From Piriformospora indica to Rootonic: A review
Piriformospora indica (Hymenomycetes, Basidiomycota) is a cultivable endophyte that colonizes roots and has been extensively studied. P. indica has multifunctional activities like plant growth promoter, biofertilizer, immune-modulator, bioherbicide, phytoremediator, etc. Growth promotional characteristics of P. indica have been studied in enormous number of plants and majority of them have shown highly significant...

Effects of cultivating orchid Gastrodia elata with the introduced Armillaria in a local ecosystem
To characterize the potential effects of an introduced fungus in a local ecosystem, an experiment was performed in an abandoned farmland, where a traditional Chinese medicinal plant, Gastrodia elata had been continuously cultivated using the introduced Armillaria M2 and it had not been grown for the last 6 years. In this case, a newly introduced Armillaria strain M1 was used to cultivate orchid G. elata again....

Antimicrobial activity of fungi isolated from the water of the sky high, Recife-PE supply against bacteria of clinical interest system
Water supply assumes an important role, since it can serve as a vehicle for microorganisms such as viruses, bacteria and pathogenic fungi. The presence of a group of microorganisms (fungi) that cause deterioration of water quality is related to the production of secondary metabolites, such as antibiotics and toxins. One of the reasons of carrying out tests with these organisms is, among other things, to verify their...

Activity of the desert truffle Terfezia boudieri Chatin, against associated soil microflora
This research focuses on the activity of the desert truffle Terfezia boudieri Chatin against its associated microflora. It consists of the enumeration and pre-identification of soil microflora associated with ascocarps of T. boudieri Chatin, in contact with fungus ascocarps and at 10 cm deep. Enumeration reveals that the number of some microorganisms is higher when in contact with ascocarps of T. boudieri than at 10 cm...

Bovine vaginal lactobacilli and their adherence to mucus in different phases of the estrous cycle
The aim of the study was to isolate vaginal latobacilli from heifers and cows with healthy reproductive tract and to test their adherence to vaginal mucus in different phases of the estrous cycle. Moreover, the strains were tested to produce hydrogen peroxide and organic acids and in vitro antagonistic activity against pathogenic indicator strains. Five strains were selected (from 244 samples of 122 heifers and cows)....

Effect of resource conservation practices and conventional practices on population dynamics of Meloidogyne graminicola (Golden and Birchfield, 1965) under rice-wheat cropping system
Study on effect of resource conservation practices and conventional practices on population dynamics of Meloidogyne graminicola under rice-wheat cropping system revealed that the fields with the intervention of resource conservation practices showed high population densities, root knot index and narrow nematode to root biomass ratio of M. graminicola as compared to conventional ones. It was also found that those tillage...

Yeasts in traditional Moroccan goat cheese
Nine samples of goat’s cheese were collected. A total of 68 yeasts were isolated and grouped according to their M13 PCR-fingerprints. Representative isolates of each fingerprint group were identified using rRNA and/or protein-coding gene sequencing leading to the identification of 18 yeast species. The dominant species were Kluyveromyces lactis (19.1%), Saccharomyces cerevisiae (11.7%), Yarrowia lipolytica...

Establishing cause effect of multistressor environments on Oreochromis niloticus and its parasite communities
This study investigated the composition and structure of the parasitic communities in Oreochromis niloticus with respect to levels of water quality in three different ecosystems. A total of 366 O. niloticus were examined from three water courses: CLAR ponds, (unpolluted), Abbassa privet ponds (slightly polluted) and Manzalla ponds (polluted). Trematodes, monogeneans, cestodes and acanthocephalans were found in all the...

Isolation and identification of secondary metabolites producer Nocardia spp. from Iraqi soil
One hundred and sixty nine Nocardia isolates were recovered from 111 Iraqi soil samples on six cultivation media, using paraffin baiting and dilution techniques. The North of Iraq soil was the richest in Nocardia. Paraffin baiting technique was more efficient in the isolation of Nocardia than dilution technique. Glucose asparagine agar was more suitable for cultivating Nocardia isolates followed by Sabouraud dextrose...

Incidence of kernel smut caused by Tilletia barclayana in Egyptian rice cultivars
The study was conducted to determine the effects of cultivars susceptibility to infection with the pathogenic isolates on the pathogenicity of rice kernel smut fungus (Tilletia barclayana). Rice (Oryza sativa L.) cultivars vary in susceptibility to kernel smut disease. The susceptibility of 18 commercial rice cultivars to T. barclayana was evaluated. Moreover, pathogenicity of 46 isolates of T. barclayana which had been...
