Tasco® made of sun dried brown seaweed (Ascophyllum nodosum) by Acadian Seaplants Ltd., has displayed prebiotic like properties with ruminants and may be an alternative to antibiotic growth promoters. Tasco® was fed to male broiler chickens for 35 days in a series of three trials which compared Tasco® to the prebiotic inulin and an antibiotic and determined Tasco®’s optimal inclusion level for broilers. Trials investigated Tasco® fed at 2.0% for 14 days only and examined its effects in a 45 day trial and when subjected to microbial challenge. Tasco® enhanced growth comparatively to inulin and the antibiotic virginiamycin. Alteration of physiological variables in all three trials supported the possibility of microflora changes in the gut as a mode of action. Low levels of Tasco® (0.25% and 0.5%) were consistently effective at improving growth. Microbiological profiles, currently under way, will aid in final determination of Tasco®’s qualifications as a prebiotic.

Inulin is a non-digestible carbohydrate fructan polymer consisting mainly of β (1→2) fructosyl fructose links. Enzymatic hydrolysis of inulin by inulinase results in the production of low D.P (degree of polymerization) oligosaccharides also called fructooligosaccharides(FOS). Isolation of inulin from chicory root (Chicorium intybus) was achieved by first, extraction using deionized water (600C), followed by carbonation (0.1 M Ca(OH)2 and CO2 gas). This was filtered in order to remove the non sugars, thereafter, treated successfully with polyamide 6 powder. A cation exchanger and an anion exchanger were used to further exclude other components such as tannins and pigments. The extracted inulin was quantified using the Somogyi-Nelson colourimetric assay. Chicory root (207 g, 30 % being water) yielded 30 g of the raw extract. A 100 mg of the raw extract was assayed and found to contain 11 % yield of inulin which was 80.2 % in purity and 4 % free fructose. Analysis of the crude and purified inulin extracts on the MALDI TOF spectrometry showed the samples to have a DP of 2 to 22 and 2 to 27 respectively. Maximum inulinase production from Aspergillus niger grown on inulin was observed after 60 hours. The enzyme activity was found to be 1.168 U/ml with a temperature and pH optimum of 30 °C and 7.7 respectively. The enzyme proved to be unstable as it progressively lost its total activity during attempts at purification.

Objectives: Ileal pouch anal anastomosis (IPAA), the removal of the colon and formation of a reservoir from ileum, is the surgery of choice for ulcerative colitis and familial adenomatous polyposis. Yet, 10 to 35% of patients develop pouchitis, an inflammation of the pouch mucosa. Microbial imbalances are observed in pouchitis and inulin has been suggested as a prebiotic treatment. Our objectives were to determine the effect of inulin supplementation on quality of life (QOL), and its practicality and safety as a treatment in IPAA patients.<p> Methods: Adults with IPAA (n= 8) consented to a blinded, placebo-controlled trial of inulin supplementation. Baseline symptoms were measured for 1 month prior to supplementation, followed by a blinded low-dose (5 g of inulin) or placebo (maltodextrin) for 2 weeks and a higher-dose (10 g) for 5.5 months. Participants recorded any symptoms that they experienced in a diary and QOL was assessed using the Short Inflammatory Bowel Disease Questionnaire (SIBDQ) at the beginning and end of the study.<p> Results: Two participants in the same group developed significant side effects on the 10 g supplementation; abdominal discomfort, severe gas, and small amounts of blood with defecation were reported. Unblinding determined that these participants were taking the active treatment (inulin); therefore, the study was stopped early. No differences were observed in SIBDQ scores.<p> Implications & Conclusions: In this pilot study, inulin appeared to be ineffective in improving QOL and may have contributed to unpleasant side effects. Future research should explore synbiotic therapy in IPAA, by combining prebiotics and probiotics for optimal results.
