Efficacy of tannins from Mimosa pudica and tannic acid in neutralizing cobra (Naja kaouthia) venom
Provedor de dados: 80
Autores: Sia,FY; Vejayan,J; Jamuna,A; Ambu,S.
In the present study, the effectiveness of Mimosa pudica tannins (MPT) in neutralizing the lethality of Naja kaouthia venom was compared with commercially derived tannins. Preincubation of MPT with N. kaouthia venom maintained 100% survival of mice after 24 hours. The mouse group in which there was no preincubation, no protection against the effects of the venom was observed. M. pudica tannin was found to be more effective in neutralizing the lethality of N. kaouthia venom when compared to commercial tannic acid. Two protein spots were missing in the two-dimensional gel electrophoresis (2-DE) of the MPT treated mouse indicating the down-regulation of venom proteins. The results from this study indicated that tannins obtained from M. pudica are better than...

Building of Leaf Shelters by Stenoma scitiorella Walker (Lepidoptera: Elachistidae): Manipulation of Host Plant Quality?
Provedor de dados: 82
Autores: COSTA,ALEXANDRE A.; VARANDA,ELENICE M.
Building of leaf shelters is a widespread behavior among microlepidopteran larvae. Apparently, these shelters provide refuge to caterpillars against bad weather and reduce the risks of predation and parasitism. Recent studies about nutritional ecology of insects have suggested that such behavior would actually be an strategy evolutionarily selected to maximize the quality of the host plant consumed by them. Stenoma scitiorella Walker caterpillars tie together young Xylopia aromatica (Lam.) Mart. (Annonaceae) leaves to build a shelter in which they retreat, feeding exclusively on inner leaves. The accumulation of damage and excrement in leaf shelters with several caterpillars may lead to a decline in larval development and survivorship. For providing the...

Relationship between color and tannin content in sorghum grain: application of image analysis and artificial neural network
Provedor de dados: 89
Autores: Sedghi,M; Golian,A; Soleimani-Roodi,P; Ahmadi,A; Aami-Azghadi,M.
The relationship between sorghum grain color and tannin content was reported in several references. In this study, 33 phenotypes of sorghum grain differing in seed characteristics were collected and analyzed by Folin-Ciocalteu method. A computer image analysis method was used to determine the color characteristics of all 33 sorghum phenotypes. Two methods of multiple linear regression and artificial neural network (ANN) models were developed to describe tannin content in sorghum grain from three input parameters of color characteristics. The goodness of fit of the models was tested using R², MS error, and bias. The computer image analysis technique was a suitable method to estimate tannin through sorghum grain color strength. Therefore, the color quality...

Provedor de dados: 63
Autores: Theart,Jacobus Johannes Francois; Hassen,Abubeker; van Niekerk,Willem Adriaan; Gemeda,Belete Shenkute.
The nutritional value of browse foliage from the Thorny Kalahari Dune Bush veld of South Africa is not characterized. Most of this browse species is rich in tannin, but still palatable, and is consumed by ruminants during the dry season, as well as having a role to play in mitigating enteric methane emission from ruminants. In this study, the rumen methane mitigation potential of 19 browse species foliage collected from the Thorny Kalahari Dune Bush veld, was analyzed in terms of chemical composition, in vitro fermentation, digestibility and methane production. In vitro gas and methane production and organic matter digestibility (IVOMD) were determined by using rumen fluid collected, strained and anaerobically prepared. A semi-automated system was used to...

Autores: Fan,Leifa; Soccol,Andréa Thomaz; Pandey,Ashok; Vandenberghe,Luciana Porto de Souza; Soccol,Carlos Ricardo.
The objective of this work was to study the effect of caffeine and tannins on Pleurotus sp. cultivation and to evaluate the feasibility of using coffee husks as substrate for mushroom cultivation. Eight strains of P. ostreatus and two strains of P. sajor-caju were screened on a medium prepared from agar extract of coffee husk. Based on best mycelial growth and biomass production, the strain P. ostreatus LPB 09 was selected for detailed studies. With the increase of caffeine concentration, the mycelial growth and the biomass production decreased, and no growth was observed when concentration of caffeine was 2500 mg/L. Furthermore, Pleurotus did not degrade the caffeine, but absorbed it. Tannin under 100 mg/L in the medium stimulated the growth of mycelia,...
