Microalgae are now known as potential microorganisms in the production of chemicals, fuel, and food. Since microalgae live sea river, they need to be harvested separated cultured for further usage. In this study, separate microalgae, a bed magnetite-containing gel (Mag gel, 190 µm) was packed column by application magnetic field separative elution injected (including mainly four species), at Sa...

We investigate the dynamics of an active gel of bundled microtubules (MTs) that is driven by clusters of kinesin molecular motors. Upon the addition of ATP, the coordinated action of thousands of molecular motors drives the gel to a highly dynamical turbulent-like state that persists for hours and is only limited by the stability of constituent proteins and the availability of the chemical fuel...

Tannins gel was investigated as an adsorbent for heavy metal ions, such as lead, cadmium, copper, and others. The gel used in the present work was made by Mitsubishi Nuclear Fuel Co. Ltd. (MNF). It was found that the gel showed high adsorption capacity of heavy metal ions and the adsorption isotherms were correlated well by the Langmuir equation. The maximum adsorption capacity was influenced b...

In a microbial fuel cell (MFC), exoelectrogens, which transfer electrons to the electrode, have been regarded as a key factor for electricity generation. In this study, U-tube MFC and plating methods were used to isolate exoelectrogens from the anode of an MFC. Disparate microorganisms were identified depending on isolation methods, despite the use of an identical source. Denaturing gel gradien...

Abstract R&D program on HTGR fuel to support the RDE project has been outlined and is aimed develop national capabilities nuclear technology. The external sol-gel technology adopted for fabrication of kernels. Laboratory scale work ongoing at Center Nuclear Fuel Technology (PTBBN) BATAN study various parameters involved in process kernel including tuning related droplet formation (feed flow...

The bacterial communities in two different shoreline matrices, rocks and sand, from the Costa da Morte, northwestern Spain, were investigated 12 months after being affected by the Prestige oil spill. Culture-based and culture-independent approaches were used to compare the bacterial diversity present in these environments with that at a nonoiled site. A long-term effect of fuel on the microbial...

A microbial consortium which rapidly mineralized the environmentally persistent pollutant benzo[a]pyrene was recovered from soil. The consortium cometabolically converted [7-(14)C]benzo[a]pyrene to (14)CO(2) when it was grown on diesel fuel, and the extent of benzo[a]pyrene mineralization was dependent on both diesel fuel and benzo[a]pyrene concentrations. Addition of diesel fuel at concentrati...

Anode biofilm is a crucial component in microbial fuel cells (MFCs) for electrogenesis. Better knowledge about the biofilm development process on electrode surface is believed to improve MFC performance. In this study, double-chamber microbial fuel cell was operated with diluted POME (initial COD = 1,000 mg L(-1)) and polyacrylonitrile carbon felt was used as electrode. The maximum power densit...
