Rhizobia-legume symbiosis is the most well researched biological nitrogen fixation system. Coating legume seeds with rhizobia is now a recognized practical measure for improving the production of legume corp. However, the efficacy of some commercial rhizobia inoculants cannot be guaranteed in China due to the low rate of live rhizobia in these products. A greenhouse experiment was conducted to ...

Type I diabetics are dependent on daily insulin injections. A therapy capable of immunoisolating pancreatic beta-cells and providing normoglycaemia is an alternative since it would avoid the late complications associated with insulin use. Here, 3D-concave agarose micro-wells were used to culture robust pancreatic MIN-6 cell spheroids within 24 hours that were shown to exhibit cell-cell contact ...

Recently, agricultural and horticultural sectors have shown an increased interest in the use of biopolymers and their derivatives as growth biostimulators. So far, coating is a little known method of applying the biostimulators. Our three-year study investigated coating the bulbs of Ornithogalum saundersiae with chitooligosaccharide (COS), sodium alginate, carrageenan, gellan gum and xanthan gu...

Extracts from mango (Mangifera indica Linn.) cultivar Chok-Anan seed kernels were studied as active substances, since they are known as a good source of phenolic antioxidants with metal chelating and tyrosinase inhibitory activities. Response surface methodology (RSM) was used to investigate the effect of a combination of polysaccharides selected from gum arabic, maltodextrin and alginate on dr...

Objective(s): It is proposed that particulate antigens could better interact with the antigen presenting cells (APCs). A fast, simple and scalable process for preparation of polymeric nanoparticles (NPs) is coating of charged antigenic particles, like viruses, with oppositely charged polymers. A second coating with a charged polymer could increase the stability and modify the immunomodulatory p...

High-Efficiency Oil–Water Filter In article number 2100594, Jiawei Hu, Yi Chen, and co-workers prepare a high-efficiency oil–water filter by coating sodium alginate hydrogel layer in the surface of porous sand core. This exhibits excellent separation ability toward mixed liquor emulsion. Moreover, it has chemical stability, easy cleanliness, strong durability. All these characteristics make thi...

Abstract Active alginate-based coatings with quercetin glycoside and complexes of hydroxyapatite/quercetin-glycoside were used to study the shelf life fresh cut papaya stored at 6 °C. Hydroxyapatite was as a carrier for release bioactive compound. The parameters considered affecting quality fruit during storage weight loss, color, texture, sugars volatile compounds. hydroxyapatite proved higher...

In this study, dehydrated strawberries have been proposed as probiotic carriers. Strawberries were cut into halves, incorporated with Bacillus coagulans BC4 by two alternative methods (impregnation and alginate coating) submitted to drying (freeze - FD oven OD). Six treatments carried out, namely: OD (no probiotic), I-FD, I-OD, C-FD, C-OD (I- C- meaning impregnation coating respectively). While...
