Fermentation of cellulase with multiple types of Salvia miltiorrhiza residues and other solid wastes from Chinese materia medica industrialization / 中国中药杂志

The solid wastes of Chinese materia dedica industrialization represented by Salvia miltiorrhiza residues have a strong small-molecule bio-recalcitrance in the process of high-value utilization of biotransformation. Highly tolerant strains were bred to break bio-recalcitrance of Salvia miltiorrhiza residues and produce high-value added cellulose, which has a significant significance for recycling and industrial utilization of solid waste. In this study, a strain of fungus, Penicillium expansum SZ13, was found with small-molecule antibacterial substance tanshinone contained in Salvia miltiorrhiza residues by a biological method. The optimal enzyme production process and peak period of SZ13 were determined. It was found that SZ13 could maintain peak enzyme production for 5 days by degrading residues under the conditions of temperature 35 ℃, rotation speed 180 r·min~(-1), 5% of residues addition, and 5% seed solution addition. Meanwhile, the ability of SZ13 to degrade the enzyme production of multiple types of residues was explored. The results showed a high enzyme activity and stable enzyme production of SZ13 in the process of degrading residues. SZ13 could efficiently utilize various types of Chinese medicine residues, such as Salvia miltiorrhiza residues, to realize the high-value utilization of cellulose in multiple types of residues.

Strategy and mode of resources circulating utilization for Chinese materia medica based on circular economy theory / 中草药

In recent years, Chinese materia medica (CMM) resources economy strongly grew with rapid development of society economy and gradual increase of health products consumption capacity, at the same time, many CMM resources deep processing enterprises were established. However, the producing pattern of most industries is the traditional mode of production with the industry characteristics of consumption of resources, low of efficiency and benefit, and high of waste emissions, which resulted in the demands for medicinal raw materials increased significantly and the medicine price raised, so the natural medicinal resources are going on the verge of exhaustion or shortage. The large scale economy has accelerated the depletion of natural resources and the replacement and compensation of resources production, which led to the generation of a huge amount of waste and environmental pressure. So how to reduce the resource consumption, improve the efficiency of resource utilization, reduce emissions, green growth, protect the ecological environment of the people has become the important problems. In this paper, based on the development status quo analysis of resources industrialization for CMM, the strategy and model of CMM resources circulating utilization has been discussed. The pattern and system of circulating utilization of CMM resources were tried to construct. These construction achievements would change the economic industry development mode and production mode of CMM resources, transform the style of economic increase of agriculture and industry of CMM. These would be contributing the achievement the mutual promotion, mutual coordination, healthy and rational circulation economy between the ecological and economic system.
