| characterization and antioxidative activities of rare c₅₀ carotenoids-sarcinaxanthin, sarcinaxanthin monoglucoside, and sarcinaxanthin diglucoside-obtained from micrococcus yunnanensis. | while screening for antioxidative carotenoids from marine bacteria, we isolated and identified sarcinaxanthin and its glucosylated compounds (sarcinaxanthin monoglucoside and sarcinaxanthin diglucoside) from a moderately halophilic bacterium-micrococcus yunnanensis strain aoy-1. in the singlet oxygen ((¹o₂) quenching model, the ic₅₀ values of the antioxidative activities of these carotenoids were as follows: sarcinaxanthin , 57 µm; sarcinaxanthin monoglucoside, 54 µm; and sarcinaxanthin diglucos ... | 2010 | 21099143 |
| isolation, characterization, and use for plant growth promotion under salt stress, of acc deaminase-producing halotolerant bacteria derived from coastal soil. | in total, 140 halotolerant bacterial strains were isolated from both the soil of barren fields and the rhizosphere of six naturally growing halophytic plants in the vicinity of the yellow sea, near the city of incheon in the republic of korea. all of these strains were characterized for multiple plant growth promoting traits, such as the production of indole acetic acid (iaa), nitrogen fixation, phosphorus (p) and zinc (zn) solubilization, thiosulfate (s2o3) oxidation, the production of ammonia ... | 2010 | 21124065 |
| endophytic cultivable bacteria of the metal bioaccumulator spartina maritima improve plant growth but not metal uptake in polluted marshes soils. | endophytic bacterial population was isolated from spartina maritima tissues, a heavy metal bioaccumulator cordgrass growing in the estuaries of tinto, odiel, and piedras river (south west spain), one of the most polluted areas in the world. strains were identified and ability to tolerate salt and heavy metals along with plant growth promoting and enzymatic properties were analyzed. a high proportion of these bacteria were resistant toward one or several heavy metals and metalloids including as, ... | 2015 | 26733985 |
| potential of the essential oil from pimenta pseudocaryophyllus as an antimicrobial agent. | this study evaluated the effectiveness of the essential oil of pimenta pseudocaryophyllus in inhibiting the growth of the main bacteria responsible for bad perspiration odor (staphylococcus epidermidis, proteus hauseri, micrococcus yunnanensis and corynebacterium xerosis). the chemical profile of the essential oil was evaluated by high-resolution gas chromatography (hr-gc) and four constituents were identified, eugenol being the major component (88.6%). the antimicrobial activity was evaluated b ... | 2014 | 25296683 |
| description of micrococcus aloeverae sp. nov., an endophytic actinobacterium isolated from aloe vera. | a yellow gram-stain-positive, non-motile, non-endospore -forming, spherical endophytic actinobacterium, designated strain ae-6(t), was isolated from the inner fleshy leaf tissues of aloe barbadensis (aloe vera) collected from pune, maharashtra, india. strain ae-6(t) grew at high salt concentrations [10% (w/v) nacl], temperatures of 15-41 °c and a ph range of 5-12. it showed highest (99.7%) 16s rrna gene sequence similarity with micrococcus yunnanensis yim 65004(t) followed by micrococcus luteus ... | 2014 | 25048212 |
| paenibacillus yonginensis dcy84(t) induces changes in arabidopsis thaliana gene expression against aluminum, drought, and salt stress. | current agricultural production methods, for example the improper use of chemical fertilizers and pesticides, create many health and environmental problems. use of plant growth-promoting bacteria (pgpb) for agricultural benefits is increasing worldwide and also appears to be a trend for the future. there is possibility to develop microbial inoculants for use in agricultural biotechnology, based on these beneficial plant-microbe interactions. for this study, ten bacterial strains were isolated fr ... | 2015 | 25721473 |
| indoleacetic acid production and plant growth promoting potential of bacterial endophytes isolated from rice (oryza sativa l.) seeds. | bacterial endophytes from the phyllosphere and rhizosphere have been used to produce bioactive metabolites and to promote plant growth. however, little is known about the endophytes residing in seeds. this study aimed to isolate and identify seed-borne bacterial endophytes from rice and elucidate their potential for phytohormone production and growth enhancement. the isolated endophytes included micrococcus yunnanensis rwl-2, micrococcus luteus rwl-3, enterobacter soli rwl-4, leclercia adecarbox ... | 2017 | 28605980 |
| optimization of nutrients and culture conditions for alkaline protease production using two endophytic micrococci: micrococcus aloeverae and micrococcus yunnanensis. | an endophytic species of micrococcus was isolated from aloe vera leaf (syn. aloe barbadensis) and screened for protease production with five other species of micrococcus. data indicated that endophytic micrococcus aloeverae ae-6 mcc 2184(t) and micrococcus yunnanensis dsm 21948(t) showed efficient protease production potential and secreted active protease at high salt (10%), temperature (40 °c) and in wide range of ph 8-10. unlike m. yunnanensis dsm 21948(t), protease production by m. aloeverae ... | 2017 | 28611500 |
| effect of halotolerant rhizobacteria isolated from halophytes on the growth of sugar beet (beta vulgaris l.) under salt stress. | utilization of rhizobacteria that have associated with plant roots in harsh environments could be a feasible strategy to deal with limits to agricultural production caused by soil salinity. halophytes occur naturally in high-salt environments, and their roots may be associated with promising microbial candidates for promoting growth and salt tolerance in crops. this study aimed to isolate efficient halotolerant plant-growth-promoting rhizobacterial strains from halophytes and evaluate their acti ... | 2017 | 28460054 |
