ABSTRACTA rich history of investigation documents variousDrosophila-yeast mutualisms, suggesting thatDrosophila suzukiisimilarly has an association with a specific yeast species or community. To discover candidate yeast species, yeasts were isolated from larval frass, adult midguts, and fruit hosts ofD. suzukii. Terminal restriction fragment length polymorphism (TRFLP) technology and decimal dilution plating were used to identify and determine the relative abundance of yeast species present in fruit juice samples that were either infested withD. suzukiior not infested. Yeasts were less abundant in uninfested than infested samples. A total of 126 independent yeast isolates were cultivated from frass, midguts, and fruit hosts ofD. suzukii, representing 28 species of yeasts, withHanseniaspora uvarumpredominating. This suggests an association betweenD. suzukiiandH. uvarumthat could be utilized for pest management of the highly pestiferousD. suzukii.

“…SEM studies demonstrated that A. pullulans colonized pPVC in the absence of other microorganisms and therefore acts as a primary colonizer of pPVC. A. pullulans is increasingly recognized as the major causative agent of defacement of various diverse materials, such as painted surfaces (11,21,48) and wood (27), in addition to pPVC exposed to tropical conditions (24,40). The present study demonstrates that A. pullulans is also an important colonizer of pPVC in temperate climates.…”

Significant substratum damage can occur when plasticized PVC (pPVC) is colonized by microorganisms. We investigated microbial colonization of pPVC in an in situ, longitudinal study. Pieces of pPVC containing the plasticizers dioctyl phthalate and dioctyl adipate (DOA) were exposed to the atmosphere for up to 2 years. Fungal and bacterial populations were quantified, and colonizing fungi were identified by rRNA gene sequencing and morphological characteristics. Aureobasidium pullulans was the principal colonizing fungus, establishing itself on the pPVC between 25 and 40 weeks of exposure. A group of yeasts and yeast-like fungi, including Rhodotorula aurantiaca and Kluyveromyces spp., established themselves on the pPVC much later (after 80 weeks of exposure). Numerically, these organisms dominated A. pullulans after 95 weeks, with a mean viable count ؎ standard error of 1,000 ؎ 200 yeast CFU cm ؊2 , compared to 390 ؎ 50 A. pullulans CFU cm ؊2 . No bacterial colonization was observed. We also used in vitro tests to characterize the deteriogenic properties of fungi isolated from the pPVC. All strains of A. pullulans tested could grow with the intact pPVC formulation as the sole source of carbon, degrade the plasticizer DOA, produce extracellular esterase, and cause weight loss of the substratum during growth in vitro. In contrast, several yeast isolates could not grow on pPVC or degrade DOA. These results suggest that microbial succession may occur during the colonization of pPVC and that A. pullulans is critical to the establishment of a microbial community on pPVC.Plasticized PVC (pPVC) is highly susceptible to microbial attack in many different environmental situations. The problem was first identified in U.S. government reports of the deterioration of military equipment (8, 44), and subsequent reports described defacement and deterioration of commercial pPVC products (20,50). Biodeterioration of pPVC is now known to occur in a wide range of industrial, commercial, and structural applications (18,19,22).The susceptibility of pPVC results from the presence of plasticizers, commonly organic acid esters such as dioctyl phthalate (DOP) and dioctyl adipate (DOA), added to modify physical or mechanical properties of the polymer. Both bacteria (6,7,14) and fungi (5, 36) can degrade ester-based plasticizers. Loss of plasticizers from pPVC due to microbial degradation results in brittleness, shrinkage, and ultimately failure of the pPVC in its intended application.Microbial deterioration of pPVC has been studied extensively in vitro. Many studies have examined the resistance of pPVC formulations incorporating biocides to colonization by test organisms (38,39,46). Other research has determined biodegradability by measuring changes in the physical properties of pPVC, such as changes in tensile strength (49), mass (9), or electrical properties (42) during biodegradation. Several international standard test methods for microbiological susceptibility of plastics have been established (1, 2, 26).Colonization processes occurring...

Summary — One-hundred and forty-eight molds were isolated from the following samples of almond, Prunus dulcis, pollen : floral pollen collected by hand; corbicular pollen from pollen traps placed on colonies of honey bees, Apis mellifera, in the almond orchard; and bee bread stored in comb cells for one, three, and six weeks. The majority of molds identified were Penicillia (32%), Mucorales (21%), and Aspergilli (17%). In general, the number of isolates decreased in pollen as it was collected and stored by the bees. Each type of pollen sample appeared to differ in regard to mold flora and dominant species. Aureobasidium
