Analysis Of The Anti-Cancer Effects Of Cincau Extract (Premna Oblongifolia Merr) And Other Types Of Non- Digestible Fibre Using Faecal Fermentation Supernatants And Caco-2 Cells As A Model Of The Human Colon, Samsu U. Nurdin, Richard K. Le Leu, Graeme P. Young, James Constantine R. Stangoulis, Claus T. Christophersen, Catherine A. Abbott

Research outputs 2014 to 2021

Green cincau (Premna oblongifolia Merr) is an Indonesian food plant with a high dietary fibre content. Research has shown that dietary fibre mixtures may be more beneficial for colorectal cancer prevention than a single dietary fibre type. The aim of this study was to investigate the effects of green cincau extract on short chain fatty acid (SCFA) production in anaerobic batch cultures inoculated with human faecal slurries and to compare these to results obtained using different dietary fibre types (pectin, inulin, and cellulose), singly and in combination. Furthermore, fermentation supernatants (FSs) were evaluated in Caco-2 cells for their effect on …

Exogenous Lactobacilli Mitigate Microbial Changes Associated With Grain Fermentation (Corn, Oats, And Wheat) By Equine Fecal Microflora Ex Vivo, Brittany E. Harlow, Laurie M. Lawrence, Patricia A. Harris, Glen E. Aiken, Michael D. Flythe

Animal and Food Sciences Faculty Publications

Cereal grains are often included in equine diets. When starch intake exceeds foregut digestion starch will reach the hindgut, impacting microbial ecology. Probiotics (e.g., lactobacilli) are reported to mitigate GI dysbioses in other species. This study was conducted to determine the effect of exogenous lactobacilli on pH and the growth of amylolytic and lactate-utilizing bacteria. Feces were collected from 3 mature geldings fed grass hay with access to pasture. Fecal microbes were harvested by differential centrifugation, washed, and re-suspended in anaerobic media containing ground corn, wheat, or oats at 1.6% (w/v) starch and one of five …

Screening Of Yeast Isolates From Flowers For Effective Ethanol Production, Asma Chaudhary, Shuichi Karita

Turkish Journal of Biology

The use of alternative substrates to produce biofuel is a striking option nowadays. This study aimed to screen bioethanol-producing yeast strains. From different flowers, 65 yeasts were isolated. Twelve isolates assimilated glucose by liberation of CO2 anaerobically. Out of these, only 5 yeast isolates fermented glucose in medium consisting of 0.8 g/L Mg2+ ions to produce 2.05 $\pm$ 0.03% ethanol. The selected five strains were identified as members of the genera Metschnikowia or Meyerozyma based on molecular characterization. Selected yeast strains were used for conversion of rice into bioethanol following dilute acid hydrolysis and fermentation. Consistent ethanol production was 1.80 …

Growing Yeast For Livestock, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Over 500,000 tons of organic materials such as food scraps are disposed of each year in Wisconsin. A large percentage of this material could be composted or turned into useful products. The purpose of this article is to educate farmers and organizations on how to turn food waste into a high value food source for livestock. Yeast can be grown at any time of the year without the large inputs of agricultural chemicals and machinery that is common with other feed production methods. A yeast growing facility can be scalable to any size the producer wants such as a small …

The Use Of Lactobacillus Salivarius L28 As A Bioprotective Culture In Dry Fermented Sausages, Kathy Flynt Collins

Theses and Dissertations--Animal and Food Sciences

A challenge study to validate a 5 log₁₀ CFU/g reduction of non-O157 Shiga-toxin producing Escherichia coli (STEC) in dry fermented sausage (DFS) was performed. A 4.49 ± 0.474 log₁₀ CFU/g was achieved over two trials. The results indicated that the process was not effective in reducing the pathogen to the level required of most pathogens by the USDA.

Lactobacillus salivarius L28 (L28) was screened in vitro for the ability to inhibit STEC utilizing the paper disk diffusion method. This strain is a known bacteriocin producer. The results revealed that L28 would be a good candidate for use as …

Addition Of Molasses, Corn Steep Liquor, And Rice Polish As Economical Sources To Enhance The Fungal Biomass Production Of Wheat Straw By Arachniotus Sp., Faisal Shahzad, Muhammad Abdullah, Abdul Shakoor Chaudhry, Abu Saeed Hashmi, Jalees Ahmed Bhatti, Makhdum Abdul Jabbar, Hafiz Muhammad Ali, Tauseef Rehman, Farah Ali, Mian Muhammad Khubaib Sattar, Fayyaz Ahmed, Irfan Irshad

This study was planned to see the additive effects of various industrial residues including molasses, rice polish, and corn steep liquor for the bioprocessing of wheat straw (WS) through solid-state fermentation (SSF) using Arachniotus sp. as a fermenting agent. The performance of fungal-based WS (seed culture) was evaluated in terms of the favorable changes in crude protein (CP) contents. WS (5 g) was mixed with our selected carbon and nitrogen sources in a basal medium containing optimized salt concentrations to attain the desired level of water and nutrients. An increased (P < 0.0001) CP value was observed at a 25:1 C:N ratio and maximum fungal protein contents (13.40%) were found by mixing 0.4 mL of molasses, 0.8 g of rice polish, and 3.0 mL of corn steep liquor in treated WS at a setting time of 48 h in SSF. It was seen that the growth rate of Arachniotus sp. was greatly improved by the addition of our selected amounts of carbohydrate and nitrogen sources. Hence, our current results support the use of these economical byproducts for cheap biomass production.
