Patulin Fact Sheet Background Information: Patulin takes it’s name from the fungus from which it was first isolated, Penicillium patulum. It is most likely to occur in moldy fruits, such as apples, but may also be found in grains, especially wet grains, and silages. Patulin may be associated with problems in silages, however the data on that aspect has not been well established. Since Patulin is associated with storage molds, it should be considered when investigating silage problems, specifically regarding dairy catte. Can co-contaminate feedstuffs with other Penicillium toxins, such as, Ochratoxin A (OTA), Citrinin, Roquefortine C, Mycophenolic Acid (MPA), and Cyclopiazonic Acid. Major crops affected: Corn, Barley, Wheat, & Rye, their associated silages, and Fruits. Associated Mold: Penicillium sp., Aspergillus sp., and Byssochlamys sp. Conditions favoring production: Penicillium is a major silage mold and may be a greater silage problem because it can grow at lower pH than do other molds. Considered to be more prevalent from a storage mold situation, rather than field/growing condition mold situation. Symptoms: Patulin is an antibiotic against gram-positive bacteria. In ruminants, Patulin has been shown to reduce VFA production, fiber digestion, and bacterial yield. Also, nephrotoxic (kidney) and immunotoxic effects. Gastrointestinal symptoms like gastric ulcers, intestinal hemorrages, lesions in the duodenum, and alteration of intestinal barrier function.

Incorporating Fermentation Into Undergraduate Laboratory Courses
Athens Journal of Sciences- Volume 2, Issue 4 – Pages 257-264 Incorporating Fermentation into Undergraduate Laboratory Courses By Claire Gober Madeleine Joullie† Laboratory courses in universities have a responsibility to introduce current research practices and trends in scientific research to adequately prepare students for work in the field. One such research practice gaining popularity in recent years is that of green chemistry. Since the 1960s, increasing concern over the release of toxic chemicals into the environment has led to a push for more environmentally responsible chemistry. A growing faction of chemists has begun to adopt methods to eliminate chemical waste and support green chemistry. Fermentation is an ideal technique to demonstrate environmentally sustainable chemistry in an undergraduate laboratory class. Fermentation of complex natural products, as opposed to traditional organic synthesis, is beneficial as it supports a number of principles of green chemistry; it is conducted at ambient temperature and pressure, uses inexpensive and innocuous materials, makes use of renewable resources, and does not require a fume hood. Skills implemented during fermentation can be easily taught to upper-level Chemistry and Biochemistry undergraduate students, who typically have limited exposure to complex natural products in their coursework. Such a course would be interdisciplinary in nature, incorporating fungal biology and metabolism as well as organic chemistry. Students would learn a variety of skills, including growth media selection and preparation, inoculation of fungal cultures, extraction of natural products, and purification and characterization of metabolites. Experiments of this nature would allow for discussions of several areas of research: green chemistry, natural products and their application to medicine, identification of functional groups in complex molecules by spectroscopy, and introduction to biochemistry and metabolism.

Within the large class of the epipolythiodioxopiperazines, which are typical of fungi, thiosilvatins represent a homogeneous family that, so far, has been reported in low frequency in both marine and terrestrial contexts. However, recent observations indicate that these compounds have been possibly neglected in the metabolomic characterization of fungi, particularly from marine sources. Aspects concerning occurrence, bioactivities, structural, and biosynthetic properties of thiosilvatins are reviewed in this paper. Keywords: thiosilvatins; secondary metabolites; diketopiperazines; epipolythiodioxopiperazines; fungi; biological activities 1. Introduction A huge chapter on research on biodiversity is represented by studies concerning the biochemical properties of the manifold organisms which are part of natural ecosystems. Novel secondary metabolites are continuously discovered, disclosing a surprising chemodiversity in terms of both structural and biosynthetic aspects.

Carlow, Ireland; and School of Biology and Environmental Science, College of Life Sciences, University College Dublin, Belfield, Dublin 4, Ireland Secondary metabolites produced by Penicillium paneum and Penicillium roqueforti from baled grass silage were analyzed. A total of 157 isolates were investigated, comprising 78 P. paneum and 79 P. roqueforti isolates randomly selected from more than 900 colonies cultured from bales. The findings mostly agreed with the literature, although some metabolites were not consistently produced by either fungus. Roquefortine C, marcfortine A, and andrastin A were consistently produced, whereas PR toxin and patulin were not. Five silage samples were screened for fungal metabolites, with two visually moldy samples containing up to 20 mg/kg of roquefortine C, mycophenolic acid, and andrastin A along with minor quantities (0.1-5 mg/kg) of roquefortines A, B, and D, festuclavine, marcfortine A, and agroclavine. Three visually nonmoldy samples contained low amounts of mycophenolic acid and andrastin A.

