Abstract The aim of this study was to find alternatives (even partial) mineral nitrogen fertilization reduce its harmful accumulation in the edible parts fennel. Fennel ( Foeniculum vulgare ) is a perennial plant Apiaceae family grown for shoots, leaves, and seeds. present work conducted two successive seasons, 2018/2019 2019/2020, at farm Agricultural Botany Department, Faculty Agriculture, Ai...

Spirulina platensis, simbiyotik, çok hücreli ve ipliksi yap?da mavi-ye?il bir mikroalgdir. Esansiyel amino asitler, ?-karoten, fikobiliproteinler gibi pigmetler eikosapentaenoik asit (EPA) dokosaheksaenoik (DHA) çoklu doymam?? ya? asitleri baz? yüksek de?erli biyoaktif moleküller aç?s?ndan zengindir. Ayr?ca, protein içeri?i (kuru a??rl?kta %60-70) ile önemli kaynaklar?ndan biridir. Bu çal??mada...

The interaction of Zn(II) ions with cyanobacteria Spirulina platensis basic protein C-phycocyanin (C-PC) is studied by fluorescence spectroscopy.Stern–Volmer quenching constant value for Zn(II)–C-PC is determined. The binding energy of Zn(II) ions with C-phycocyanin is determined using equilibrium dialysis and atomic absorption spectroscopy. Cooperative binding of Zn(II) ions with C-phycocyanin...

The influence of culture temperature and the concentration of sodium nitrate (NaNO3) on the gas-chromatographic profile of the fatty acids of the filamentous cyanobacterium Spirulina platensis was evaluated. We found that temperature was the most important factor and that the greatest amount of gamma-linolenic acid (GLA) was obtained at 30 degrees C, the fatty acid profile of the Spirulina cult...

This study explores the influence of wastewater feedstock composition on hydrothermal liquefaction (HTL) biocrude oil properties and physico-chemical characteristics. Spirulina algae, swine manure, and digested sludge were converted under HTL conditions (300°C, 10-12 MPa, and 30 min reaction time). Biocrude yields ranged from 9.4% (digested sludge) to 32.6% (Spirulina). Although similar higher ...

  This experiment was carried out in Bandargah Station in Bushehr province. Peneaus semisulcatus larvae were fed on Spirulina platensis as supplementation microalgae. In order to use spirulina platensis in this study, we have to produce biomass and dry production of this microalga. Determination of length and survival rate of Peneaus semisulcatus larvae was carried out as the objective of the s...

Phytoplankton constitutes the primary producers of aquatic ecosystems and represents the food chain base that supports the commercial fisheries of most water bodies. Nowadays, there is lack of information on phytoplankton assemblages of most reservoirs in Africa. To contribute with this knowledge, this study was carried out to determine the density and diversity of seasonal variations of phytop...
