Biomass is usually considered as different types of lignocellulosic materials having varied composition potential to utilize in the useful forms energy a substitute conventional fossil fuels. Algal biomass has multi facet application research and development such source nutrients, biochemical, cosmetics biofuels. However, this newly developed met requirement low medium scale power generation du...

The use of biosorbents for heavy metal removal has revealed enormous potential of algae for biosorption. The dried biomass of Spirogyra hyalina was used as biosorbent for removal of cadmium (Cd), mercury (Hg), lead (Pb), arsenic (As) and cobalt (Co) from aqueous solutions atdifferent initial concentrations of the heavy metals and contact time of the biomass. The results showed that highest amou...

The phylogenetic branching order of the green algal groups that gave rise to land plants remains uncertain despite its fundamental importance to understanding plant evolution. Previous studies have demonstrated that land plants evolved from streptophyte algae, but different lineages of streptophytes have been suggested to be the sister group of land plants. To better understand the evolutionary...

Szucs (1913) reported that hydrogen peroxide increased the permeability of the living cell. Following up a previous observation [Bokorny, 1886], he found that if threads of Spirogyra were treated first with hydrogen peroxide and then with ferrous sulphate solutions, a dark precipitate appeared within the cells. He concluded that the hydrogen peroxide had so increased the permeability of the cel...

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...

Chloroplasts may contract under natural conditions and give up water to the rest of the cell, thus indicating changes in metabolism or constitution. Such contractions may be produced experimentally. In Nitella the chloroplasts are ellipsoid bodies which, under natural conditions, may contract to spheres with a loss of volume. This may be brought about by lead acetate, ferric chloride, and digit...
