“…One of the merR-like genes (Mlut_06140) is close to genes involved in mercury resistance (e.g., mercuric reductase, Mlut_06150), and another (Mlut_20770) is related to certain excisionases. At least four of the MerR/ArsR proteins are likely to play a role in metal resistance, which is of interest since M. luteus may have potential utility for gold recovery from low-grade ores (66,67).…”

Micrococcus luteus (NCTC2665, "Fleming strain") has one of the smallest genomes of free-living actinobacteria sequenced to date, comprising a single circular chromosome of 2,501,097 bp (G؉C content, 73%) predicted to encode 2,403 proteins. The genome shows extensive synteny with that of the closely related organism, Kocuria rhizophila, from which it was taxonomically separated relatively recently. Despite its small size, the genome harbors 73 insertion sequence (IS) elements, almost all of which are closely related to elements found in other actinobacteria. An IS element is inserted into the rrs gene of one of only two rrn operons found in M. luteus. The genome encodes only four sigma factors and 14 response regulators, a finding indicative of adaptation to a rather strict ecological niche (mammalian skin). The high sensitivity of M. luteus to ␤-lactam antibiotics may result from the presence of a reduced set of penicillin-binding proteins and the absence of a wblC gene, which plays an important role in the antibiotic resistance in other actinobacteria. Consistent with the restricted range of compounds it can use as a sole source of carbon for energy and growth, M. luteus has a minimal complement of genes concerned with carbohydrate transport and metabolism and its inability to utilize glucose as a sole carbon source may be due to the apparent absence of a gene encoding glucokinase. Uniquely among characterized bacteria, M. luteus appears to be able to metabolize glycogen only via trehalose and to make trehalose only via glycogen. It has very few genes associated with secondary metabolism. In contrast to most other actinobacteria, M. luteus encodes only one resuscitation-promoting factor (Rpf) required for emergence from dormancy, and its complement of other dormancy-related proteins is also much reduced. M. luteus is capable of long-chain alkene biosynthesis, which is of interest for advanced biofuel production; a three-gene cluster essential for this metabolism has been identified in the genome.Micrococcus luteus, the type species of the genus Micrococcus (family Micrococcaceae, order Actinomycetales) (117), is an obligate aerobe. Three biovars have been distinguished (138). Its simple, coccoid morphology delayed the recognition of its relationship to actinomycetes, which are typically morphologically more complex. In the currently accepted phylogenetic tree of the actinobacteria, Micrococcus clusters with Arthrobacter and Renibacterium. Some other coccoid actinobacteria originally also called Micrococcus, but reclassified into four new genera (Kocuria, Nesterenkonia, Kytococcus, and Dermacoccus), are more distant relatives (121). The genus Micrococcus now includes only five species: M. luteus, M. lylae, M. antarcticus, M. endophyticus, and M. flavus (20, 69, 70, 121).We report here the genome sequence of Micrococcus luteus NCTC2665 (DSM 20030 T ), a strain of historical interest, since Fleming used it to demonstrate bacteriolytic activity (due to lysozyme) in a variety of body tissues and secretions (29,3...

“…So far, such processes proceeding in mild conditions have been unknown though complexes with Au H-C agostic interactions are were described [79]. The first indication of catalytic activity of gold in mild conditions (aqueous solution, room temperature) was detection of methane oxidation by oxygen in the presence of specific gold containing NADH oxidase of Micrococcus luteus [80]. Gold containing bacteria use 4 as an alternative source of energy at the lack of easier oxidizing organic substrates.…”

Synthesis, Spectral and Antioxidant Properties of Tin(II)-Rutin Complex

Rutin is one of the most common flavonoids present in nature that has a wide range of biological properties. A Tin(II)-rutin complex was synthesized from the raw material rutin and SnCl 2 in an alkaline solution. The complex was characterized by UV-vis, IR, 1 H NMR, and 13 C NMR spectroscopy. We evaluated the free radical scavenging activity using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method, and the results showed that pure rutin was more effective than the Tin(II)-rutin complex in terms of antioxidant activity. Supplementing diet by foods rich in rutin and other flavonoids, such as vegetables and fruits, may contribute to removing free radicals and heavy metal ions in our body.Tinplate, commonly known as tin-plated steel sheet, is a kind of cold-rolled low-carbon steel sheet coated with pure tin on both sides. This material combines the durable strength of steel with the corrosion resistance of tin in one. These characteristics are the reasons why tinplate is widely used in the manufacture of rigid containers, especially for food and beverage packaging. Normally the concentration of tin in the majority of foods should be less than 1 part per million (ppm); however, in canned foods, especially those with an acidic pH, noticeably higher levels or more may be found [e.g., 100-500 ppm (0.01-0.05%)]. Regular consumption of these foods will cause symptoms of tin poisoning, such as vomiting, diarrhea, and anorexia [1].Chelation therapy is the preferred method for reducing the heavy metal induced toxicity. Chelating agents tightly bind to toxic metal ions to form complex structures that are easily excreted from the body [2]. Flavonoids are polyphenolic natural products widely distributed in plant foods, with a wide range of biological activities and pharmacological properties such as cardiovascular protection, anti-cancer, anti-ulcer, anti-oxidation, anti-viral, and anti-inflammatory; in addition, flavonoids are also natural antioxidants, free radical scavengers, and metal chelators [3]. Rutin is one of the most common flavonoids present in nature that has a wide range of biological properties, such as anti-inflammatory [4], anticancer [5], antioxidant [6], and so on. Rutin is an effective metal chelator [7, 8]. The complexation of metal cations by rutin has already been reported for a large number of metals: Zn (II), Al (III) [9], Cu (II) [10], Co (II) [11], Fe (II) [12], Fe (III) [13], Mn (II) [14], V (II) [15], U (II) [16], and Au (III) [17]. Rutin has attracted the attention of many researchers because of these special properties [18]. Supplementing regular diet with foods rich in rutin and other flavonoids, such as ginkgo biloba and buckwheat, may contribute to removing free radicals and heavy metal ions in our body [19,20].The purpose of this investigation was to study the chelating properties of rutin with tin cations [Sn(II)] and investigate the variation in antioxidant properties of rutin after chelation.The UV-vis spectrum of free rutin and Tin(II)-rutin complex in MeOH is reported in Fig. 1. Rutin exhibit...
