The current study is on the the use of macro-algae as feedstock for biogas production. Three types of macro-algae, Cladophora glomerata (CG), Chara fragilis (CF), and Spirogyra neglecta (SN), were chosen for this research. The experimental studies on biogas production were carried out with these algae in a batch bioreactor. In the bioreactor was maintained 35 ± 1°C temperature. The results show...

Localization of phytochrome which mediates rhizoid differentiation in Spirogyra was investigated. The red-absorbing form of phytochrome (Pr) seems to be distributed all over the cell periphery which remained in the centripetal end part after the centrifugation, as rhizoids formed equally well with red spotlight irradiation of three different parts of an end cell, i.e. distal end, middle, and pr...

Development of coal gasification plants in the United States for the generation of electrical power (SPENCER et al. 1982) may increase the probability of accidental spills of coal-derived phenols and monohydric cresol isomers into streams and rivers. Although Europe has experienced several accidental spills from coal fired electrical plants and phenol producing plants (ALABASTER et al. 1973), m...
