Spraying of swine buildings with lemon grass ( < em > Cymbopogon citratus < /em > ) essential oil does not produce blood absorption in swine
Cymbopogon citratus(Lemon grass)essential oils have been used in swine buildings to reduce the offensive odor emanating from swine buildings. The present study was designed to investigate plasma residues of citral which is a major constituent of the essential oils ofCymbopogon citratus.An HPLC method was established, validated and used for the determination of citral in swine plasma harvested from blood samples taken at the 14th, 21st and 28th day after spraying swine buildings with the 3% Lemon grass essential oil. Thereafter, analysis of the sample wasconductedusing HP ODS Hypersil column (200 × 4.6 mm, 5 µm) with a mo...

Isolation and Characterization of a Purple Non-Sulfur Photosynthetic Bacterium Rhodopseudomonas faecalis Strain A from Swine Sewage Wastewater.
Authors: Wei H, Okunishi S, Yoshikawa T, Kamei Y, Maeda H Abstract A purple non-sulfur photosynthetic bacterium (PNSB), PSB Strain A was isolated from swine sewage wastewater. Phylogenetic analysis revealed that PSB Strain A was most closely related to Rhodopseudomonas faecalis. Growth of the isolate under anaerobic-light conditions with a variety of carbon sources was investigated. Both PSB Strain A and the standard strain showed good growth with acetic acid, propionic acid, and n-butyric acid at a concentration of 20 mM. At the high concentration of 200 mM, PSB Strain A showed better growth in pyruvate, acetate, ...

Pretreatment of Rapeseed Meal Increases Its Recalcitrant Fiber Fermentation and Alters the Microbial Community in an in vitro Model of Swine Large Intestine
This study provides the first detailed analysis of changes in the swine intestinal microbiota due to RSM modified by ALK, CELL, PECT1, and PECT2, which altered the microbial community structure, shifted the predicted functional metagenomic profile and subsequently increased total SCFA production. Our findings that ALK, CELL, PECT1, and PECT2 increased fiber degradability in RSM could help guide feed additive strategies to improve efficiency and productivity in swine industry. The current study gave insight into how enzymatic treatment of feed can alter microbial communities, which provides good opportunity to develop novel...

Effects of three kinds of organic acids on phosphorus recovery by magnesium ammonium phosphate (MAP) crystallization from synthetic swine wastewater.
Abstract P recovery from swine wastewater has become a great concern as a result of the high demand for P resources and its potential eutrophication effects on water ecosystems. The method of magnesium ammonium phosphate (MAP) crystallization was used to recover P from simulated swine wastewater, and the effects of three organic acids (citric acid, succinic acid and acetic acid) on P removal efficiency and rate at different pH values were investigated. The results indicated that the P removal efficiency was worst affected by citric acid in the optimal pH range of 9.0-10.5, followed by succinic acid and acetic acid...

Microbial Community Analysis of Digested Liquids Exhibiting Different Methane Production Potential in Methane Fermentation of Swine Feces.
Abstract Batch methane fermentation was conducted using seed sludge collected from six methane fermentation facilities. Swine feces were centrifuged and autoclaved, followed by its use as a substrate for methanogenesis. This "swine feces supernatant medium" facilitates the cultivation of the microbes of the seed sludge, sampling of the digested liquid using a syringe, and subculturing of the digested liquid in a subsequent medium using a syringe. Through 15 subcultures, digested liquids with high and low methane production potential were obtained, which were named "H-DS" and "L-DS," respectively. On the day 10 of ...

< em > Peptoniphilus faecalis < /em > sp. nov., isolated from swine faeces
Int J Syst Evol Microbiol. 2021 Jun;71(6). doi: 10.1099/ijsem.0.004836.ABSTRACTAn obligately anaerobic, Gram-positive, non-motile, coccus-shaped bacterial strain designated AGMB00490T was isolated from swine faeces. 16S rRNA gene sequence-based phylogenetic analysis indicated that the isolate belongs to the genus Peptoniphilus and that the most closely related species is Peptoniphilus gorbachii WAL 10418T (=KCTC 5947T, 97.22 % 16S rRNA gene sequence similarity). Whole genome sequence analysis determined that the DNA G+C content of strain AGMB00490T was 31.2 mol% and moreover that the genome size and numbers of tRNA and rRN...

Fruit peel crude enzymes for enhancement of biohydrogen production from synthetic swine wastewater by improving biohydrogen-formation processes of dark fermentation
This study aims to enhance biohydrogen production from synthetic swine wastewater by employing crude enzymes obtained from different fruit peels (orange, mandarin, and banana) to improve the biohydrogen-formation processes of dark fermentation. Results indicated that dosing with crude enzymes affected volatile fatty acids (VFAs) and biogas composition insignificantly, while increased biohydrogen yield from 1.62 ± 0.00 (blank) to 1.90 ± 0.08 (orange peel), 2.01 ± 0.00 (mandarin peel), and 1.96 ± 0.01 (banana peel) mol H2/mol glucose, respectively. Banana peel crude enzyme was the most effective additive, with 1 g/L prot...

Anaerobic digestion of swine manure under natural zeolite addition: VFA evolution, cation variation, and related microbial diversity.
Abstract Batch experiments were carried out on anaerobic digestion of swine manure under 10 % of total solids and 60 g/L of zeolite addition at 35 °C. Four distinctive volatile fatty acid (VFAs) evolution stages were observed during the anaerobic process, i.e., VFA accumulation, acetic acid (HAc) and butyric acid (HBu) utilization, propionic acid (HPr) and valeric acid (HVa) degradation, and VFA depletion. Large decreases in HAc/HBu and HPr/HVa occurred respectively at the first and second biogas peaks. Biogas yield increased by 20 % after zeolite addition, about 356 mL/g VSadded with accelerated soluble che...

Application of MgO-modified palygorskite for nutrient recovery from swine wastewater: effect of pH, ions, and organic acids.
In this study, MgO-modified palygorskite (MgO-PAL) was used for simultaneous recovery of ammonia nitrogen (AN) and phosphate, and the effects of pH, ions, and organic acids on nutrient recovery were investigated. The highest removal amount of AN and phosphate separately reached 42.6 mg/g and 69.8 mg/g at pH of 9.0, 0.6 g/L dosage of modified palygorskite, and 180 min of the reaction time. MgO-PAL provided a wide range of pH (3-9) for nutrient removal. Mg released concentration was tested to investigate the removal mechanisms. The individual presence of four cations (K+, Ca2+, Na+, and Mg2+) showed negative effect on AN rem...

Compost-derived indole-3-acetic-acid-producing bacteria and their effects on enhancing the secondary fermentation of a swine manure-corn stalk composting
Chemosphere. 2021 Nov 2:132750. doi: 10.1016/j.chemosphere.2021.132750. Online ahead of print.ABSTRACTComposting, as an effectively bio-oxidative process, has been widely used for converting organic waste to organic fertilizer. However, the low fertilizer efficiency of composting product limited its application in agriculture. To improve the growth-promoting effect of composting product, the present study investigated the bioaugmentation strategy of inoculating indole-3-acetic-acid (IAA)-producing bacteria. Firstly, two IAA-producing bacteria (Bacillus safensis 33C and Rhodococcus rhodochrous YZ) were isolated from compost...
