The aim of the study was to investigate the potential prebiotic effects of food-by-products (cassava bagasse (n=3), orange bagasse (n=2) and passion fruit peel (n=3)) using an in vitro model simulating the proximal colon, and to assess possible differences in fermentation when using faecal microbiota from lean or obese people. Fermentation of the by-products was compared to a control medium and the prebiotic inulin. The effects of the by-products on the dynamics of the gut microbiota differed according to the type of microbiota, as well as the type of by-product used. Principal Coordinate Analysis of the microbiota showed evidence of a clear separate clustering of lean and obese microbiota before the addition of substrates, which disappeared after fermentation, and instead, distinct clusters due to primary carbohydrate composition of the by-products (starch, fructan and pectin) were present. This is evidence that the substrates drove the obese microbiota to a healthier profile, more similar to that of the lean microbiota. Cassava bagasses enriched the beneficial genus Bifidobacterium in the obese microbiota. The production of total SCFA by cassava bagasses by the obese microbiota was higher than for control medium and inulin. Orange bagasses stimulated the growth of the butyrate-producing genus Coprococcus. Passion fruit peels were poorly fermented and generated negligible amounts of intermediate metabolites, indicating slow fermentation. Nevertheless, passion fruit peel fermentation resulted in a microbiota with the highest diversity and evenness, a positive trait regarding host health. In conclusion, the use of food-by-products could be an important step to tackle obesity and decrease the waste of valuable food material and consequently environmental pollution. They are an inexpensive and non-invasive way to be used as a dietary intervention to improve health, as they were shown here to drive the composition of the obese microbiota to a healthier profile.

<div class="WordSection1"><p class="Abstrak"><span lang="EN-GB">Part of the cassava that can be used as a food product is usually starch and and the waste is cassava bagasse. Fermented cassava bagasse flour is a modified semi-solid fermentation product using yeast <em>Saccharomyces</em> <em>cerevisiae </em>which has almost the same quality as modified cassava flour (mocaf), but fermented cassava bagasse flour has advantages compared to mocaf flour, namely high protein content and cheaper production costs. Fermented cassava bagasse flour has various functions which can be used as raw material for the manufacture of various processed products, one of which is cassava stick. The research objective was to see the formulation of fermented cassava bagasse flour to the sensory characteristics of the resulting cassava stick. The study was conducted using a completely randomized design (CRD) including 5 treatment methods, namely cassava starch substituted by fermented cassava bagasse flour 5% (B1), 10% (B2), 15% (B3), 20% (B4) and 25% (B5), each treatment was repeated 3 times. Based on the sensory results, it was obtained that 15% (B3) fermented cassava bagasse flour substitution treatment was the best choice of cassava stick product by panelists. The results of the analysis of cassava stick products were hardness test 3,77 µ (kg / cm<sup>2</sup>) ; swelling ratio 18,33% ; moisture content 2,20% ; ash content 0,14% ; protein content 10,00% ; fat content 21,00% ; fiber content 0,17%; carbohydrate content 66,49% and total dietary fiber 21,24%.</span></p></div>

Abstract The agricultural industries generate lignocellulosic wastes that can be modified by fungi to generate high value-added products. The aim of this work was to analyze the efficiency of the bioconversion of sugarcane bagasse and cassava bagasse using two cheap home-made enzymatic cocktails from Aspergillus niger LBM 134 (produced also from agroindustrial wastes) and compare the hydrolysis yield with that obtained from the bioconversion using commercial enzymes. Sugarcane bagasse and cassava bagasse were pretreated with a soft alkaline solution before the hydrolysis carried out with home-made enzymatic cocktails of A. niger LBM 134 and with commercial enzymes to compare their performances. Mono and polysaccharides were analyzed before and after the bioconversion of both bagasses as well as their microscopic structure. The maximal yield was the 80% of total glucans saccharified from cassava bagasse. The bioconversion of both bagasses were better when we used the home-made enzymatic cocktails than commercial enzymes. We obtained high added-value products from agroindustrial wastes, home-made enzymatic cocktails and hydrolysates rich in fermentable sugars. The importance of this work lays in the higher performance of the cheap home-made enzymatic cocktails over the hydrolytic performance of commercial enzymes due to the cost of producing the home-made enzymatic cocktails were more than 500 times lower than commercial enzymes.

Ecuador is an agricultural country, which has an actual production of starch obtained from cassava. Tuber processing residues do not have an economic impact; for example, the cassava bagasse, only used for plant fertilization and animal feeding. This project aimed to study the influence of the fermentation variables (pH and agitation), on the lactic acid production. Enzymatic hydrolysis of cassava bagasse starch for the varieties INIAP 650 and INIAP 651 was performed using α-amylase and glucoamylase. Then, glucose was fermented by Lactobacillus leichmannii ATCC 7830 strains, varying conditions such as agitation (150 rpm and absence) and pH (4.5, 5.0, and 5.5). Finally, the determination of lactic acid was performed by potentiometric and FTIR analysis. Conversions of cassava bagasse to reduced sugars were 71.66 and 85.05 % for INIAP 650 and INIAP 651 varieties. The best lactic acid concentrations were 27.62 and 33.48 g/L, obtained at pH 5.5 and agitation, for INIAP 650 and INIAP 651 varieties. Qualitative analysis conducted by FTIR spectrophotometry confirmed the presence of lactic acid in the reacted products. Lactic acid production from cassava bagasse starch could contribute to the Manabí and Esmeraldas provinces of Ecuador's economic development.
