• End-products of sludge-based AD were used for SCP production the first time. A potential solution to valorize underutilized products generated at WWTPs. Methylomonas dominated in mixed culture. The protein content reached 41% w/w dry weight. Several essential amino acids detected. Single cell (SCP) provides an alternative source partially replace conventional agricultural resources and suppor...

As top consumers in food chains, birds of prey forage over large geographical areas and so might be expected to accumulate environmental contaminants which are distributed in the environment. These wild animals can offer opportunities to detect and assess the toxicological effects of different inorganic elements on terrestrial ecosystems. In this study, different raptor species, both diurnal an...

We applied transmission electron microscopy and densitometric image analysis to measure the cell volume (V) and dry weight (DW) of single bacterial cells. The system was applied to measure the DW of Escherichia coli DSM 613 at different growth phases and of natural bacterial assemblages of two lakes, Piburger See and Gossenköllesee. We found a functional allometric relationship between DW (in f...

Cynara cardunculus var. scolymus L. is a herbaceous perennial plant that could be drought tolerant once established after the first year. To evaluate the effects of water stress on growth parametersand forage quality of this plant, a field experiment was conducted using a randomized complete block design with three replications in Isfahan, Iran during 2013-2015. Treatments wer...

Effects of additional nitrate (20 mol m·3 NO;) on growth of barley (Hordeum vulgare L. cv. Triumph), oat (Avena sativa L. cv. Amuri), rye (Secale cereale L. cv. Rapaki), triticale (x Triticosecale Wittm. cv. Aranui) and wheat (Triticum aestivum L. cv. Otane) prior to emergence from a sowing depth of 70 mm were examined under controlled environment. conditions. For all five cereals, additional N...

Tradescantia pallida (Wandering jew)-a succulent perennial herb-was screened to be a potent chromium (Cr) accumulator. Its ability to grow under Cr stress was examined by studying biochemical changes and physiological response of the plant in presence of 5-20 mg L(-1) Cr(VI) concentration in hydroponic environment for up to ca. 90 days. Average Cr(VI) bioaccumulation in plant roots reached abou...

The present study was carried out to determine the vitamin C content, total phenolic content (TPC), antioxidant efficacy and monomeric anthocyanin (TMAC) of twenty-one underutilized fruit species grown in Sri Lanka. Approximately 5g homogenates used while lyophilized aqueous extracts were perform in-vitro assays. Folin-Ciocalteu’s colorimetric assay TPC. 2,2-diphenyl-1-pycrylehydrazyl (DPPH) ra...

In this study, 226 Capsicum chinense genetic resources were analyzed using high-performance liquid chromatography and a spectrophotometer to measure compare their carotenoid content American Spice Trade Association (ASTA) color values, respectively. The total ASTA values of the pepper found be in range 7.04–2430.85 mg/100 g dry weight (DW) 0–221.32, Capsanthin, capsorubin, lutein, zeaxanthin, a...

Novel methods utilizing liquid chromatography-tandem mass spectrometry and gas chromatography-mass spectrometry were validated for low-level detection of 104 pharmaceuticals and personal care products ingredients (PPCPs) and four alkylphenols (APs) in environmental samples. The methods were applied to surface water, sediment, and mussel tissue samples collected from San Francisco Bay, CA, USA, ...

The fate of polybrominated diphenyl ethers (PBDEs) in sewage sludge after agricultural application was analysed. This study was based on the analysis of sewage sludge and sludge amended soil samples collected during 2005. PBDE concentrations in sewage sludge ranged from 197 to 1185ng/g dry weight (dw), being deca-BDE-209 the predominant congener. PBDE levels in soils ranged between 21 and 690ng...
