“…Findings presented herein show that adhesion and germination of conidia, two life-cycle events important to the survival of B. cinerea on the surface of apple fruit, were stimulated by acetate esters. This is the first report of this acetate ester effect on fungal spores on apple fruit, although the effect has been reported for conidia on polycarbonate membranes ( , ). This is also the first report of the stimulation of conidial adhesion and germination by 2MBA.…”

“…Conidial adhesion and germination always occurred on apple slices used for controls, and conidia exhibited no abnormal behavior when on apple slices. In most of the experiments conidia of isolate F-J-4 was the model organism because it is a aggressive gray mold pathogen of apples ( − ) and its conidia respond to acetate ester stimulation ( , ). Butyl acetate was routinely used because it is frequently found in higher concentrations in apple tissue, as shown by the ca.…”

Ethyl acetate, 2-methylbutyl acetate, butyl acetate (BA), and hexyl acetate were detected by solid-phase microextraction and gas-liquid chromatography inside slices of Golden Delicious apple and in water droplets on the skin of slices incubated in sealed glass jars. Conidial adhesion and germination of the gray mold fungus, Botrytis cinerea, was assessed on apple slices after exposure or no exposure to the esters in the headspaces of glass jars. Attached conidia were dislodged by sonication and remaining conidia on apple slices were counted by microscopy. Adhesion generally increased as BA increased to 7.2 microg mL(-1), but declined with greater concentrations. BA at 0-3.6 microg mL(-1) for 24 h stimulated adhesion 2-fold greater compared to that at 4 h. Adhesion stimulated by BA increased as a function of time (0-24 h), showing linear trends (r (2) = 0.99; p = 0.01) during 0-12 h. The four esters were similar in their ability to stimulate adhesion. Germination of conidia exposed to BA increased linearly (r (2) = 0.95-0.98; p = 0.01) during 4-12 h. Conidial adhesion stimulated by BA preceded conidial germination by 2 h. The four esters stimulated conidial germination to similar levels. Results indicated that acetate esters formed in apple fruit are mycoactive, influencing life-cycle events of B. cinerea important to its survival on the fruit. The similar responses of three B. cinerea isolates to four acetate esters suggests a common stimulation mechanism may operate in B. cinerea.

Effect of ester compounds on biogas production: beneficial or detrimental?

Esters are major flavor compounds in fruits, which are produced in high volume. The widespread availability of these compounds in nature attracts interest on their behavior in anaerobic digestion in waste and wastewater treatments. The aim of this work was to study the effects of various esters at different concentrations in anaerobic digestion followed by determination of their minimum inhibitory concentration (MIC), and to study the effect of chain length of functional group and alkyl chain of ester on methane production. Addition of methyl butanoate, ethyl butanoate, ethyl hexanoate, and hexyl acetate at concentration up to 5 g L À1 increased methane production, while their higher concentrations inhibited the digestion process. The MIC values for these esters were between 5 and 20 g L À1 . Except hexyl acetate, the esters at concentration 5 g L À1 could act as sole carbon source during digestion. For ethyl esters, increasing number of carbon in functional group decreased methane production. For acetate esters, alkyl chain longer than butyl inhibited methane production. Effect of ester on methane production is concentration-dependent.

Emission patterns of wound volatile compounds following injury of ripe strawberry fruit

et al. 2003

Volatile compounds emitted from plants following wounding influence the growth of fungal pathogens, including Botrytis cinerea (grey mould), which causes serious economic loss of strawberry fruit. In the present study the patterns of volatile compound emission from ripe strawberry fruit, comprising store-purchased fruit and two known cultivars, were determined following injury, using solid phase microextraction analysis to sample a stream of air continuously flowing over the fruit. The principal compounds produced from all fruits comprised C 6 aldehydes, alcohols and acetate and butyrate esters derived from the lipoxygenase-hydroperoxide lyase pathway. There was an initial burst of production of aldehydes, including t-2-hexenal, following wounding and then a gradual decline, which in one cultivar continued for 3 h. t-2-Hexenal is of special interest, since it has been shown to inhibit or promote Botrytis growth in vitro depending on concentration. The acetate esters t-2-hexenyl acetate, c-3-hexenyl acetate and hexyl acetate were major wound compounds released by the fruit and were produced for 3 h after wounding. The production of relatively large quantities of wound-derived esters is markedly different from the patterns observed for most vegetative tissue. Knowledge of the wound compounds produced by strawberry fruit and their profiles of emission after injury provides a basis for studies of the potential roles of these compounds in pathogen development on fruit.
