Seven Bacillus spp. isolated from the marine water and rhizosphere of medicinal plant Coscinium fenestratum were studied to produce growth promotion (PGP) traits invitro. Among seven isolates, MMRH22 RHPR20 produced copious amounts PGP traits. Based on 16S rRNA sequence, two potent bacterial MMRH22, identified as mojavensis cereus, respectively. A compatibility test between isolates revealed th...

BACKGROUND Cucurbitacins are mostly found in the members of the family Cucurbitaceae and are responsible for the bitter taste of cucumber. Pharmacological activities such as anti-bacterial and anti-tumor effects have been attributed to these structurally divers triterpens. The aim of this study was to investigate the effect of potassium phosphite (KPhi) and chitosan on Cucurbitacin E (CuE) conc...

The use of antibiotics in the treatment livestock has increased productivity meat and dairy industry. flip side effectiveness drugs this group is presence effects, which have caused concern about widespread cause need to control residual content antibacterial agents products. From soil samples collected 7 regions Kazakhstan, 14 microbial isolates were isolated identified as B. licheniformis, so...

We analyzed epicuticular hydrocarbon variation in geographically isolated populations of D. mojavensis cultured on different rearing substrates and a sibling species, D. arizonae, with ultraviolet laser desorption/ionization mass spectrometry (UV-LDI MS). Different body parts, i.e. legs, proboscis, and abdomens, of both species showed qualitatively similar hydrocarbon profiles consisting mainly...

The desert fruit fly Drosophila mojavensis experiences environmental conditions of high temperature and low humidity. To understand the physiological mechanisms allowing these small insects to survive in such stressful conditions, we studied the effects of thermal acclimation on cuticular lipids and rates of water loss of adult D. mojavensis. Mean hydrocarbon chain length increased at higher te...

Understanding the genetic basis of adaptation to novel environments remains one of the major challenges confronting evolutionary biologists. While newly developed genomic approaches hold considerable promise for addressing this overall question, the relevant tools have not often been available in the most ecologically interesting organisms. Our study organism, Drosophila mojavensis, is a cactop...

Noble metallic nanostructures with strong electric near-field enhancement can significantly improve nanoscale light–matter interactions and are critical for high-sensitivity surface-enhanced Raman spectroscopy (SERS). Here, we use an azimuthal vector beam (AVB) to illuminate the plasmonic tips circular cluster (PTCC) array enhance intensity of PTCC array, then it SERS sensitivity. The was prepa...
