Organic acids production from starch waste by rumen microorganisms

Organic acid production from potato starch waste fermentation by rumen microbial communities from Dutch and Thai dairy cows.

Project description:BackgroundExploring different microbial sources for biotechnological production of organic acids is important. Dutch and Thai cow rumen samples were used as inocula to produce organic acid from starch waste in anaerobic reactors. Organic acid production profiles were determined and microbial communities were compared using 16S ribosomal ribonucleic acid gene amplicon pyrosequencing.ResultsIn both reactors, lactate was the main initial product and was associated with growth of Streptococcus spp. (86% average relative abundance). Subsequently, lactate served as a substrate for secondary fermentations. In the reactor inoculated with rumen fluid from the Dutch cow, the relative abundance of Bacillus and Streptococcus increased from the start, and lactate, acetate, formate and ethanol were produced. From day 1.33 to 2, lactate and acetate were degraded, resulting in butyrate production. Butyrate production coincided with a decrease in relative abundance of Streptococcus spp. and increased relative abundances of bacteria of other groups, including Parabacteroides, Sporanaerobacter, Helicobacteraceae, Peptostreptococcaceae and Porphyromonadaceae. In the reactor with the Thai cow inoculum, Streptococcus spp. also increased from the start. When lactate was consumed, acetate, propionate and butyrate were produced (day 3-4). After day 3, bacteria belonging to five dominant groups, Bacteroides, Pseudoramibacter_Eubacterium, Dysgonomonas, Enterobacteriaceae and Porphyromonadaceae, were detected and these showed significant positive correlations with acetate, propionate and butyrate levels.ConclusionsThe complexity of rumen microorganisms with high adaptation capacity makes rumen fluid a suitable source to convert organic waste into valuable products without the addition of hydrolytic enzymes. Starch waste is a source for organic acid production, especially lactate.

Unveiling distinct storage composition and starch properties in developing indica rice grains via transcriptional profiling and enzymatic activity analysis

Project description:Recently, we observed significant differences in the starch molecular composition and structure between the two Thai indica rice cultivars, RD6 and RD57. However, a comprehensive understanding of the transcriptional regulation of their storage polymers, remains lacking. To address this, we investigated the gene expression patterns and enzymatic activities of key starch and storage protein biosynthetic enzymes in the developing endosperms of these cultivars. The transcriptional profiles of waxy RD6 and high-amylose RD57 rice endosperms were analyzed at 7, 14, 21, and 28 days post-anthesis (DPA). The expression patterns of major differentially expressed genes (DEGs) were cross validated with enzymatic activities and the grain starch and storage protein compositions. Gene expression profiles varied significantly between the RD6 and RD57 rice cultivars, with the most distinct differences observed at 14 days post-anthesis (DPA) and the least at 28 DPA. Temporal dynamics of transcriptome profiles among genes in starch and storage protein biosynthesis revealed active gene expression at 14 DPA and 7 DPA. Collectively, this study provided a comprehensive understanding of the biosynthesis of storage biomolecules through transcriptional profiling of the Thai indica rice. For the breeding and developing new Thai commercial rice varieties with targeted ECQ and health-beneficial traits, understanding the regulatory mechanisms that control starch and storage protein accumulation at both transcriptional and post-translational levels is crucial.

Effects of starters with different NDF/starch ratio on rumen fermentation parameters and rumen microorganisms in lambs.

Project description:Starch and NDF are the main components in the diets of ruminants worldwide and are the main energy source for rumen microorganisms and hosts. The purpose of this study was to investigate the effects of different NDF/starch ratios on rumen fermentation parameters, rumen development and rumen microbes in lambs and to predict the function of rumen microbes by metagenomic techniques. In this study, 30 lambs with birth weights of (3.0 ± 0.5) kg were selected. The lambs of Hu sheep were randomly divided into two groups, fed starter with an NDF/starch ratio of 0.5 (group A) or 1.0 (group C). Samples of the rumen tissue and contents were collected after slaughter. The results showed that the ADG and ADFI of group A were significantly higher than those of group C (P < 0.05), but there was no significant difference in the FCR (P > 0.05). Therefore, from the perspective of feed-related economic benefits, group C showed greater economic value; the A/P of group C was significantly lower than that of group A (0.05 < P < 0.1), and the TVFA showed no significant difference (P > 0.05); The lengths of the rumen papillae of group C was significantly higher than that of group A (0.05 < P < 0.1). There was no significant difference in the abundance of the top 10 species at the phylum level and genus level (P > 0.05). CAZymes gene enrichment was observed in the rumen microbial community of lambs in group C (P < 0.05). In conclusion, group C, fed with starter with a higher NDF/starch ratio, had a higher feeding value. This study provides comprehensive insights into the composition of NDF and starch in lamb starter.

Immunomodulatory Potential of Dapphitkhai and Chanthaleela Thai Traditional Recipes in the Context of COVID-19 Pathogenesis

Project description:This study aimed to investigate the effects of two Thai traditional recipes including Dapphitkhai and Chanthaleela on various immune parameters and signaling pathways in human white blood cells. The gene expression of whole blood stimulation was analyzed through RNA-sequencing and pathway analysis. Chanthaleela and Dapphitkhai demonstrated a significant decrease in IL-8 secretion and an increase in IFN-β secretion, suggesting their potential to modulate these signaling pathways. Gene expression analysis of Chanthaleela and Dapphitkhai at 500 µg/mL revealed distinct patterns and identified differentially expressed genes. Gene ontology analysis highlighted the impact of the recipes on immune responses and cytokine regulation, while pathway analysis identified key pathways related to cytokine-cytokine receptor interaction, chemokine signaling, and infection-related processes. This study provides valuable insights into the effects of Thai traditional recipes on immune parameters and signaling pathways in human white blood cells. The findings suggest potential therapeutic applications of Thai traditional medicine in immune-related disorders and viral infections like COVID-19.

Genomic hybridization of Methanobacteria to identify the diversity in strains on manure and olive mill waste.

Project description:Population dynamics of methanogenic genera was investigated in pilot anaerobic digesters. Cattle manure and two-phase olive mill wastes were codigested at a 3:1 ratio in two reactors operated at 37 ï¾°C and 55 ï¾°C. Other two reactors were run with either residue at 37 ï¾°C. Sludge DNA extracted from samples taken from all four reactors on days 4, 14 and 28 of digestion was used for hybridisation with the AnaeroChip, an oligonucleotide microarray targeting those groups of methanogenic archaea that are commonly found under mesophilic and thermophilic conditions (Franke-Whittle et al. 2009, in press, doi:10.1016/j.mimet.2009.09.017).
