all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...

Actinomycetes are inexhaustible producers of commercially valuable metabolites, are continually screened for beneficial compounds. The taxonomic and phylogenetic study of novel actinomycetes strains are mostly based on conventional methods and primary DNA structure of 16s rRNA. Although 16s rRNA sequence is well accepted in phylogeny studies, its secondary structures have not been widely used. ...

Background: The present study represents a preliminary analysis of genetic diversity among Passiflora species using amplified genotypic data specific ITS and rbcL sequences non-specific RAPD-PCR markers for investigation the molecular phylogeny.
 Methods: PCR-RAPD uses ten primers polymorphic DNA, which are compiled on NTSYS software to construct dendrogram. gene used amplification from ge...

Biodiversity of phylloplane and endophytic fungi have been considered as one of the rich source of novel natural compounds of biological activities and a high level of structure diversity on the leaf surfaces. Bioactive components produced by phylloplane and endophytes have shown promising potentiality towards human health. In this juncture, it is necessary to understand and manipulate this imp...

This study investigated the influence of Trichoderma asperellum on active oxygen production in maize seedlings under saline-alkaline stress conditions. Two maize cultivars were tested: 'Jiangyu 417' ('JY417'), which can tolerate saline-alkaline stress; and, 'Xianyu 335' ('XY335'), which is sensitive to saline-alkaline stress. The seedlings were grown on natural saline-alkaline soil (pH 9.30) in...

Turtles are currently the most endangered major clade of vertebrates on earth, and Asian box turtles (Cuora) are in catastrophic decline. Effective management of this diverse turtle clade has been hampered by human-mediated, and perhaps natural hybridization, resulting in discordance between mitochondrial and nuclear markers and confusion regarding species boundaries and phylogenetic relationsh...

BACKGROUND Environment pollution by heavy metals is a global disaster and there are several cleaning methods including bioremediation. Trichoderma species inhibit the growth of pathogenic fungi and play a useful role in agriculture and ecosystem management. METHODS In this study, the removing of cadmium ions by three species of Trichoderma (T. asperellum, T. harzianum and T. tomentosum) were ...
