Project description:Metagenome data from soil samples were collected at 0 to 10cm deep from 2 avocado orchards in Channybearup, Western Australia, in 2024. Amplicon sequence variant (ASV) tables were constructed based on the DADA2 pipeline with default parameters.

Project description:Dietary intake of fruits and vegetables (FV) has been inversely associated with lower risk of ulcerative colitis. A pig model was used to evaluate the impact of feeding FV on the host response to dextran sulfate sodium (DSS)-induced colitis. Methods: Six-week-old pigs were fed a grower diet alone or supplemented with lyophilized FV equivalent to the half (half-FV) or full (full-FV) daily levels recommended for humans by the Dietary Guidelines for Americans (DGA). Pigs were fed a 1) grower diet alone (negative control), 2) grower diet and orally treated with 4% DSS for 10 days to induce colitis (positive control), 3) half-FV diet treated with 4% DSS or 4) full-FV diet treated with 4% DSS. Pigs were monitored for the development of clinical signs of colitis. Proximal colon (PC) contents and mucosa (PCM) were collected for gut metagenome, tissue transcriptome and histopathological analysis. Results: Pigs fed the full-FV diet did not exhibit diarrhea, showed less fecal occult blood (FOB), PCM crypt hyperplasia but with no differential expressed genes (DEG) or changes in PC microbiome diversity (p < 0.05). Pigs within the half-FV group exhibited increased group FOB and DEG associated with tissue remodeling, crypt and goblet cell hyperplasia in the PCM and no changes in PC microbiome diversity and two pigs exhibiting diarrhea (p < 0.05). Pigs within the DSS positive control group exhibited a reduced DEG involved with intestinal immune response and PC microbiome diversity with altered metagenome, increased group PCM erosion and FOB with persistent diarrhea in one pig (p < 0.05) Conclusions: Overall, our results showed that pigs fed a three-week full-FV supplemented diet, were resistant to DSS-induced colitis with a differential dose-dependent protective effect on host intestinal tissue and gut metagenome when exposed to an inflammatory challenge.

Project description:In order to investigate how representative the recoverable proteins from charred organic residues (foodcrust) are of the food mixture cooked to produce them, a protein-rich (salmon), lipid-rich (beef fat) and carbohydrate-rich (beetroot) food were mixed, cooked and analysed. The three ingredients were mixed in 20% increments, resulting in 21 different mixtures covering all combinations of the three foodstuffs. The mixtures were placed in ceramic vessels and heated nine times with samples taken after the first, fifth and ninth heating event. Then the vessels with foodcrust were buried for 52 days and sampled again after excavation. The extracted proteins indicate substantial disparities in the relative abundance of an ingredient in the food mixture and the percentage of identified proteins it contributed. In particular salmon proteins seem overrepresented in the recovered proteome, followed by beef fat and lastly beetroot. Additionally, we found that only a limited number of proteins could be identified after the burial and that only salmon and beetroot contributed to the after burial proteomes.
