Four treatments, a T1 control (soil without biochar), T2 alone, T3 T4 together, arranged randomized complete block design with five replications. alone had...

Treatment of the oily produced water (OPW) before injection into oil reservoirs is necessary to reduce formation damage. This can be done using chemo-physical process minimize droplets in water. In this respect, work aims extract natural polymer (chitosan) from shrimp shells and mix it with coagulants (chitosan/carboxy methyl cellulose chitosan/aluminum sulfate) adsorb OPW. Adsorption experiments were carried out batch mode firstly choose best treatment, also investigate effects pH on...

Abstract Oleaginous yeasts are considered promising sources for lipid production due to their ability accumulate high levels of lipids under appropriate growth conditions. The current study aimed isolate and identify oleaginous having superior quantities lipids; enhancing using response surface methodology repeated-batch fermentation. Results revealed that, twenty marine were isolated, the most potent producer was Candida parapsilosis Y19 according qualitative screening test Nile-red dye....

Crude oil is the most critical energy source in world, especially for transportation, provision of heat and light as there has not been a sufficient to replace crude broadly integrated, so an urgent need maximize extraction original in-place every reservoir, accelerating development enhanced recovery (EOR) technologies. Polymer flooding by hydrophobically associated polyacrylamides (HAPAM) widely used technique through EOR technology. For successful application these polymers, one should...

Crude oil and other petroleum products are crucial to the global economy today due increasing energy demand approximately (∼1.5%) per year significant remaining after primary secondary recovery (∼45–55% of original in place, OOIP), which accelerates development enhanced (EOR) technologies maximize recovered amount by non-conventional methods as polymer flooding. This review discusses specially flooding techniques their effects on rock wettability alteration.

In this work, polymer molecules of alkene oxides diesters with varying HLB values and molecular weights (ED1, ED2, ED3, PD1, PD2 PD3) were synthesized, elsewhere (Alsabagh et al., 2016). The demulsification efficiency was evaluated at field reservoir conditions. At conditions (60 °C 1 atm) the data revealed that maximum obtained by ED3 PD3 60 °C, 600 ppm after 55 40 min, respectively. (85 5000 psi), showed also 76% 70%, respectively, in spite 2% from blank emulsion (12% BS&W) separated 7...

Arbuscular mycorrhizal fungi (AMF) inoculation and biochar amendment has been reported to improve the growth of several crop plant; however, their role in stress amelioration individually as well combination not worked out. Limited information is available about synergistic use Mycorrhizal Fungi (AMF). Here, we investigated effect AMF on plant development, root architecture, physiological performance fenugreek (Trigonella foenum-graecum), soil enzymatic activities. Biochar were shown have a...

Co-inoculation with beneficial microbes has been suggested as a useful practice for the enhancement of plant growth, nutrient uptake, and soil nutrients. For first time in Uzbekistan role plant-growth-promoting Bacillus endophyticus IGPEB 33 arbuscular mycorrhizal fungi (AMF) on physiological properties ginger (Zingiber officinale), enzymatic activities was studied. Moreover, coinoculation B. AMF treatment significantly increased height by 81%, leaf number 70%, length 82%, width 40% compared...

Anti-virulence agents are non-bacteriostatic and non-bactericidal emerging therapeutic options which hamper the production of virulence factors in pathogenic flora. In Staphylococcus aureus Enterococcus faecalis, regulation genes' expression occurs through cyclic peptide-mediated accessory gene regulator (agr) its ortholog fsr quorum sensing systems, respectively. present study, we screened a set 54 actinomycetales secondary metabolites as novel anti-virulence compounds targeting system...

Conventional agriculture plays a vital role in meeting the increasing demands for food which result from continuous rising of human population. Nowadays farmers use more and amounts chemical fertilizers pesticides have bad influence on soil quality, ecosystem, health humans. Hence, it is important to explore other approaches decrease application enhance crop productivity. Inoculation with plant growth promoting rhizobacteria (PGPR) augment sustainable production another strategy that...

Cyclic peptides are commonly used as quorum-sensing autoinducers in Gram-positive Firmicutes bacteria. Well-studied examples of such molecules thiolactone and lactone, to regulate the expression a series virulence genes agr system Staphylococcus aureus fsr Enterococcus faecalis, respectively. Three cyclodepsipeptides WS9326A, WS9326B cochinmicin II/III were identified result screening actinomycetes culture extracts for activity against agr/fsr system. These already known receptor...

Ginger is rich in different chemical compounds such as phenolic compounds, terpenes, polysaccharides, lipids, organic acids, minerals, and vitamins. The present study investigated the effect of mineral fertilizers on content elements rhizomes Zingiber officinale Roscoe, soil enzymes activity, properties Surkhandarya Region, Uzbekistan. To best our knowledge, first Uzbekistan to investigate ginger rhizome inhabiting Termez district, region. A Field experiment was conducted at experimental...

Quorum sensing inhibitor (QSI) has been attracting attention as anti-virulence agent which disarms pathogens of their virulence rather than killing them. QSI marking cyclic peptide-mediated QS in Gram-positive bacteria is an effective tool to overcome the crisis antibiotic-dependent chemotherapy due emergence drug resistance strain, e.g., methicillin resistant Staphylococcus aureus (MRSA) and Vancomycin Enterococci (VRE). From a semi-large-scale screening thus far carried out, two Epoxide...
