The major agro-industrial effluents of sugarcane and starch industries pose a serious threat to surface waters. Their disposal in the River Nile around Cairo city transitionally affected microbial load. In situ bacterial enrichment (50–180%) was reported gradually diminished downstream; lateral not vertical effect effluent evident. Disposed increased BOD COD, then progressively decreased downstream. Ammoniacal N elevated, indicating active biological ammonification biodegradability...
Our previous publications and the data presented here provide evidences on ability of plant-based culture media to optimize cultivability rhizobacteria support their recovery from plant-soil environments. Compared tested chemically-synthetic (e.g. nutrient agar N-deficient combined-carbon sources media), slurry homogenates, crude saps, juices powders cactus (Opuntia ficus-indica) succulent plants (Aloe vera Aloe arborescens) were rich enough growth rhizobacteria. Representative isolates...
North Sinai deserts were surveyed for the predominant plant cover and culturable bacteria nesting their roots shoots. Among 43 species reported, 13 are perennial (e.g. Fagonia spp., Pancratium spp.) 30 annuals Bromus Erodium spp.). Eleven possessed rhizo-sheath, e.g. Cyperus capitatus, Panicum turgidum Trisetaria koelerioides. Microbiological analyses demonstrated: great diversity richness of associated bacteria, in particular nitrogen-fixing (diazotrophs); majority bacterial residents true...

In order to improve the culturability and biomass production of rhizobacteria, we previously introduced plant-only-based culture media. We herein attempted widen scope plant materials suitable for preparation chemically analyzed refuse turfgrass, cactus, clover. They were sufficiently rich support good in vitro growth by rhizobacteria isolates representing Proteobacteria Firmicutes. also adequate efficient produce a cell liquid batch cultures.

Abstract This study evaluates the efficacy of discrete bacterial consortia in bioremediating sandy loamy soil deliberately contaminated with 20 mg/kg chlorantraniliprole (CAP). It monitors alterations total populations and CO 2 emissions, tracking residual CAP levels through UV scanning HPLC analysis. Six active degraders (four Bacillus strains ( B. subtilis subsp .

The exclusive use of plant juices, not as a mere supplement to synthetic culture media, for culturing rhizospheric microorganisms (RMO) is introduced here. Juices were prepared from desert (Mesembryanthemum crystallinum L., Zygophyllum album Carpobrotus edulis L.) well cultivated (Trifolium alexandrinum Beta vulgaris plants. Colonies RMO (Azospirillum brasilense, Enterobacter agglomerans and Klebsiella pneumoniae) nicely developed on surface-inoculated agar plates crude diluted juice M. (ice...
We have developed teabags packed with dehydrated plant powders, without any supplements, for preparation of infusions necessary to develop media culturing rhizobacteria. These bacteria are efficiently cultivated on such teabag culture media, better progressive in situ recoverability compared standard chemically synthetic media. Combining various plant-based and incubation conditions enabled us resolve unique denaturing gradient gel electrophoresis (DGGE) bands that were not resolved by...

Abstract The mass spectra of ten dehydration and solvolysis products obtained from β‐amyrin glycyrrhetic acid were studied. With the exception those resulting ‘backbone’ rearrangement, they exhibited conventional fragmentation due to ring C chromophore, like parent alcohols. Only with a contracted A suffered loss an isopropyl radical. In latter type, special features by isopropylcyclopentene isopropylidene products. These differences enabled assignment probable structures for two unknown derivatives.
