For the successful operation of aerobic fermentations it is essential to supply the microorganiisms with sufficient oxygen to meet their requirements at any stage in the process. Failure to supply enough oxygen may lead to undesirable changes in enzymatic makeup (Rolinson, 1952) or death of the organisms (Hromatka et al., 1951), with a subsequent lower yield of the desired product. In general, ...

Background: Although maximal sprint speed (MSS) and the anaerobic speed reserve (ASR) provides valuable information about the speed profile of athletes, these parameters fall short of providing important information about sub-maximal metabolic thresholds. The only field test that can offer an estimate of a sub-maximal metabolic threshold is the 3-minute all-out test for running (3MT) which deli...

Abstract Nanocellulose is explored as an eco‐friendly cell modifier and reinforcer for improving the thermal insulation mechanical performance of rigid polyurethane foam (RPUF). In this study, we report on a promising method achieving ‘solvent‐free' dispersion cellulose nanocrystals (CNCs) into polyether polyol production RPUF. This was achieved through wet grinding CNC powder in agitator bead ...
