The filamentous cyanobacterium Arthrospira platensis strain MMG-9 was isolated from a rice field. The ability of this strain to synthesize the bioactive compound indole-3-acetic acid (IAA) was demonstrated. IAA was extracted from the culture A. platensis strain MMG-9 and its identity was confirmed by thin layer chromatography (TLC) as well as by high(More)
Cyanobacteria have the ability to form associations with organisms from all domains of life, notably with plants, which they provide with fixed nitrogen, among other substances. This study was aimed at developing artificial associations between non-heterocystous cyanobacteria and selected crop plants. We isolated several non-heterocystous cyanobacteria from(More)
A variety of microscopic techniques have been utilized to study cyanobacterial associations with plant roots, but confocal laser scanning microscopy (CLSM) is the least used due to the unavailability of a suitable fluorescent dye. Commonly used lectins have problems with their binding ability with root cells and their visualization under CLSM. DTAF(More)
Alzheimer's disease (AD), a big cause of memory loss, is a progressive neurodegenerative disorder. The disease leads to irreversible loss of neurons that result in reduced level of acetylcholine neurotransmitter (ACh). The reduction of ACh level impairs brain functioning. One aspect of AD therapy is to maintain ACh level up to a safe limit, by blocking(More)
The genus Leptolyngbya comprises filamentous cyanobacteria that are important in rice fields. In the rhizosphere, cyanobacteria produce a variety of secondary metabolites such as auxins that are important in agriculture soil performance. To assess this, Leptolyngbya strain MMG-1, was isolated from the rhizosphere of rice plants and described. For this, the(More)
Macroalgae belonging to the genus Padina are known to produce antibacterial compounds that may inhibit growth of human- and animal pathogens. Hitherto, it was unclear whether this antibacterial activity is produced by the macroalga itself or by secondary metabolite producing epiphytic bacteria. Here we report antibacterial activities of epiphytic bacteria(More)
AIMS The aim of the present study was to analyze As transformation and biosorption by indigenous As resistant bacteria both in planktonic and biofilm modes of growth. METHODS AND RESULTS As resistant bacteria were isolated from industrial waste water and strain PT2, identified as Exiguobacterium profundum through 16S rRNA gene sequencing was selected for(More)
To achieve sustainable economic growth of a country balanced budget is not only important but necessary. This research aims at investigating the true impact of the budget deficit on the economic growth of the country. The sample taken for the current study comprises of time-series considering period of 1978-2009. Regression analysis is conducted to(More)
Polyketides are complex and diverse secondary metabolites, synthesised by large multifunctional enzymes, Polyketide Synthases (PKS). The phylogenomic analysis of β-ketosynthase (KS) domains and PKSs within actinomycetes suggests the contribution of point mutations, gene duplications, horizontal gene transfer and homologous recombination in the evolution of(More)
The aim of this study is to investigate the pre and post reform poverty reduction in Pakistan. A consistent time series of poverty estimates from 1964-2006 has been developed in order to facilitate the analysis of poverty trends, together with data on income inequality. This research has attempted to analyze Pakistan’s poverty and inequality statistics in(More)
