All photosynthetic multicellular Eukaryotes, including land plants and algae, have cells that are surrounded by a dynamic, complex, carbohydrate-rich cell wall. The cell wall exerts considerable biological and biomechanical control over individual cells and organisms, thus playing a key role in their environmental interactions. This has resulted in compositional variation that is dependent on d...
Background & Aim: In this study, is done during one-year research on blue–green and green algae for antimicrobial activity in Mashhad suburb. Aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. Material & Methods: Amo...
biodegradation of different concentration of dye (congo red dye) by using green and blue green algae
releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...
稲葉 次郎,西 村義一,市 川竜資:放 射線医学総合研究所 環境衛生研究部 千葉市 穴川4-9-1,〒260 Co-60 metabolism/Seaweed cobalt/Rat The objective of this study is to compare whole-body retention in the rat of radiocobalt incorporated into a marine green alga with that of 60Co in inorganic form. Ulva pertusa was incubated in aerated seawater containing 60Co under fluorescent lamp for 7 days. The radio active seaweed was homogenated and...
Background & Aims: Plant extracts can change the expression of genes in cancer cells. Till now, no study has been performed on the effect of algae extract. The aim of this research was to study the changes in Bax apoptotic gene expression in glioblastoma cell line and to determine the rate of cell death in cancer cells treated with Dunalilla salina extract. U87 cell line contains glioblas...
The effects of some pretreatments including blue-green and green algae and minerals on the induction of me-tabolic and biochemical process of germination were studied in Dracocephalum kotschyi Boiss. seeds. The seeds were pretreated with green algae Spirulina platensis, Chlorella vulgaris and Dunaliella bardawil or D. IR-1 (Isolated from Gave-Khooni-salt marsh) and modified Johnson nutrient med...
Decision Algorithm of Natural Algae Coagulant Dose to Control Algae from the Influent of Water Works
Evaluation on the Phosphate Uptake Rate of Green Algae under Diurnal Rhythm and Algae Control Method
Green algae have a great potential as biofactories for the production of proteins. Chlamydomonas reinhardtii, a representative of eukaryotic microalgae, has been extensively used as a model organism to study light-induced gene expression, chloroplast biogenesis, photosynthesis, light perception, cell-cell recognition, and cell cycle control. However, little is known about the glycosylation mach...
When green hydra were starved, cell division of the symbiotic algae within their digestive cells was inhibited, but algal cell growth, measured as increase in either mean volume or protein content per cell, was not. Therefore, control of algal division by the host digestive cells must be effected by direct inhibition of algal mitosis rather than by controlling algal cell growth. The number of a...
