Immuno-therapies are gaining more importance to treat certain forms of cancer. The goal of therapies is to enhance person's own IgG, IgA, IgM, IgD, IgE and macrophages to combat with neoplastic cells hence the effectiveness of the immune system. Since, early civilization mushrooms are considered as potent food as well as medicine. Mushrooms are well known for their bioactive compounds such as chizophyllan, lentinan, grifolan, PSP (polysaccharide-peptide complex) and PSK (polysaccharide-protein complex) which are considered as medicines against melignancy. They prevent oncogenesis by the direct effect on tumor metastasis and exhibits antitumor effects by the induction of immune response in host. Mushroom polysaccharides have promising future for treatment of cancers due to their mode of action and efficacy. Also there are some hurdles during this treatment, but it will start a new era of safer and effective medicine based on mushroom polysaccharides.
Present study was designed to determine the microbial diversity from three distinctive sites (amended with vermicompost) of Gujarat, India. A set of 76 strains were screened from total of 438 strains that exhibit plant growthpromoting (PGP) and antagonistic potential isolated from sites PS1 (Mehsana district), BS2 (Dantiwada district) and VS3 (Gandhinagar district). Their diversity indices were studied for determining the species richness and evenness of screened isolates. Results revealed that site BS2 showed the most significant diversity indices in terms of Shannon (H 1.525) and Simpson (1/D 5.120) than other two samples. Principal component analysis showed that bacterial diversity (H ) was correlated with the soil characteristics. Chickpea and groundnut plants inoculated with MBCU1 and MBCU3 isolates showed an increase in the vegetative growth parameters that evaluate plant growth when compared to uninoculated controls. Strains MBCU1 and MBCU3 were identified as Pseudomonas stutzeri and Pseudomonas mosselii, respectively, according to sequence analysis of the 16S rRNA gene. These both isolates belong to site BS2 and they showed specific PGP traits suggesting that these isolates can promote plant growth by more than one mechanism with respect to their higher diversity index.
There are many household products like detergents, disinfectants, stain removers and cosmetics releasing chemicals that may be harmful to human health as well as cause hazardous effect on environment. Global world is now focusing on use of herbal products. They are eco-friendly and more suitable to household applications than chemicals. The present study focused on preparation of three plant-based formulations for household cleaning applications. Result showed antibacterial activity against most commonly available microbes viz. Escherichia coli and Staphylococcus aureus. This is the first report of Terminalia chebula for preparation of herbal cleaners.
A potential antagonist, designated strain Bacillus subtilis MBCU5 was previously isolated from vermicompost-amended soils of Gandhinagar, Gujarat, India. Crude allelochemicals from strain MBCU5 displayed strong antifungal activity against Macrophomina phaseolina as well as Rhizoctonia solani. These crude allelochemicals were tentatively identified as iturin, fengycin and surfactin through TLC and HPTLC analysis. Lipopeptides produced by MBCU5 were identified by MALDI-TOF-MS and LC-ESI-MS/MS analysis showed that iturin homologues (m/z 1020-1120), surfactin (m/z 1008.7 and m/z 1022.7), fengycin A and fengycin B (m/z 1400-1550) types of allelochemicals which are responsible for antifungal activity against pathogens. PCR analysis showed presence of genes (i.e. Iturin A synthetase KJ531680 and Surfactin synthetase KJ601726) involved in the biosynthesis of allelochemicals. Many reports showed lipopeptides from Bacillus species; this is the first report executed of multifarious allelochemicals from vermicompost-amended soil due to the presence of predominant Bacillus species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
