Current investigation has for the first time utilized Trichocomaceae fungi i.e. Aspergillus niger, Aspergillus terreus, Aspergillus flavus and Pencillium i.e. Penicillium chrysogenum for augmenting the phytoremediation potential of bioenergy crops wheat (Zea mays) and ? sunflower (Helianthus annuus). Phytoremediation was done for mitigation of heavy metals i.e. Chromium (Cr), Copper (Cu), Lead (Pb) and Cadmium (Cd) from contaminated soils of agricultural significance. Phytoremediant crops were inoculated with fungal cultures by three methods i.e. mixing method, seed inoculation method and layering spreading method. Maize and sunflower plants after fungal inoculation were harvested after 60 days of germination. The estimation of % biomass and bioenergy of maize and sunflower plants was done. Results were indicative of the good phytoremediation potential of roots and shoots for uptake of heavy metals i.e. CrAspergillus niger, Aspergillus terreus and Aspergillus flavus by fungal inoculation methods. Sunflower and fungal inoculum of Aspergillus flavus and Penicillium chrysogenum extracted significant quantity of metals from the soil. By three fungal inoculation methods, range of % production of biomass was 84?87% and sunflower plants dry biomass 9.6 g yielded 0.16% of oil. Obtained results are have favored the use of fungal inoculation as an effective mode for phytoremediation augmentation of maize and sunflower. Furthermore, current work also signifies the sustainable conversion of bioenergy crops to biofuel production in a cost effective mode. 相似文献

Aflatoxin (AF) contamination was determined in 40 chili samples, representing 3 varieties from Punjab, Pakistan, by HPLC with
fluorescence detection. Total AF were determined in varieties Longi (n = 15), Wonder hot (n = 12), and Skyline 1 (n = 13), and the concentrations were high in some samples. AF were detected in 9 (60%), 8 (67%), and 7 (54%) of Longi, Wonder
hot, and Skyline 1 samples, respectively; concentration ranged from 4.7 to 34.6, 1.0 to 14.3, and 7.8 to 15.6 μg/kg, respectively.
The percentage of samples greater than the European Union statutory limit for AFB1 and total AF in spices were 53% and 53%, 53% and 8%, and 53% and 38% for Longi, Wonder hot, and Skyline 1, respectively.
Significant differences at α < 0.05 between mean concentration of AF in Longi (15.9 ± 0.6 μg/kg) and Wonder hot (5.8 ± 0.3 μg/kg)
were determined. In conclusion, choosing the variety demonstrating the lowest AF concentration from various chili samples
will assist in improving product quality. This preferred variety is Wonder Hot as described herein. 相似文献

in silico modeling, using Psipred and ExPASy servers was employed to determine the structural elements of Bcr-Abl oncoprotein
(p210BCR-ABL) isoforms, b2a2 and b3a2, expressed in Chronic Myelogenous Leukemia (CML). Both these proteins are tyrosine
kinases having masses of 210-kDa and differing only by 25 amino acids coded by the b3 exonand an amino acidsubstitution
(Glu903Asp). The secondary structure elements of the two proteins show differences in five α-helices and nine β-strands which
relates to differences in the SH3, SH2, SH1 and DNA-binding domains. These differences can result in different roles played by the
two isoforms in mediating signal transduction during the course of CML. 相似文献

Food packaging serves purposes of food product safety and easy handling and transport by preventing chemical contamination and enhancing shelf life, which provides convenience for consumers. Various types of materials, including plastics, glass, metals, and papers and their composites, have been used for food packaging. However, owing to consumers’ increased health awareness, the significance of transferring harmful materials from packaging materials into foods is of greater concern. This review highlights the interactions of food with packaging materials and elaborates the mechanism, types, and contributing factors of migration of chemical substances from the packaging to foods. Also, various types of chemical migrants from different packaging materials with their possible impacts on food safety and human health are discussed. We conclude with a future outlook based on legislative considerations and ongoing technical contributions to optimization of food–package interactions. 相似文献

Pterocarpus marsupium (Bijasal) is a valuable multipurpose forest tree. The regeneration rate in natural habitat is low and the tree is overexploited.
An in vitro propagation protocol has been developed from nodal explants obtained from in vitro raised 18-day-old axenic seedlings.
The highest shoot regeneration frequency (85%), maximum number of multiple shoots (8.6) as well as length (4.8 cm) were induced
from nodal explants on Murashige and Skoog (MS) medium amended with 4.0 μM 6-benzyladenine (BA), 0.5 μM indole-3-acetic acid
(IAA) and 20 μM adenine sulphate (AdS). The percentage of shoot multiplication as well as the number of shoots per node remained
the same during the first two subculture, afterwards a decline was recorded. Rooting was best induced in microshoots excised
from proliferated shoot cultures on semisolid hormone-free half-strength MS medium, after a pulse (dip) treatment for 7 days
in half-strength MS liquid medium containing 100 μM indole-3-butyric acid (IBA) and 15.84 μM phloroglucinol (PG). The in vitro-raised
plantlets were potted and acclimatized under culture room conditions for 4 weeks before their transfer to a greenhouse, where
the established plants showed 75% survival. 相似文献
