The Effect of New Zealand Kanuka, Manuka and Clover Honeys on Bacterial Growth Dynamics and Cellular Morphology Varies According to the Species
TLDR
While the general trend in effectiveness of growth inhibition was manuka>manuka-kanuka blend>kanuka>clover, the honeys had varying and diverse effects on the growth and cellular morphology of each bacterium, and each organism had a unique response profile to these honeys. Expand
Prevotella enzymes involved in mucin oligosaccharide degradation and evidence for a small operon of genes expressed during growth on mucin.
TLDR
Northern and Western analyses showed that expression of this short operon of three genes is increased during growth on mucin, and two putative genes identified which are likely to be coexpressed with this sulfatase, though their activities are unknown. Expand
In Vivo Assessment of Resistant Starch Degradation by the Caecal Microbiota of Mice Using RNA-Based Stable Isotope Probing—A Proof-of-Principle Study
TLDR
Insight is provided into the metabolic transformation of RS by intestinal bacterial communities directly within a gut ecosystem, which will finally help to better understand its prebiotic potential and possible applications in human health. Expand
In vitro Utilization of Gold and Green Kiwifruit Oligosaccharides by Human Gut Microbial Populations
TLDR
It is suggested that whole kiwifruit may modulate human gut microbial composition and metabolism to produce metabolites conducive to increased bifidobacteria-host association. Expand
Modulation of the microbial fermentation in the gut by fermentable carbohydrates
TLDR
A diet rich in varied fermentable carbohydrates such as dietary fibre, glycosylated polyphenolics, glucosinolates and other plant glycans, applied in a sustained fashion may promote microbial diversity leading to improved health. Expand
Arabinogalactan proteins contribute to the immunostimulatory properties of New Zealand honeys
TLDR
It is proposed that the immunostimulatory properties of individual honeys relate to their particular content of LPS, apalbumins, the 5.8 kDa component and AGPs, which are particularly dependent on AGPs derived from the nectar of kanuka flowers. Expand
High‐throughput microbial bioassays to screen potential New Zealand functional food ingredients intended to manage the growth of probiotic and pathogenic gut bacteria
TLDR
The surprising frequency of undesirable synergistic interactions illustrates the importance of pre-testing potential ingredient combinations intended for use in functional foods. Expand
No difference in fecal levels of bacteria or short chain fatty acids in humans, when consuming fruit juice beverages containing fruit fiber, fruit polyphenols, and their combination.
TLDR
There were no differences in fecal levels of total bacteria, Bacteroides-Prevotella-Porphyromonas group, Bifidobacteriumspecies, Clostridium perfringens, or Lactobacillus species among any of the treatment groups. Expand
Determination of Resistant Starch Assimilating Bacteria in Fecal Samples of Mice by In vitro RNA-Based Stable Isotope Probing
TLDR
The suitability of RNA-SIP to link specific groups of microorganisms with fermentation of a specific substrate is demonstrated and will help to better understand the mechanisms behind functionality of a prebiotic carbohydrate and its impact on an intestinal ecosystem with potential implications for human health. Expand
Effects of kiwifruit on innate and adaptive immunity and symptoms of upper respiratory tract infections.
TLDR
Some limited human intervention trials have been undertaken and kiwifruit has been shown to influence a number of biomarkers of oxidative stress and beneficial immune responses, to reduce the incidence and severity of symptoms of upper respiratory tract infections and potentially be more beneficial than supplementation with vitamin C alone.
