FIELD OF THE INVENTION The present disclosure relates to compositions and methods for enhancing the stability and survival of microorganisms in inoculant compositions. BACKGROUND OF THE INVENTION Inoculant compositions comprising agriculturally beneficial microorganisms are well known in the art. See, e.g., U.S Patent Nos. 5,484,464; 5,586,411; 5,695,541; 5,804,208; 5,916,029; 6,569,425; 6,808,917; 6,824,772; 7,429,477; 8,148,138; 8,278,247; 8,445,256; 8,883,679; 8,921,089; 8,999,698; 9,017,442; 9,101,088; 9,234,251; 9,340,464. Because the effectiveness of such inoculant compositions generally depends on the ability of the microorganisms therein to survive and propagate following application, much effort has been made to increase the stability of agriculturally beneficial microorganisms in inoculant compositions. See, e.g., U.S. Patent Nos. 8,011,132 (describing a method of adding trehalose, sucrose or glycerol to the substantially stationary phase of fermentation) and 9,090,884 (describing the microencapsulation of microorgnaisms in a water-soluble encapsulating material). Nevertheless, there remains a need for improved compositions and methods for enhancing the stability and survival of microorganisms in inoculant compositions. SUMMARY OF THE CLAIMED INVENTION The present disclosure provides compositions and methods for enhancing the survival and/or stability of microorganisms in inoculant compositions. A first aspect of the present disclosure is an inoculant composition comprising one or more maltodextrins, one or more disaccharides and one or more microorganisms. In some embodiments, the inoculant composition further comprises one or more monosaccharides, one or more oligosaccharides, one or more pesticides, one or more lipo- chitooligosaccharides, one or more chitooligosaccharides, one or more chitinous compounds, one or more flavonoids, one or more oxidation control components, one or more surfactants and/or one or more drying agents. A second aspect of the present disclosure is a kit comprising an inoculant composition of the present disclosure and a container housing the inoculant composition. A third aspect of the present disclosure is a coated plant propagation material comprising a plant propagation material and a coating that covers at least a portion of an outer surface of the plant propagation material, said coating comprising an inoculant composition of the present disclosure. A fourth aspect of the present disclosure is a kit comprising a coated plant propagation material of the present disclosure and a container housing the coated plant propagation material. A fifth aspect of the present disclosure is a plant germinated from a coated plant propagation material of the present disclosure. A sixth aspect of the present disclosure is a plant part harvested from a plant that was germinated from a coated plant propagation material of the present disclosure. A seventh aspect of the present disclosure is a processed product derived from a plant that was germinated from a coated plant propagation material of the present disclosure. An eighth aspect of the present disclosure is a crop comprising a plurality of plants germinated from coated plant propagation materials of the present disclosure. A ninth aspect of the present disclosure is a method that comprises applying an inoculant composition of the present disclosure to a plant propagation material. A tenth aspect of the present disclosure is a method that comprises, consists essentially of or consisting of planting a coated plant propagation material of the present disclosure.

Melanogenesis is the process for the production of skin-whitening agents, boosted by markets in Asian countries, melanin, which is the primary cause of human skin pigmenta- especially those in China, India and Japan, is increasing tion. Skin-whitening agents are commercially available for annually (1). Skin color is influenced by a number of intrinsic those who wish to have a lighter skin complexions. To date, factors, including skin types and genetic background, and although numerous natural compounds have been proposed extrinsic factors, including the degree of sunlight exposure to alleviate hyperpigmentation, insufficient attention has and environmental pollution (2-4). Skin color is determined by been focused on potential natural skin-whitening agents and the quantity of melanosomes and their extent of dispersion in their mechanism of action from the perspective of compound the skin (5).

Using a model of intestinal absorption, Caco-2 cell monolayer, incorporation of glabridin was examined. Glabridin was easily incorporated into the cells and released to the basolateral side at a permeability coef- ficient of 1.70Ϯ0.16 cm/sϫ105. The released glabridin was the aglycone form and not a conjugated form. Then, 10 mg (30 ␮mol)/kg body weight of standard chemical glabridin and licorice flavonoid oil (LFO) containing 10 mg/kg body weight of glabridin were adminis- tered orally to rats, and the blood concentrations of glabridin was determined. Glabridin showed a maximum concentration 1 h after the dose, of 87 nmol/L for standard glabridin and 145 nmol/L for LFO glabridin, and decreased gradually over 24 h after the dose. The level of incorporation into the liver was about 0.43% of the dosed amount 2 h after the dose.

They are classified into four types: R1 MYB, R2R3 MYB, R3 MYB and R4 MYB. GmMYB176 is an R1MYB transcription factor that regulates Chalcone synthase (CHS8) gene expression and isoflavonoid biosynthesis in soybean. Silencing of GmMYB176 suppressed the expression of the GmCHS8 gene and reduced the accumulation of isoflavonoids in soybean hairy roots. However, overexpression of GmMYB176 does not alter either GmCHS8 gene expression or isoflavonoid levels suggesting that GmMYB176 alone is not sufficient for GmCHS8 gene regulation.

Current study involves the screening and identification of potent inhibitors of the pneumococcal virulence factor pneumolysin. About 100 flavonoids were chosen from scientific literature and docked with pnuemolysin (PDB Id.: 4QQA) using Patch Dockprogram for molecular docking. The results obtained were analysed and the docked structures visualized using LigPlus software. It was found that flavonoids amurensin, diosmin, robinin, rutin, sophoroflavonoloside, spiraeoside and icariin had hydrogen bond interactions with the receptor protein pneumolysin (4QQA). Among others, robinin had the highest score (7710) revealing that it had the best geometrical fit to the receptor molecule forming 12 hydrogen bonds ranging from 0.8-3.3 Å. Keywords : Pneumococci, pneumolysin, flavonoids, antimicrobial, virtual screening _____________________________________________________________________________________________ INTRODUCTION Streptococcus pneumoniae is a gram positive pathogenic bacterium causing opportunistic infections that may be life-threating[1]. Pneumococcus is the causative agent of pneumonia and is the most common agent causing meningitis.

Many strategies have been implemented to combat this pathogen such as use of pesticides and certain agricultural practices. However, these have been largely ineffective in completely preventing P. sojae infection. An alternative strategy would be to improve the innate resistance of soybean by promoting increased glyceollin production. Glyceollins are soybean-specific antimicrobial agents which are derived from the isoflavonoid branch of the general phenylpropanoid pathway.
