%), and peaches (33.6%), Cladosporium in strawberries (38.4%), Cryptococcus in Japanese pears (37.6%), Penicillium in mandarins (22.3%), and Sporobolomyces in lemons (26.9%). These results demonstrated that the mycoflora on the surfaces of these fruits mainly consists of common pre- and postharvest inhabitants of the plants or in the environment; fungi that produce mycotoxins or cause market diseases were not prominent in the mycoflora of healthy fruits. These findings suggest fruits should be handled carefully with consideration given to fungal contaminants, including nonpathogenic fungi, to control the quality of fruits and processed fruit products.

“…The species A. pullulans and C. laurentii have been often associated with the surface of plants. They were isolated from all leaves regardless of plant or location (Andrews et al, 2002;Inácio et al, 2002;Pereira et al, 2002). Cryptococcus laurentii has been reported to be heterogenous based on DNA G + C content, whole-cell protein electrophoretic patterns, and the sequences of the D 1 /D 2 region of 26S rDNA and ITS regions (Sugita et al, 2000;Takashima et al, 2003).…”

Yeasts were isolated from leaf surfaces of five species of fruit trees located in southwest Slovakia. One hundred and fifty five yeast strains belonging to 11 genera were isolated from 300 samples of leaves. Seventeen yeast species were identified, but only three occurred regularly: Aureobasidium pullulans, Cryptococcus laurentii, and Metschnikowia pulcherrima. Species such as Hanseniaspora uvarum, Pichia anomala, Rhodotorula glutinis, and Saccharomyces cerevisiae, were isolated less frequently. We found only few differences in the yeast community isolated from leaves of different tree species although dominant species occurred regularly on the majority of leaves. Furthermore, yeast species varied throughout years. In spite of the fact that the yeast community occupying the leaves of the fruit trees was studied in the samples harvested in three localities, which are distanced from each other some kilometers, the qualitative representation of the most isolated yeasts was identical. The differences were only in the frequency of the incidence of individual species in the samples.

“…In consequence, only few papers have been published regarding fungal (Inacio et al 2002;Pereira et al 2002) or bacterial communities (Yadav et al 2004a;Karamanoli et al 2000;Caponero et al 1995;PØrissol et al 1993;Ercolani 1991). The Mediterranean environment, typified by the alternation of a cold and relatively wet period with a hot and dry one, is unique in that factors favouring growth (appropriate temperature regimes and water availability) do not coincide for a considerable part of the year.…”

Abundance and diversity of the phyllosphere bacterial communities of Mediterranean perennial plants that differ in leaf chemistry

et al. 2008

We studied the epiphytic bacterial communities of the summer leaves of eight perennial species naturally occurring in a Mediterranean ecosystem. The species differ in essential-oil content (from rich in essential oil to non-producers) and composition, and also in life form (from herbaceous species to tall shrubs). We compared the epiphytic bacterial communities on the basis of (i) their abundance, (ii) their metabolic profile (derived by use of the BIOLOG Ecoplate system) and (iii) richness and diversity of substrates that they use, as a measure of functional diversity. Among all species, the aromatic Melissa officinalis was the most abundantly colonized. The bacterial communities on the leaves of the aromatic Myrtus communis, Calamintha nepeta and Melissa officinalis, and also of Cistus incanus catabolized all 31 substrates offered; those on the evergreen-sclerophyllous species, Arbutus unedo and Quercus coccifera, catabolized only 14 and 17 substrates, respectively. Carbohydrates were consistently used abundantly by all communities, whereas carboxylic acids were most variably used. On average, the group of aromatic plants scored higher regarding bacterial abundance, and richness and diversity of substrates used by the bacterial communities on their leaves; the lowest values for both substrate-use indices were recorded in A. unedo. Bacterial abundance or richness or diversity of substrates used did not vary with leaf oil content. Abundance was positively correlated with both substrate-use indices. Results support claims that the antimicrobial effects of essential oils are not exerted so much under natural conditions as reports based on biassays with pathogens usually show. Although essential oils play a part in the microbial colonization of the phyllosphere, it is not likely that inhibition of phyllosphere bacteria is essential oils primary role, at least in the Mediterranean environment.
