Crystal structures of 1, 2, 4, 9, 12, 13, 15, and 16 established the stereoretentive nature of the transformation processes. Though the complexes of L1, L3, and L 4 were isolated in the isomeric form A (π-acceptor trpy and azole ring in the equatorial plane and the pyridine and chloride donors in the axial positions), complexes of L 2 preferentially stabilized in form B (trpy and pyridine in the equatorial plane and the azole ring and chloride donors in the axial positions). The v(NO) stretching frequency varied in the range of 1957-1932 cm(-1), 13 &amp;MGT; 14 &amp;MGT; 15 &gt; 16, primarily depending on the electronic aspects of L as well as the isomeric structural forms. The coordinated nitrosyl function underwent successive reductions of [Ru-II-NO+](3+) &amp;RARR; [Ru-II-NO&amp;BULL;](2+) and [Ru-II-NO&amp;BULL;](2+) - [Ru-II-NO-](+), and the first reduction potential follows the order 14 &gt; 13 &amp;MGT; 15 &amp;AP; 16. The nearly axial EPR spectra having nitrogen hyperfine splittings (A &amp;AP; 26 G) at 77 K of 13(-)-16(-) with (g) &amp;AP; 2.0 established that the reduction process is largely centered around the nitrosyl function. Despite an appreciably high v(NO), the complexes were found to be unusually stable even in the aqueous medium. They transformed slowly and only partially into the corresponding nitro derivatives in H2O (k &amp;AP; 10(-4) s(-1) and K = 0.4-3.8). The chloro (1-4), aqua (5-8), and nitro (9-12) derivatives displayed reasonably strong emissions near 700 nm at 77 K (φ = 10(-1)-10(-2)). The aqua derivative 7 was found to interact with the calf thymus and the circular form of p-Bluescript SK DNA.</p>1 aChanda, N.1 aPaul, D.1 aKar, S.1 aMobin, Shaikh, M.1 aDatta, Anindya1 aPuranik, Vedavati, G.1 aRao, K., K.1 aLahiri, Goutam, Kumar  uhttps://library.ncl.res.in/content/effect-2-2-pyridylazole-based-ancillary-ligands-l1-4-electrophilicity-nitrosyl-function-ru-101589nas a2200181   4500008004100000245010900041210006900150260004600219520091300265100001901178700001301197700001501210700001701225700001501242700001401257700001401271856012201285       2016                        eng d00aDiversity of arsenic resistant bacteria from Lonar lake: A meteorite impact alkaline crater lake in Indi0 aDiversity of arsenic resistant bacteria from Lonar lake A meteor  aStockholm; SwedenbCRC Press/BalkemacJUN3 aLonar lake known for its meteorite impact origin and highly alkaline environment harbors a plethora of diverse organisms. Arsenic transforming microbe diversity from Lonar remains unexplored. We attempted to explore the microorganisms causing arsenic transformation using culture-dependent and independent approaches. Amongst the 67 microbes isolated, Bacillus infantis L4-18 and Bacillus solimangrovi L4-7b could oxidise 15 mM arsenite in 8 days. None of the cultures could reduce arsenate. All the other isolates resisted 2 mM arsenic. In the culture independent approach, microbial diversity revealed Bacteroides (41.9%), followed by Proteobacteria (17.9%), Firmicutes (14.2%), Actinobacteria (13.9%), occurring in the Lonar sediment sample. This study provides foundation to study microbial arsenic biogeochemical cycle along with other biochemical cycles and microbial function in Lonar lake eco system.1 aBagade, A., V.1 aPaul, D.1 aRikame, T.1 aGiri, A., P.1 aDhotre, D.1 aPawar, S.1 aKodam, K.  uhttps://www.scopus.com/record/display.uri?eid=2-s2.0-85017026744&origin=inward&txGid=63266bcb17f730d2678898ea486dffa602060nas a2200253   4500008004100000022001400041245016900055210006900224260000800293300001400301490000700315520121400322653001601536653001201552653001201564653001701576653001001593100001401603700001401617700001401631700001301645700001701658856013101675       2022                        eng d  a0266-825400aScreening of osmotic stress-tolerant bacteria for plant growth promotion in wheat (Triticum aestivum L.) and brinjal (Solanum melongena L.) under drought conditions0 aScreening of osmotic stresstolerant bacteria for plant growth pr  cNOV  a1286-12920 v753 a<p>
	Drought stress adversely affects plant growth and productivity. Therefore, the application of plant growth-promoting bacteria is a viable option for combating drought resistance in crops. In this study, 144 bacteria were isolated from the Kutch desert soil in Gujarat. Based on osmotic stress tolerance and PGP properties, two strains, Bacillus tequilensis (KS5B) and Pseudomonas stutzeri (KS5C) were tested for their effect on wheat (Triticum aestivum L.) and brinjal (Solanum melongena L.) under drought stress conditions. Inoculation with osmotic stress-tolerant bacteria showed 15 center dot 15-29 center dot 27% enhancement in root length of wheat and 15 center dot 27-32 center dot 59% in brinjal plants. Similarly, the enhancement of shoot length ranged from 14 center dot 72 to 37 center dot 70% for wheat and 59 center dot 39-95 center dot 94% for brinjal plants. Furthermore, the inoculated plants showed significant improvement in chlorophyll content and antioxidant properties such as proline, peroxidase and polyphenol oxidase activity compared to the control. Therefore, the bacterial strains identified in this study can be used to mitigate drought stress and enhance plant biomass.</p>
