The activity of β-glucosidase in the treatment group with red mud (T) was 0.42-1.07 times higher than that in the control group without red mud (CK) from day 7 to 21 of composting. The final cellulose degradation ratios of the T (84.73%) were 10.02% higher than that of the CK (74.71%). In addition, Proteobacteria, Actinobacteria, Firmicutes, and Ascomycota were the most dominant β-glucosidase-producing microbes, and these microbes were also the phyla causing composting performances differences in the high temperature, cooling, and maturity periods of CK and T. These results indicated that adding red mud can improve β-glucosidase activity and boost the breakdown of cellulose in composting process.3-Hydroxyarginine (3-OH-Arg) is an important intermediate for the synthesis of viomycin, an important antibiotic for the clinical treatment of tuberculosis. An efficient strategy for 3-OH-Arg production based on protein engineering and recombinant whole-cell biocatalysis was demonstrated for the first time. To avoid challenging product separation due to the generation of α-ketoglutarate (α-KG) in the system, the molar ratio of the substrates L-Arg and L-Glu was optimized to ensure the efficient production of 3-OH-Arg as well as the complete consumption of α-KG. Through the establishment of a fed-batch process, 3-OH-Arg and succinic acid (SA) production reached to 9.9 g/L and 5.98 g/L after 36 h of reaction under the optimized conditions. This is the highest biosynthetic yield of 3-OH-Arg achieved to date, potentially offering a promising strategy for commercial production of hydroxylated amino acids.
