“…There have been continuous efforts in improving the functional performance of probiotics in gastro-intestinal tract using dietary ingredients known as prebiotics. These are non digestible ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of bacteria in colon that can improve host health (Gibson and Roberfroid 1995;Liong 2008;Stoyanova et al 2010). Non-digestible carbohydrates, oligo-and poly-saccharides, occur naturally and meet the criteria of prebiotics (Ziemer and Gibson 1998).…”

Synbiotics offer potential in the prophylactic management of gastrointestinal disorders. Therefore, present study evaluates the effect of prebiotics (inulin and gum acacia) on Lactocaillus plantarum for developing a freezedried synbiotic product from the selected culture. L. plantarum exhibited the highest specific growth rate (0.23/h) in presence of inulin followed by gum acacia (0.22/h) and glucose (0.22/h). Preparation of the lyophilized synbiotic powder incorporating inulin or gum acacia and using non fat dry milk as base material was standardized. Throughout refrigerated storage for 90 days, viable counts (i. e. 8 to 9 log cfu/g) of the probiotic bacteria in the product remained high, while a considerable reduction in the counts was observed in the product stored at room temperature (25±1°C).

“…The outcome of the in vitro experiment suggests that the presence of oxidized oligosaccharides could be diagnostic for ROS scavenging activity in planta. Prior experiments (Stoyanova et al, 2011) have shown that inulin polysaccharides and 1-kestose are efficient ROS scavenging molecules. Inulin is a more effective scavenger than a number of phenolic compounds .…”

Barley (Hordeum vulgare) grain development follows a series of defined morphological and physiological stages and depends on the supply of assimilates (mainly sucrose) from the mother plant. Here, spatio-temporal patterns of sugar distributions were investigated by mass spectrometric imaging, targeted metabolite analyses, and transcript profiling of microdissected grain tissues. Distinct spatio-temporal sugar balances were observed, which may relate to differentiation and grain filling processes. Notably, various types of oligofructans showed specific distribution patterns. Levan-and graminan-type oligofructans were synthesized in the cellularized endosperm prior to the commencement of starch biosynthesis, while during the storage phase, inulin-type oligofructans accumulated to a high concentration in and around the nascent endosperm cavity. In the shrunken endosperm mutant seg8, with a decreased sucrose flux toward the endosperm, fructan accumulation was impaired. The tight partitioning of oligofructan biosynthesis hints at distinct functions of the various fructan types in the young endosperm prior to starch accumulation and in the endosperm transfer cells that accomplish the assimilate supply toward the endosperm at the storage phase.

“…Hydroxyl radical antioxidant capacities were 9 characterized by amounts of plant samples needed to decrease HTPA fluorescence (315 nm excitation, 420 nm emission) by 50% as described earlier (Stoyanova et al 2011) and were given as µM ethanol equivalent mg -1 leaf fresh weight.…”
