Diversity of microflora in the gut and casts of tropical composting earthworms reared on different substrates.
The diversity of fungi, bacteria, yeast, actinomycetes and protozoa were analysed in the gut and casts of Eudrilus eugeniae, Lampito mauritii, Eisenia fetida and Perionyx excavatus, both qualitatively and quantitatively as influenced by different feed substrates like clay loam soil, cowdung and pressmud. While actinomycetes (Streptomyces albus, S. somaliensis, Nocardia asteroides, N. caviae and...
متن کاملLactic acid microflora of the gut of snail Cornu aspersum
The intestinal lactic acid microflora of the edible snail Cornu aspersum was studied by culture-based methods and was phenotypically and molecularly characterized. The antibacterial activity of lactic acid bacteria (LAB) isolates was investigated. Snails in different stages of development were collected from farms located in several regions of Bulgaria. One hundred twenty-two isolates, belongin...
متن کاملLactic Acid Microflora of Bulgarian Milk Products from Mountain Regions
This study aimed to isolate and characterize viable lactic acid bacteria (LAB) from the most popular in Bulgaria fermented milk products. Different samples from home-made cheeses, yoghurt and katak, from ecological regions of Stara Planina, Rila and Rodopi mountains were collected. A total of 25 LAB cultures (coci and rods) were isolated and polyphasic taxonomic characterization was performed. ...
متن کاملEarthworms and Soil Pollutants
Although the toxicity of metal contaminated soils has been assessed with various bioassays, more information is needed about the biochemical responses, which may help to elucidate the mechanisms involved in metal toxicity. We previously reported that the earthworm, Eisenia fetida, accumulates cadmium in its seminal vesicles. The bio-accumulative ability of earthworms is well known, and thus the...
متن کاملCorrosion Behavior of Titanium in Artificial Saliva by Lactic Acid
As one of the main products produced by oral microorganisms, the role of lactic acid in the corrosion of titanium is very important. In this study, the corrosion behavior of titanium in artificial saliva with and without lactic acid were investigated by open-circuit potentials (OCPs), polarization curves and electrochemical impedance spectroscopy (EIS). OCP firstly increased with the amount of ...
