“…Oligochitosan, obtained after gamma-irradiation, was defined as a growth stimulator and anti-microbial agent for various plant systems (Muley et al, 2019a) including under conditions of drought stress (Muley et al, 2019b). Oligosaccharides (galacto-, isomalto-, fructo-, and xylo-) used as a part of alginate gel beads were reported to enhance cell viability of oral Lactobacillus fermentum and carrier stability when exposed to the specific environmental conditions (Liao et al, 2019). Similar inclusion of oligosaccharides should be expected in the near future in formulations of plant biostimulants.…”

In the last 10-15 years, the wide application of bioformulated plant beneficial microorganisms is accepted as an effective alternative of chemical agro-products. Two main problems can be distinguished in their production and application: (a) economical competiveness based on the overall upstream and downstream operational costs, and (b) development of commercial products with a high soil-plant colonization potential in controlled conditions but not able to effectively mobilize soil nutrients and/or combat plant pathogens in the field. To solve the above problems, microbe-based formulations produced by immobilization methods are gaining attention as they demonstrate a large number of advantages compared to other solid and liquid formulations. This mini-review summarizes the knowledge of additional compounds that form part of the bioformulations. The additives can exert economical, price-decreasing effects as bulking agents or direct effects improving microbial survival during storage and after introduction into soil with simultaneous beneficial effects on soil and plants. In some studies, combinations of additives are used with a complex impact, which improves the overall characteristics of the final products. Special attention is paid to polysaccharide carriers and their derivates, which play stimulatory role on plants but are less studied. The mini-review also focuses on the potential difficulty in evaluating the effects of complex bio-formulations.

“…Typically, prebiotics are indigestible or only partially digestible ingredients that stimulate the growth of probiotics in the human gut (Kolida & Gibson, 2011). For instance, the addition of oligosaccharides, such as -glucan and other plant extracts, have been shown to enhance the delivery of probiotics (Cook et al, 2014;D'Orazio et al, 2015;Liao et al, 2019;Pop et al, 2017;Yeung, Ucok et al, 2016). Oligosaccharides are not typically decomposed by enzymes in the gastrointestinal fluids but can be utilized by some bacteria, especially the Lactobacillus species in the colon.…”

“…Another approach that can be used to enhance the survival of encapsulated probiotics during storage and within the human gut is to provide them with sufficient quantities of beneficial nutrients, which can be referred to as prebiotics. Recently, it has been shown that encapsulating prebiotics within the core of microgels improves their viability without adversely affecting their release (Liao et al., ). Typically, prebiotics are indigestible or only partially digestible ingredients that stimulate the growth of probiotics in the human gut (Kolida & Gibson, ).…”

Microencapsulating Lactobacillus fermentum with oligosaccharides has recently been shown to protect probiotics to low temperatures (Liao et al., ). Psyllium and fenugreek have also been shown to be effective prebiotics that enhance the viability and growth of probiotics in the GIT (Haghshenas et al., ).…”

The potential health benefits of probiotics may not be realized because of the substantial reduction in their viability during food storage and gastrointestinal transit. Microencapsulation can be used to enhance the resistance of probiotics to unfavorable conditions. A range of oral delivery systems has been developed to increase the level of probiotics reaching the colon including embedding and coating systems. This review introduces emerging strategies for the microencapsulation of probiotics and highlights the key mechanisms of their stress–tolerance properties. Recent in vitro and in vivo models for evaluation of the efficiency of probiotic delivery systems are also reviewed. Encapsulation technologies are required to maintain the viability of probiotics during storage and within the human gut so as to increase their ability to colonize the colon. These technologies work by protecting the probiotics from harsh environmental conditions, as well as increasing their mucoadhesive properties. Typically, the probiotics are either embedded inside or coated with food‐grade materials such as biopolymers or lipids. In some cases, additional components may be coencapsulated to enhance their viability such as nutrients or protective agents. The importance of having suitable in vitro and in vivo models to evaluate the efficiency of probiotic delivery systems is also emphasized.

“…The eight commercial carbohydrates were filter sterilized by 0.22 μm filters (Bomei, Hefei, China), after which different 1% (w/v) carbon solutions were added to the CFM. The commercial carbohydrates were purchased from Yuanye Biotechnology Co., Ltd., Shanghai, China, and included the following: FOS (purity ≥95%), GOS (purity ≥90%), XOS (purity ≥95%), IMO (purity ≥90%), raffinose (purity ≥98%), stachyose (purity ≥85%), inulin (purity ≥90%) and RS (from maize, types RS3) [35]. Moreover, glucose (Glu) was used as a positive control without the addition of carbon sources as a negative control.…”

Background Bifidobacteria are important probiotics; some of the beneficial effects of bifidobacteria are achieved by the hydrolysis of glycans in the human gut. However, because the diet of breastfed infants typically lacks plant-derived glycans, in the gut environment of mothers and their breastfed infants, the mother will intake a variety of plant-derived glycans, such as from onions and bananas, through her diet. Under this assumption, we are interested in whether the same species of bifidobacteria isolated from mother-infant pairs present a distinction in their hydrolysis of plant-derived carbohydrates. Results Among the 36 Bifidobacterium strains, bifidobacterial carbohydrate utilization showed two trends related to the intestinal environment where the bacteria lived. Compared with infant-type bifidobacterial strains, adult-type bifidobacterial strains preferred to use plant-derived glycans. Of these strains, 10 isolates, 2 Bifidobacterium pseudocatenulatum (B. pseudocatenulatum), 2 Bifidobacterium pseudolongum (B. pseudolongum), 2 Bifidobacterium bifidum (B. bifidum), 2 Bifidobacterium breve (B. breve), and 2 Bifidobacterium longum (B. longum), were shared between the mother-infant pairs. Moreover, the repetitive sequence-based polymerase chain reaction (rep-PCR) results illustrated that B. pseudolongum and B. bifidum showed genotypic similarities of 95.3 and 98.2%, respectively. Combined with the carbohydrate fermentation study, these results indicated that the adult-type strains have a stronger ability to use plant-derived glycans than infant-type strains. Our work suggests that bifidobacterial carbohydrate metabolism differences resulted in the selective adaptation to the distinct intestinal environment of an adult or breastfed infant. Conclusions The present study revealed that the different gut environments can lead to the differences in the polysaccharide utilization in the same strains of bifidobacterial strains, suggesting a further goal of investigating the exact expression of certain enzymes in response to specific carbon sources.
