A type II restriction endonuclease, CviBI, was isolated from a eukaryotic, Chlorella-like green alga infected with the dsDNA containing virus NC-1A. The enzyme recognizes the sequence GANTC and cleaves DNA between the G and A. Methylation of deoxyadenosine in the GANTC sequence probably inhibits enzyme activity. In vitro CviBI cleaves host nuclear DNA but not viral DNA. A survey of 18 other vir...

Plankton sangat berpengaruh terhadap keanekaragaman hidup biota karena memegang peranan sebagai komponen utama rantai makanan. Penelitian ini dilakukan untuk mengetahui dan jenis-jenis plankton di perairan Desa Rigaih. dimulai pada tanggal 10-03-2021 sampai dengan 10-04-2021. Penentuan stasiun menggunakan metode purposive sampling yang terdiri dari 4 (empat) pengamatan. Pengambilan sampel air n...

Trebouxia aggregata (Archibald) Gärtner (phylum Chlorophyta, family Trebouxiaceae), a lichen symbiotic alga, has been identified as host of the well-known herbaceous plant virus Cauliflower mosaic virus (CaMV, family Caulimoviridae). The alga had been isolated from Xanthoria parietina more than 70 years ago and has been maintained in a collection since that time. The CaMV detected in this colle...

The objective of this study was to identify the most promising nutritional mode of growth for enhanced biomass and lipid productivity in a set of twenty microalgal strains, grown under photoautotrophic and mixotrophic/heterotrophic conditions using 2% glucose as carbon source. These included four cyanobacterial strains (Cyanosarcina, Phormidium, Nostoc and Anabaena) and sixteen green algae belo...

Many reports have revealed that the abundance of microalgae in shrimp ponds vary with changes in environmental factors such as light, temperature, pH, salinity and nutrient level throughout a shrimp culture period. In this study, shrimp cultivation period was divided into three stages (initial = week 0-5, mid = week 6-10 and final = week 11-15). Physical and chemical parameters throughout the c...

Microalgae is an economical and potential raw material of biomass energy, which offer a wide range of commercial potential to produce valuable substances for applications in aquaculture feed, pharmaceutical purposes and biofuels production. However, lack of an economical, efficient and convenient method to harvest microalgae is a bottleneck to boost their full-scale application. Hence, this stu...
