Optimization of hydrogen production using a coculture of Chlamydomonas reinhardtii and activated sludge bacteria.

The production of biophotolytic hydrogen (H) relies on the effective management of oxygen (O) levels. Coculturing bacteria with microalgae helps mitigate the excess O produced by algal cells. After depleting O, the bacteria activate the enzyme hydrogenase in microalgae, leading to H production.

ASSESSING ORONASAL FISTULA RATES: MINIPLATE AS EXTERNAL FIXATOR VS ANTERIOR NASAL SPINE PLATING FOR PALATAL FRACTURES.

Background: Palate, a midface bone, shapes the face and supports buttresses. Palatine process of maxilla and horizontal plate of palatine bone constitute it. Palatal bone is thicker anteriorly and laterally than posteriorly and centrally.

Photo fermentative biohydrogen production potential using microalgae-activated sludge co-digestion in a sequential flow batch reactor (SFBR).

Biohydrogen (bioH) is a sustainable energy source that can produce carbon-free energy upon combustion. BioH can be generated from microalgae by photolytic and anaerobic digestion (AD) pathways. The AD pathway faces many challenges when scaling up using different bioreactors, particularly the continuous stirred tank reactor (CSTR) and sequential flow batch reactor (SFBR).

Biodesalination using halophytic cyanobacterium Phormidium keutzingianum from brackish to the hypersaline water.

The biodesalination potential at different levels of salinity of Phormidium keutzingianum (P. keutzingianum) was investigated. A wide range of salinity from brackish to hypersaline water was explored in this study to ensure the adaptability of P.

Unprecedented biodesalination rates-Shortcomings of electrical conductivity measurements in determining salt removal by algae and cyanobacteria.

Phormidium keutzingianum performed biodesalination of brackish water (10 g/L). The electrical conductivity (EC) was measured to evaluate the salt concentration over 80 days of cyanobacterial inoculation. Anion concentrations were measured using ion chromatography to estimate salt removal.
