Lopes MM, Oliveira-Paiva CAD, Farinas CS. Modification of pectin/starch-based beads with additives to improve Bacillus subtilis encapsulation for agricultural applications. Int J Biol Macromol 2023; 246:125646. [PMID: 37394222 DOI: 10.1016/j.ijbiomac.2023.125646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 06/21/2023] [Accepted: 06/29/2023] [Indexed: 07/04/2023]
Abstract
The use of Bacillus as biofertilizer is a sustainable strategy to increase agricultural productivity, but it still requires the development of formulations to protect cells from stressful conditions. Ionotropic gelation using a pectin/starch matrix is a promising encapsulation strategy to achieve this goal. By incorporating additives such as montmorillonite (MMT), attapulgite (ATP), polyethylene glycol (PEG), and carboxymethyl cellulose (CMC), the properties of these encapsulated products could be further improved. In this study, we investigated the influence of these additives on the properties of pectin/starch-based beads for the encapsulation of Bacillus subtilis. FTIR analysis indicated pectin and Ca2+ ions interactions, while the XRD showed good dispersion of clays in the materials. SEM and X-ray microtomography revealed differences in the morphology of the beads due to the use of the additives. The viabilities at the encapsulation were higher than 1010 CFU g-1 for all formulations, with differences in the release profiles. In terms of cell protection, the pectin/starch, pectin/starch-MMT and pectin/starch-CMC formulations showed the highest cell viability after exposure to fungicide, while the pectin/starch-ATP beads showed the best performance after UV exposure. Moreover, all formulations maintained more than 109 CFU g-1 after six months of storage, which meets values required for microbial inoculants.

Abstract
Targeted delivery of drug molecules to diseased sites is a great challenge in pharmaceutical and biomedical sciences. Fabrication of drug delivery systems (DDS) to target and/or diagnose sick cells is an effective means to achieve good therapeutic results along with a minimal toxicological impact on healthy cells. Biopolymers are becoming an important class of materials owing to their biodegradability, good compatibility, non-toxicity, non-immunogenicity, and long blood circulation time and high drug loading ratio for both macros as well as micro-sized drug molecules. This review summarizes the recent trends in biopolymer-based DDS, forecasting their broad future clinical applications. Cellulose chitosan, starch, silk fibroins, collagen, albumin, gelatin, alginate, agar, proteins and peptides have shown potential applications in DDS. A range of synthetic techniques have been reported to design the DDS and are discussed in the current study which is being successfully employed in ocular, dental, transdermal and intranasal delivery systems. Different formulations of DDS are also overviewed in this review article along with synthesis techniques employed for designing the DDS. The possibility of these biopolymer applications points to a new route for creating unique DDS with enhanced therapeutic qualities for scaling up creative formulations up to the clinical level.

Abstract
Biopolysaccharides extracted from plants are mainly photosynthetic byproducts found in leaves, pods, stems, fruits, grains, seeds, corms, rhizomes, roots, bark exudates, and other plant parts. Recently, these plant-derived biopolysaccharides have received a great deal of attention as pharmaceutical excipients in a range of different dosage forms because of several key advantages, such as widespread accessibility from nature as plant-based sources are readily available, sustainable production, availability of easy and cost-effective extraction methodologies, aqueous solubility, swelling capability in the aqueous medium, non-toxicity, biodegradability, etc. The current review presents a comprehensive overview of the uses of plant-derived biopolysaccharides as effective pharmaceutical excipients in the formulations of different kinds of dosage forms, for example gels, pastes, films, emulsions, suspensions, capsules, tablets, nanoparticles, microparticles, beads, buccal formulations, transdermal formulations, ocular formulations, nasal formulations, etc.

Abstract
INTRODUCTION Metformin, an anti-diabetic drug, has low bioavailability and a short biological half-life. Thus, bioavailability enhancement and prolonged release of the drug are highly desirable. In this regard, we aimed to developed gastroretentive nanoparticles made of jackfruit seed starch (JFSS) loaded with metformin. METHODS The developed nanoparticles were optimized for various process variables and were further characterized. Nanoparticles exhibited good results with respect to particle size (244.3 to 612.4 nm), particle size distribution, shape, and drug entrapment efficiency (75.8 to 89.2 %) with sustained drug release for 24 h and a high buoyancy (89% for F7, formulation made of the highest concentration of Jackfruit seed starch prepared at 1000 RPM stirring speed). RESULTS The hypoglycemic potential of these nanoparticles was tested in the nicotinamide streptozocin induced diabetic model; there was a significant reduction in blood glucose level (50 % reduction from 4 - 8 h, p < 0.01) for a prolonged period of time (up to 24 h) in comparison to diabetic control and plain metformin solution. CONCLUSION The outcome of the study suggested that the developed formulations are suitable for gastro-retentive delivery of Metformin in a controlled manner appropriate for a single administration per day.

