introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...

A pot experiment was carried out during 2009 and 2010 to study the field performance of blue pine seedlings inoculated with selected species of bio-inoculants under nursery conditions .The experiment was laid in Completely Randomized Design with three replications which comprised of seven inoculants (Azotobacter sp., Azospirillum sp., Pseudomonas fluorescens, Bacillus subtilis, Pisolithus tinct...

statement of problem: the guided bone regeneration (gbr) technique does not always produce consistent results. bone filling within the space provided by the membrane can be incomplete. purpose: the aim of this study was to evaluate the effect of a collagen membrane (bio-gide) in combination with or without deproteinezed bovine bone mineral (bio-oss) on the healing of calvarial defects in rabbit...

Bacteria isolated from extreme environments have been shown to promote plant growth under challenging conditions. This study aimed examine the performance of extremophilic microorganisms salt stress and their ability improve tolerance soybean plants this stress. In vitro experiments showed that bacteria belonging genera Stenotrophomonas Exiguobacterium were halophilic displayed growth-promoting...

abstractbackground and objectives: the cultivated tobacco (nicotiana tabacum) is a tropical and annual plant, consisting of a number of species or hybrids belonging to the solanaceae family. bio-chemical reaction to viral infection is different for various plants .one of the most important defensive mechanisms of the host plant against pathogen agents, is biochemical defense and their related c...

We compared the performances of various DNA extraction kits for their ability to recover Brucella abortus strain 19 inoculated into Brucella-free bovine tissues. Tissues were homogenized in a FastPrep bead homogenizer and extracted in triplicate by using one of five kits (Qiagen DNeasy, GE Illustra, Omega Bio-tek E.Z.N.A., Quanta Extracta, and IBI Science DNA Tissue kit). Whole blood was also t...

Methods The study was conducted in SICU. ASCs were performed from 20 Sep 10 to 28 Feb 11 on all patients admitted/ transferred in/transferred out of SICU. ASC specimens consisted of swabs from anterior nares and axilla/groin. The swabs were inoculated onto chromogenic agar selective for MRSA (MRSASelect, Bio-Rad). MRSA positive patients were placed on contact precautions/isolation. Automatic ha...

Fennel fruits (Foeniculum vulgare Mill.) represent one of the plant-based natural spices. This study aims to improve fruit yield and essential oil (EO) quality by reducing undesirable component, estragole, under different fertilizer treatments. The fertilizers included chemical nitrogen, phosphorus, potassium (NPK), also organic additive, rabbit manure (RM). For bio-fertilization, plants were i...

The bio-chemical changes which occur in fish tissues are due to two factors, autolysis and bacterial action. As early as 1903, Muller reported that changes due to autolysis took place when sterile fish tissues were incubated. More recently attention has been focussed on the relative importance of these two causes of bio-chemical change. Reed, Rice and Sinclair (1929) presented evidence that aut...

rose flower (rosa hybrida) is appreciated for its beauty, fragrance and long period of flowering. to study the response of cut rose flower to bio-fertilizers, a factorial experiment was performed, with completely randomized design and four replications, in hydroponic greenhouse of alandasht, astane ghods garden, mashhad, iran, during 2009-2010. the first factor was six cultivars of rose flower ...
