The endophytic green alga Acrochaete operculata completely colonizes the sporophytes of the red alga Chondrus crispus; however, it does not penetrate beyond the outer cell layers of the gametophytes. Given that the life cycle phases of C. crispus differ in the sulfation pattern of their extracellular matrix carrageenans, we investigated whether carra-geenan fragments could modulate parasite vir...

Keji beling leaves (Strobilanthes crispus) can be the solution to cure fish that infected by Aeromonas hydrophila because it contained active compounds. The purpose of this study was determine compounds in crude extract keji (S. and their ability inhibit growth A. hydrophila. tests which are used were phytochemical test, MIC disk diffusion SEM test. Phytochemicals analysis showed presence flavo...

Hexose oxidase (HOX) is an enzyme that catalyses the oxidation of C6-sugars to their corresponding lactones. A hexose oxidase enzyme produced from a nonpathogenic and nontoxigenic genetically engineered strain of the yeast Hansenula polymorpha has been developed for use in several food applications. It is encoded by the hexose oxidase gene from the red alga Chondrus crispus that is not known to...

Alien species expand their distribution by transportation network development. Hybridization between alien species Rumex obtusifolius and closely related native vulnerable species R. longifolius was examined in a mountain tourist destination in central Japan. The three taxa were morphologically identified in the field. Stem height and leaf area were greater in R. longifolius than R. obtusifoliu...

As a national key protection and restoration project, ecological of Baiyangdian Wetland has an important significance for environmental management. the research area in Zaozhadian wetland, purification effect warm season cold aquatic plants was studied under different overflying water qualities. It provides theoretical experimental basis environment management wetlands. The results showed that ...
