Waste Degradation

The current study was carried out for the purpose of comparative evaluation of vegetable market waste degradation potential of three earthworm species (Eisenia fetida, Perionyx excavatus and Eudrilus eugeniae). The vegetable waste used as substrate in this study was collected from Mission Chariali vegetable market in Tezpur, Assam, India. Non-biodegradable materials such as polythenes, plastic etc. were segregated and organic waste was sun-dried. Cow dung was mixed with the substrate in 1:3 proportion and subjected to vermicomposting with three earthworms species separately. The data on physicochemical properties of the compost bed along with earthworm activity were collected every 10 days interval. The experiment was continued until 70 days. Analysis of the data indicated that E. fetida posed maximal nutrient mineralization and reduction in C:N ratio when compared with the data of day 0 with of day 70. Also, the values of vermicomposting coefficient were maximum for E. fetida. Moreover, the mean individual weight of E. fetida was also maximum during the decomposition period. Although Eu. eugeniae increased in total biomass much more rapidly than E. fetida, nevertheless, the cocoon production rate was greatest (78.67) in case of E. fetida, indicating the differential resource allocation with trade-off between sex alloca-tion and growth by Eu. eugeniae in a non-conducive environment during its life cycle. Overall, the results indicate suitability of E. fetida for vegetable waste degradation.

Wide Substrate Specificity

The alimentary tract of earthworm secretes a group of proteases with a relative wide substrate specificity. In 1983, six isozymes were isolated from earthworm with fibrinolytic activities and called fibriniolytic enzymes. So far, more isozymes have been found from different earthworm species such asLumbricus rubellusandEisenia fetida. For convenience, the proteases are named on the basis of the earthworm species and the protein function, for instance,Eisenia fetidaprotease (EfP). The proteases have the abilities not only to hydrolyze fibrin and other protein, but also activate proenzymes such as plasminogen and prothrombin. In the light of recent studies, eight of theEfPs contain oligosaccharides chains which are thought to support the enzyme structure. Interestingly,EfP-II has a broader substrate specificity presenting alkaline trypsin, chymotrypsin and elastase activities, butEfP-III-1 has a stricter specificity. The protein crystal structures show the characteristics in their specificities. Earthworm proteases have been applied in several areas such as clinical treatment of clotting diseases, anti-tumor study, environmental protection and nutritional production. The current clinical utilizations and some potential new applications of the earthworm protease will be discussed in this paper.
