SEBUAH temuan mutakhir dihasilkan pakar mikrobiologi pertanian Unud, Dr. Ir. Ni Luh Kartini, M.S. Cacing tanah bagi Kartini bukan cuma berkhasiat menyuburkan tanaman. Perempuan Bali asal Kubutambahan, Buleleng, ini memastikan cacing tanah mampu mengenyahkan keluhan sejumlah jenis penyakit manusia.

Jakarta, Kamis. Cacing tanah di dunia telah teridentifikasi sebanyak 1.800 spesies. Dari jumlah tersebut, ada dua spesies, yaitu Lumbricus rubellus (dikenal dengan cacing eropa atau introduksi) dan Pheretima aspergillum (dikenal dengan nama cacing kalung atau di long), yang banyak digunakan dalam pengobatan tradisional. L. rubellus telah banyak dibudidayakan di Indonesia, sedangkan Ph. aspergillum belum banyak dibudidayakan.

Humic acids (HA) extracted from sheep (SHHA), cow (COHA), goat (GOHA) and rabbit (RAHA) vermicomposted manure were analyzed by electron paramagnetic resonance and hydrogen nuclear magnetic resonance spectroscopies. Carboxylic acids, amine, amide, ester, ether and phenol functions bonded to saturated aliphatic, unsaturated aliphatic conjugated double and single bonds, and aromatic chains constitute the backbone structure of these fresh humic substances (HS).

Humic acids (HA) were extracted from sheep (SH), cow (CO), goat (GO) and rabbit (RA) manures which were vermicomposted with the earthworm Eisenia foetida. HA DSC curves showed well-defined thermal events indicative of intramolecular bonds (300 oC) and intermolecular organomineral linkages (500 oC). All samples showed high nitrogen contents (from peptide chains and probably N-heterocycles) and aromatic and/or unsaturated aliphatic conjugated structures, as well as a low carboxylic functionality content.

Earthworms can be used to treat solid organic waste. Many studies have reported the effect of temperature, moisture, and pH value on the growth, reproduction, and survival of earthworms in manure. A study of the influence of these parameters on the growth and survival of earthworms in municipal solid waste is presented in this paper.

Twenty four study areas of three most widespread soil types (pebble rendzinas, typical brown soils and pseudopodzolic soils) all over Estonia were selected. In each group of soil type, eight fields were selected for studies in 2003–2004. The mean abundance of earthworm communities was the highest in pseudopodzolic soils (107.11±22.4 individuals per m2) and lower in pebble rendzinas (47.94±11.25 individuals per m2) and typical brown soils (72.97±15.13 individuals per m2).

This research illustrates the qualitative and quantitative composition of the mycoflora of both a green compost (thermophilically produced from plant debris) and a vermicompost (mesophilically produced by the action of earthworms on plant and animal wastes after thermophilic preconditioning). Fungi were isolated using three media (PDA, CMC, PDA plus cycloheximide), incubated at three temperatures (24, 37 and 45 C). Substantial qualiquantitative differences in the species composition of the two composts were observed.

The impact of fertilization on the yield, culinary properties and processing quality of potatoes was studied in a field experiment carried out during 1994-1996. Early cultivars Voke and Nida and late cultivar Vilnia were grown at the Experimental Station of the Lithuanian Agricultural University.

G-90 is a glycolipoprotein mixture obtained from the tissue homogenate of earthworm Eisenia foetida (Annelida, Lumbricidae) which exhibits pleiotropic biological functions. The antibacterial activity of G-90 was investigated in vitro and in vivo. Concentrations of 10 ng/mL and 10 μg/mL of G-90 exhibited an inhibitory effect on in vitro growth of non-pathogenic and facultative-pathogenic bacteria.

 In the present study, Northern part of Iran as chosen as study area. Four hunched samples of earthworms were collected by three methods (hand-sorting, chemical and heat extraction) of which 352 and 20 were mature and immature earthworms, respectively from different parts of the area. Following the method introduced by Graff the earthworms were placed in formaldehyde (5 and10%) and ethyl alcohol (60%).