Abstract
Background:
Diabetes is one of the most common chronic metabolic disorders which affect
the quality of human life worldwide. As per the WHO report, between 1980 to 2014, the number of
diabetes patients increases from 108 million to 422 million, with a global prevalence rate of 8.5% per
year. Diabetes is the prime reason behind various other diseases like kidney failure, stroke, heart disorders,
glaucoma, etc. It is recognized as the seventh leading cause of death throughout the world. The
available therapies are painful (insulin injections) and inconvenient due to higher dosing frequency.
Thus, to find out a promising and convenient treatment, extensive investigations are carried out globally
by combining novel carrier system (like microparticle, microneedle, nanocarrier, microbeads etc.) and
delivery devices (insulin pump, stimuli-responsive device, inhalation system, bioadhesive patch, insulin
pen etc.) for more precise diagnosis and painless or less invasive treatment of disease.
Objective:
The review article is made with an objective to compile information about various upcoming
and existing modern technologies developed to provide greater patient compliance and reduce the undesirable
side effect of the drug. These devices evade the necessity of daily insulin injection and offer a
rapid onset of action, which sustained for a prolonged duration of time to achieve a better therapeutic
effect.
Conclusion:
Despite numerous advantages, various commercialized approaches, like Afrezza (inhalation
insulin) have been a failure in recent years. Such results call for more potential work to develop a
promising system. The novel approaches range from the delivery of non-insulin blood glucose lowering
agents to insulin-based therapy with minimal invasion are highly desirable.

Abstract
Abstract
Response surface methodology (RSM) was used to optimize rice bran oil encapsulation using jackfruit seed starch – whey protein isolate blend as wall material by spray drying technique. Oil concentration (20, 25 and 30 %), wall material (Jackfruit seed starch & whey protein isolate) starch-protein ratio (1:1, 3:1 and 5:1) and spray drying inlet air temperature (140, 150 and 160 °C) were considered as process variables for optimization. A three-factor, three-level Box-Behnken design of RSM was used to conduct the experiments with the aim of maximizing encapsulation efficiency and minimizing peroxide value in the encapsulated powder. A polynomial regression model was fitted using design expert software, and the optimum conditions obtained were 20 % oil concentration, 3:1 starch-protein ratio and 140 °C spray drying inlet air temperature. The encapsulated rice bran oil powers obtained at optimized conditions offered 85.90 % of encapsulation efficiency and 1.18 meq/kg oil of peroxide value. The characterization study revealed that powder particles size (diameter) varied from 3.40 to 300.51 µm and most of the particles were smooth spheres with little appendages.

Abstract
The utility of isolated okra (Hibiscus esculentus) gum (OG) was evaluated as a potential sustained drug release polymer-blends with sodium alginate in the development of controlled glibenclamide release ionically-gelled beads for oral use. OG was isolated from okra fruits and its solubility, pH, viscosity and moisture content were studied. Glibenclamide-loaded OG-alginate blend beads were prepared using CaCl2 as cross-linking agent through ionic-gelation technique. These ionically gelled beads showed drug entrapment efficiency of 64.19 ± 2.02 to 91.86 ± 3.24%. The bead sizes were within 1.12 ± 0.11 to 1.28 ± 0.15 mm. These glibenclamide-loaded OG-alginate blend beads exhibited sustained in vitro drug release over a prolonged period of 8 h. The in vitro drug release from these OG-alginate beads were followed controlled-release (zero-order) pattern with super case-II transport mechanism. The beads were also characterized by SEM and FTIR. The swelling and degradation of these beads was influenced by the pH of the test medium. These beads also exhibited good mucoadhesivity with goat intestinal mucosa.

Abstract
A novel dual crosslinked low-methoxyl (LM) pectinate-sterculia gum (SG) interpenetrating polymer network (IPN) beads was developed for intragastric ziprasidone delivery. The IPN beads were accomplished by simultaneous ionotropic gelation with zinc acetate and covalent crosslinking with glutaraldehyde. The effects of pectin and SG contents on drug entrapment efficiency (DEE, %), and cumulative drug release after 8h (Q8, %) were studied to optimize the IPN beads using a 3(2) factorial design. The optimized beads encapsulating ziprasidone HCl (F-O) displayed DEE of 87.98±1.15% and Q8 of 58.81±1.50% with excellent buoyancy (floating lag time <2min, % buoyancy at 8h >63%) and good mucoadhesivity with the goat gastric mucosa. In most cases, the drug release behaviour obeyed Higuchi kinetics with anomalous transport mechanism. The Zn-pectinate-SG IPN beads were also characterized by SEM, FTIR, DSC and P-XRD analyses.
