1. Introduction
Fiber consumption in the U.S. is approximately half of the recommended intake, with the average U.S. individual only consuming about 17 g/d [1]. Dietary fiber with prebiotic capacity offers a healthful, practical way to bridge the gap between consumption and recommended intake. Dietary fiber supplements can offer some of the same physiological benefits as dietary fiber found intact in foods [2]. When consumed in adequate levels, dietary fiber has been shown to help maintain a healthy body weight [3], improve cardiovascular health [4e6], support overall digestive health [7], and support the overall growth of the intestinal microbiota [8]. The intestinal microbiota have a tremendous impact on overall health, and have been recently shown to have a significant impact on the host's metabolism, immune system capacity and many other pathways affecting overall host health [9e11]. Recent studies have also found many associations between many diseases and the host's microbial composition, including: metabolic syndrome, diabetes, and many gastrointestinal diseases [12e15]. The gut microbiome and it's correlation to health and disease is a quickly revolving, dynamic area of research. Next-generation sequencing and other advanced sequencing technologies have provided new insight into this rapidly expanding field, and have allowed efficient and effective ways to analyze the thousands of diverse taxa within the human gastrointestinal tract [16,17]. Partially hydrolyze guar gum (PHGG) is a dietary fiber made from the controlled hydrolysis of guar gum, composed of both mannose and galactose monomers, and is commonly consumed as both a dietary fiber supplement, as well as in foods. PHGG has been shown to alleviate irritable bowel syndrome (IBS) due to its nongelling effects [18] and has been shown in randomized, cross-over clinical studies to increase satiety [19,20]. In a four-week clinical feeding study where participants consumed 20 g/d of PHGG researchers found an overall decrease in total serum cholesterol, an increase in fecal weight and a lower fecal pH without influencing key nutrient absorption. In vitro models have shown that PHGG supports the growth of Bifidobacterium and Lactobacillus, two genera of bacteria that have been associated with many health outcomes [21,22]. This paper is a follow-up of previously published work from our laboratory that evaluated the differences in fermentation rates between six individuals' fecal microbiota all exposed to PHGG in an in vitro fermentation model, with the primary objective of showing the differences in short chain fatty acid (SCFA) synthesis and total gas production, and found over a 2-fold difference in total SCFA production in 24 h [23]. The current study has the objective of determining key changes and individual differences among six individual's fecal microbiota exposed to PHGG in an in vitro fermentation model. To the authors' knowledge, this is the first in vitro model with six individuals to show the short-term effects of PHGG on the fecal microbiota.