This is the first report of suspected moldy walnut toxicosis in man. An adult male ingested approximately 8 fungal-infected walnut kernels and after 12 hours experienced tremors, generalized pain, incoordination, confusion, anxiety and diaphoresis. Following symptomatic and supportive treatment at a local hospital the man made an uneventful recovery. A batch of walnuts (approximately 20) were submitted for mycological culturing and identification as well as for mycotoxin analysis. Penicillium crustosum Thom was the most abundant fungus present on walnut samples, often occurring as monocultures on isolation plates. Identifications were confirmed with DNA sequences. The kernels and shells of the moldy walnuts as well as P. crustosum isolates plated on Yeast Extract Sucrose (YES) and Czapek Yeast Autolysate (CYA) agars and incubated in the dark at 25 ºC for 7 days were screened for tremorgenic mycotoxins and known P.

Ram1,2* Abstract Background: The flamentous fungi Paecilomyces variotii and Penicillium roqueforti are prevalent food spoilers and are of interest as potential future cell factories. A functional CRISPR/Cas9 genome editing system would be benefcial for biotechnological advances as well as future (genetic) research in P. variotii and P. roqueforti. Results: Here we describe the successful implementation of an efcient AMA1-based CRISPR/Cas9 genome edit- ing system developed for Aspergillus niger in P. variotii and P. roqueforti in order to create melanin defcient strains. Additionally, kusA− mutant strains with a disrupted non-homologous end-joining repair mechanism were created to further optimize and facilitate efcient genome editing in these species. The efect of melanin on the resistance of conidia against the food preservation stressors heat and UV-C radiation was assessed by comparing wild-type and melanin defcient mutant conidia. Conclusions: Our fndings show the successful use of CRISPR/Cas9 genome editing and its high efciency in P. vari- otii and P. roqueforti in both wild-type strains as well as kusA− mutant background strains. Additionally, we observed that melanin defcient conidia of three food spoiling fungi were not altered in their heat resistance.

The brlA gene encodes a C2H2-type zinc-ﬁnger transcription factor, which is essential for asexual development. Penicillium expansum causes blue mold disease and is the main source of patulin, a mycotoxin that contaminates apple-based food. A P. expansum PeDbrlA deﬁcient strain was generated by homologous recombination. In vivo, suppression of brlA completely blocked the development of conidiophores that takes place after the formation of coremia/synnemata, a required step for the perforation of the apple epicarp. Metabolome analysis displayed that patulin production was enhanced by brlA suppression, explaining a higher in vivo aggressiveness compared to the wild type (WT) strain. No patulin was detected in the synnemata, suggesting that patulin biosynthesis stopped when the fungus exited the apple. In vitro transcriptome analysis of PeDbrlA unveiled an up-regulated biosynthetic gene cluster (PEXP_073960-PEXP_074060) that shares high similarity with the chaetoglobosin gene cluster of Chaetomium globosum.

The aim of this work was to: (i) study fungal ecology on cheese in terms of T requirements, focusing on the partitioning of mycotoxins between the rind and mycelium; and (ii) validate predictive models previously developed by in vitro trials. Grana cheese rind blocks were inoculated with A. versicolor, P. crustosum, P. nordicum, P. roqueforti, and P. verrucosum, incubated at different T regimes (10–30 ◦C, step 5 ◦C) and after 14 days the production of mycotoxins (ochratoxin A (OTA); sterigmatocystin (STC); roquefortine C (ROQ-C), mycophenolic acid (MPA), Pr toxin (PR-Tox), citrinin (CIT), cyclopiazonic acid (CPA)) was quantified. All the fungi grew optimally around 15–25 ◦C and produced the expected mycotoxins (except MPA, Pr-Tox, and CIT). The majority of the mycotoxins produced remained in the mycelium (~90%) in three out of five fungal species (P. crustosum, P. nordicum, and P.

The objectives of this work were to study the mycoflora and mycotoxins in maize silage and investigate how agronomic practices, weather conditions and the process of ensiling affect the frequency and concentrations of several classes of mycotoxins. Silage was collected in Pennsylvania from 30-40 dairies during harvest and six months after storage in 2001 and 2002. Fusarium and Penicillium were the most commonly occurring toxigenic fungi although Aspergillus fumigatus, two Alternaria species and a novel species, Penicillium farinosum, were also present.
