this paper provides information on the geographic distributions of two cyprinid species: hemiculter leucisculus (basilewsky, 1855) and alburnus caeruleus heckel, 1843, in the world and the entire drainage systems in iran. the new distribution records were taken from maroon river (jarrahi river system) and chardaval river (karkheh river system), both in tigris river basin showing wide and narrow...

En este trabajo se muestran los resultados de la biosíntesis nanopartículas plata mediante el uso microalga Chlorella sp, utilizando medios crecimiento con diferentes concentraciones glicerol, entre 5% - 20%, y condiciones luz temperatura. La síntesis las estudió sobrenadantes pellets cultivos autótrofos, heterótrofos mixotróficos microalga. presencia verificó por espectroscopía ultravioleta – ...

Picochlorum soloecismus is a halotolerant, fast-growing, and moderate-lipid-producing microalga that is being evaluated as a renewable feedstock for biofuel production. Herein, we report on an improved high-quality draft assembly and annotation for the nuclear, chloroplast, and mitochondrial genomes of P. soloecismus DOE 101.

The green alga Botryococcus braunii is capable of the production and excretion of high quantities of long-chain hydrocarbons and exopolysaccharides. In this study, we present the complete plastid and mitochondrial genomes of the hydrocarbon-producing microalga Botryococcus braunii race B (Showa), with a total length of 156,498 and 129,356 bp, respectively.

Haematococcus lacustris is an industrially relevant microalga that is used for the production of the carotenoid astaxanthin. Here, we report the use of PacBio long-read sequencing to assemble the chloroplast genome of H. lacustris strain UTEX:2505. At 1.35 Mb, this is the largest assembled chloroplast of any plant or alga known to date.

The marine microalga Ostreococcus is considered to depend on the methionine synthase METH and its methylated cobalamin cofactor for methionine synthesis. Here I describe minimal media lacking both cobalt and cobalamin yet suitable for clonal growth of Ostreococcus tauri. Because Ostreococcus lacks the methylcobalamin-independent methionine synthase METE, Ostreococcus growth without cobalamin is...

The microalga Scenedesmus obliquus exhibited the ability to biodegrade dichlorophenols (dcps) under specific autotrophic and mixotrophic conditions. According to their biodegradability, the dichlorophenols used can be separated into three distinct groups. Group I (2,4-dcp and 2,6 dcp - no meta-substitution) consisted of quite easily degraded dichlorophenols, since both chloride substituents are...

Background Microalgae are uniquely advantageous organisms cultured and harvested for several value-added biochemicals. A majority of these compounds are lipid-based, such as triacylglycerols (TAGs), which can be used for biofuel production, and their accumulation is most affected under nutrient stress conditions. As such, the balance between cellular homeostasis and lipid metabolism becomes mor...
