Mar 31 2017 In this study we report the manganese peroxidase production ability from a Fusarium sp. strain using an inexpensive medium of agriculture residues of either rice straw or wood chips as carbon source. The highest manganese peroxidase activity on rice straw medium and on wood chips was 1.76 UmL by day 9 and 1.91 UmL by day 12 respectively.
Feb 24 2021 Screening of Catalysts. Based on these results we selected bulky manganese complexes with different amine backbones for further screening for the oxidation of aromatic C−H bonds Scheme 1. A bulky iron complex Fetips bpmcn was also included in our study. The parent complexes without any substituents on the pyridines were considered as well.
Screening can give you a jump on the disease; this lead-time is a good thing but it can bias the efficacy of screening. The two subjects to the right have the same age same time of disease onset the same DPCP and the same time of death. However if we compare survival time from the point of diagnosis the subject whose disease was .
