Subject:
Clostridium; arabinose; bacterial culture; bioreactors; cellobiose; hydrogen production; hydrolysates; lignocellulose; pH; xylose
Abstract:
... This study assessed the effect of hydraulic retention time (HRT) ranging from 24 to 3 h on continuous dark-fermentative H₂ production in four bioreactors operated at pH 5.0, 5.5, 6.0 and 6.5. A mixture of cellobiose, xylose and arabinose was used as the substrate. The highest hydrogen production rate between HRTs of 24 and 12 h was observed at pH 6.5, while at HRT below 12 h at pH 6.0. At a HRT of ...

Subject:
bacterial culture; batch fermentation; food waste; goat cheese; inoculum; milk; pH; pet foods; propionic acid; temperature
Abstract:
... In this study, lab-scale batch fermentation tests were carried out at mesophilic temperature (30 °C) to examine the influence of inoculum type, pH-value, and thermal pretreatment of substrate on propionic acid (PA) production from dog food. The selected inocula comprised a mixed bacterial culture, milk, and soft goat cheese. The batch tests were performed at pH 4, pH 6, and pH 8 for both, untreate ...

Subject:
Chlorella; algae culture; ambient temperature; bacterial culture; microalgae; photobioreactors; viability
Abstract:
... Two outdoor photobioreactors were operated to evaluate the effect of variable ambient temperature on an indigenous microalgae-nitrifying bacteria culture dominated by Chlorella. Four experiments were carried out in different seasons, maintaining the temperature-controlled PBR at around 25 °C (by either heating or cooling), while the temperature in the non-temperature-controlled PBR was allowed to ...

Abstract:
... The present work studied to evaluate the effectiveness under the interaction of bacterial consortium and biochar applied to give impetus to bacterial community activities among cow manure composting. High-throughput sequencing technique and six treatments were carried out: T2, T3 and T6 were single apply of bacteria culture (C), 12%wood biochar (12%WB) and 12%wheat straw biochar (12%WSB), respecti ...
