Comparative studies on spectral properties of R-phycoerythrin from the red seaweeds from Qingdao

The present paper reports on comparative studies of R-phycoerythrin (R-PE) from 30 species of the red seaweeds in Bangiophyceae and in Florideophyceae from Qingdao. The measured absorption spectra show that R-PE from these red seaweeds have two spectral types, namely type I having two absorption peaks and type II having three absorption peaks. 9 specise of a lower red seaweed belonging to Bangiophyceae are all type I R-PE. 3 species of a higher red seaweed belonging to Florideophyceae are also type I R-PE. The remaining 18 species are all type II R-PE. According to the distribution of two types of R-PE in red algae, an evolutionary trend from type I R-PE to type II R-PE, can be seen, but this evolutionary process is more complicated and without a definite line of demarcation between the two spectral types of R-PE. The occurrence of two types of R-PE in red algae is of taxonomic significance. Project supported by the Science Fund of the Chinese Academy of Sciences.

The evidence from inclusions in pumices for the direct degassing of volatiles from the magma to the hydrothermal fluids in the Okinawa Trough

This article presents the evidence in support of the direct magma degassing as the principal mechanism of volatiles releasing into the hydrothermal fluids in the Okinawa Trough, as contrasted to the argument for the hydrothermal stripping of volatiles from the volcanic rocks. Laser Raman microprobe and stepped-heating techniques are employed to determine the compositions and contents of the volatiles in pumices in the middle Okinawa Trough. The results show that the volatiles are similar to the gases in the hydrothermal fluids and hydrothermal minerals in composition, the mean percent content of each component and variation trend. This indicates the direct influence of magma degassing on the hydrothermal fluid. In addition, the contents of volatiles in pumices are rather low and do not support the hydrothermal stripping as the main mechanism to enrich the fluids with gases. The results are consistent with the idea that the direct magma degassing is more important than hydrothermal stripping in supplying gases to the hydrothermal fluids in the Okinawa Trough.     

Isolation of plasmid from the blue-green algaSpirulina platensis

CCC plasmid was isolated from an economically important blue-green alga —Spirulina platensis (1.7×10⁶ dalton from the S₆ strain and 1.2×10⁶ dalton from the F₃ strain) using a rapid method based on ultrasonic disruption of algal cells and alkaline removal of chromosomal DNA. The difference in the molecular weight of the CCC DNAs from the two strains differing in form suggests that plasmid may be related with the differentiation of algal form. This modified method, which does not use any lysozyme, is a quick and effective method of plasmid isolation, especially for filamentous blue-green algae.
