A microcosm-based approach was used to study impacts of plant and chemical factors on the bacterial community structure of an upland acidic grassland soil. Seven perennial plant species typical of both natural, unimproved (Nardus stricta, Agrostis capillaris, Festuca ovina and F. rubra) and fertilized, improved (Holcus lanatus, Lolium perenne and Trifolium repens) grasslands were either left un...

Bacterial species capable of decolorizing textile and laboratory dyes were isolated from textile effluent treatment plant. Two bacterial strains (one Gram negative and another Gram positive bacterial strain) were screened for their ability to decolorize Red H5BL (reactive dye), Thymol blue (acid dye), Malachite green, Crystal violet (Triphenyl dye) and Congo red (azo dye). The highest decoloriz...

The perennial grasses are considered as a rich source of lignocellulosic biomass, making it a second generation alternative energy source and can diminish the use of fossil fuels. In this work, four perennial grasses Saccharum arundinaceum, Panicum antidotale, Thysanolaena latifolia, and Neyraudia reynaudiana were selected to verify their potential as a substrate to produce hydrolytic enzymes a...

Individual-based modelling (IbM) has become a fully incorporated part of predictive microbiology methodologies in the last decade. Previous studies of bacterial culture growth cycle with the IbM simulator INDISIM analysed the evolution of bacterial biomass distribution during the different phases of growth. The predicted forward shift during lag, stability during exponential and backward shift ...

UNLABELLED In this study, differing metrics were utilized to measure effects of erythromycin (ER), trimethoprim (TR) and clindamycin (CL) on the structure and function of attached Wascana Creek, SK microbial communities. All three test antibiotics, especially ER, affected community structure and function of biofilms grown in rotating annular reactors. Biofilm thickness, bacterial biomass, and l...

BACKGROUND Switchgrass is one of the most promising bioenergy crop candidates for the US. It gives relatively high biomass yield and can grow on marginal lands. However, its yields vary from year to year and from location to location. Thus it is imperative to develop a low input and sustainable switchgrass feedstock production system. One of the most feasible ways to increase biomass yields is ...

background & aim: rubiatinctorum is one of the most well-known medicinal plants whose alizarin and other anthraquinones which are outstanding color agents with some trace of pharmaceutical properties are isolated from it. the objective of this study was to optimize alizarin production in intact plant of r.tinctorum by induction with biotic elicitors. experimental: to increase the synthesis ...
