Livestock waste-to-bioenergy generation opportunities
TL;DR: Integration of biological and thermal-based conversion technologies in a farm-scale hybrid design by combining an algal CO2-fixation treatment requiring less than 27,000m2 of treatment area with the energy recovery component of wet gasification can drastically reduce CO2 emissions and efficiently recycle nutrients.

A review: the anaerobic treatment of sewage in uasb and egsb reactors
TL;DR: In this paper, the main characteristics of anaerobic sewage treatment are summarized, with special emphasis on the upflow anaerobically sludge blanket (UASB) reactor, with examples from Europe, Asia and the Americas.
Journal ArticleDOI
Effect of low temperature on microbial growth: lowered affinity for substrates limits growth at low temperature
TL;DR: It can be shown for psychrophiles, mesophiles and thermophiles that when a(A) is used as the measure of affinity, affinity decreases consistently as temperature drops below the optimum temperature for growth.

Treatment of sewage by a UASB reactor under moderate to low temperature conditions
Shigeki Uemura,Hideki Harada +1 more
TL;DR: The feasibility of sewage treatment by an upflow anaerobic sludge blanket (UASB) reactor was studied using actual sewage at a fixed hydraulic retention time (HRT) of 4.7 h, and at temperatures in the range of 25-13°C, for six months.
Journal ArticleDOI
Comparative structural analysis of psychrophilic and meso- and thermophilic enzymes.
TL;DR: Results reveal that each protein family adopts different structural strategies to adapt to low temperatures, and some common trends are observed: the number of ion pairs, the side‐chain contribution to the exposed surface, and the apolar fraction of the buried surface show a consistent decrease with decreasing optimal temperatures.
