While photosynthetic microalgae, such as Chlorella, serve as feedstocks for nutritional oils and biofuels, heterotrophic cultivation can augment growth rates, support high cell densities, and increase triacylglycerol (TAG) lipid content. However, these species differ significantly in their photoautotrophic and heterotrophic characteristics. In this study, the phylogeny of thirty Chlorella strai...
background and objectives: chlorophyceae are important constituents of marine phytoplankton. the taxonomy of chlorophyceae was traditionally based solely on morphological characteristics. in the present research project, genetic diversity was investigated to analyze five species of chlorophyceae from waters of the persian gulf. materials and methods: a clone library of the ribosomal small sub...
This study aimed at investigating the potential of microalgae species grown on industrial waste water as a new source of natural antioxidants. Six microalgae from different classes, including Phaeodactylum sp. (Bacillariophyceae), Nannochloropsis sp. (Eustigmatophyceae), Chlorella sp., Dunaniella sp., and Desmodesmus sp. (Chlorophyta), were screened for their antioxidant properties using differ...
ABSTRACT. The present work investigated the kinetic and thermodynamic study of adsorbents to remove copper ions from aqueous solutions compared efficiency between natural microalgae bio-adsorbent chlorella species (sp.) synthetic magnetic nanoparticles. All materials synthesized characterized by Fourier transform infrared (FT-IR), scanning electron microscope (SEM), energy dispersive X-ray (EDX...
Currently microalgae are considered as an efficient biological producer of oil.Present study was conducted to explore the lipid yield percentage three microalgal strains Chlorellasp., Oedogonium sp. and Spirogyra Bligh Dyer, Soxhlet, Folch Microwave assistedextraction methods were employed for oil extraction. It observed that Dyer method withChloroform-methanol (1:2, v/v) gave maximum extractio...
صنعت آبزی پروری در سال های اخیر، رشد فزاینده ای داشته است و تکثیر و پرورش انواع مختلف ماهیان زینتی در شرایط آکواریومی رایج گردیده است. ﺑﺮای اﻓﺰاﻳﺶ ﺗﻮﻟﻴﺪ و راﻧﺪﻣﺎن اﻗﺘﺼﺎدی در ﭘﺮورش آﺑﺰﻳﺎن، ﺗﻐﺬﻳﻪ ﻣﻨﺎﺳﺐ و اﺳﺘﻔﺎده از ﺟﻴﺮه ﻫﺎی ﻏﺬاﻳﻲ ﺑﺎ ﺣﺪاﻛﺜﺮ ﻛﺎراﻳﻲ ﺑﺮای ﻛﺎﻫﺶ هدر رفت جیره ﻏﺬاﻳﻲ و ﻫﺰﻳﻨﻪ ی تغذیه بسیار ضروری است. در این میان جلبک کلرلا میتواند به عنوان مکمل مناسبی در جیره غذایی آبزیان زینتی به کار رود...
Alfred Koch has given considerable attention to the subject of nitrogen fixation by bacteria as resulting from their symbiosis with alga~. Many others have also investigated various features of this problem. In spite of all this there are numerous questions which remain unsolved. The use of soil cultures for such studies is objectionable on account of the soil's complexity, its variety of flora...
Latest publications indicate that Cyanobacteria and green algae can play an important role in symbiosis with other organisms and can produce active compounds (classified as secondary metabolites) that inhibit the growth of pathogenic bacteria and fungi and increase plant growth. Some strains of Cyanobacteria can also assimilate atmospheric nitrogen, which enriches the soil and then is taken up ...
