[8]. B. paper highlights characteristics of a group of 5 Gram-positive nonmotile coccoid bacteria identified as belonging to the genera Micrococcus and Planococcus. A novel aerobic, Gram-stain-positive, motile, moderately halophilic and coccoid bacterial strain, designated LCB217 T, was isolated from a saline-alkali soil in north-western China and identified using a polyphasic taxonomic approach.Growth occurred with 3-15 % (w/v) NaCl (optimum 3-5 %), at 10-45 °C (optimum 30 °C) and at pH 7.0-9.0 (optimum pH 9.0). Bacteria of this genus are of primary clinical significance. INTRODUCTION. SWANNELL AND I.M. Methylobacterium is a facultative methylotroph, (meaning it has the ability to grow by reducing carbon compounds with one or more carbon atoms but no carbon-carbon bonds (Chistoserdova et al.2003)), that grows on methylamine, methanol, and C 2, C 3, and C 4 compounds, including the methanol emitted by the stomata of plants. The results of animal research indicate that the probiotic benefits of Enterococcus faecium include boosted immune cell function, improved regulation of cell proliferation, and elevated fat … Abstract. There, S. aureus appears as yellow-pigmented colonies that show areas of partial hemolysis around them. Morphology: Spherical cocci; often forming regular and "grape-like" clusters. They are normal Meanwhile, most of the Planococcus bacteria have showed the ability to withstand heavy metals, produce surfactants and adapt to cold and/or saline environments [12–14]. Description and Significance. A Gram stain is a lab test used to detect bacteria or fungi in a sample taken from the site of a suspected infection. S. aureus appears in gram-staining as blue grape-like clusters of spherical bacteria. are gram-positive (+) bacteria in the family of Planococcaceae (Bacillales, Firmicutes). (thefreedictionary.com)A facultative alkaliphilic protease-producing gram-positive rod-shaped bacteria (EMGA 5) was isolated from mangrove soil and confirmed as Bacillus flexus by the 16S rDNA sequence. Gram Stain: Positive. Description: Micrococcus luteus (M. luteus) is a Gram-positive to Gram-variable, non-motile, coccus, saprotrophic bacterium. So far, we have not isolated Klebseilla from MSA. The Gram stain is a differential staining technique used to classify & categorize bacteria into two major groups: Gram positive and Gram negative, based on the differences of the chemical and physical properties of the cell wall. MSA is supposed to inhibit gram negative bacilli. • Gram-negative, rods, non-spore forming, facultative anaerobic bacteria. ENGELHARDT, K. DALY, R.P.J. 2001.

Many authors continued to place motile cocci in the genus Micrococcus, arguing that motility was not sufficient grounds to place the organisms in a completely different genus.However, it was demonstrated subsequently that the mol% G + C content … coccus-shaped colony-forming Planococcaceae, a family within the order Bacillales, embraces 14 genera: Bhargavaea, Caryophanon, Chryseomicrobium, Filibacter, Jeotgalibacillus, Kurthia, Paenisporosarcina, Planococcus, Planomicrobium, Rummeliibacillus, Solibacillus, Sporosarcina, Ureibacillus, and Viridibacillus.Members of the family are Gram-variable, spore forming or nonspore forming, and motile … 6. Probiotic bacteria protect these sites by taking up position and establishing a protective barrier in the gut. capable of causing human disease) No = 0, Yes = 1: Plant pathogen: Does the species causes disease in plants? Gregersen T (1978) Rapid method for distinction of Gram-negative from Gram-positive bacteria. HEAD. False. ; M. luteus was first known as Micrococcus lysodeikticus and was discovered by Alexander Fleming in 1928. They occur singly, in pairs, tetrads, and short chains. Micrococci are microbiologically characterized as gram-positive cocci, 0.5 to 3.5 μm (micrometres; 1 μm = 10-6 metre) in diameter. Strain NEAU-ST10-9(T) is a moderately halophilic, coccoid and non-motile bacterium isolated from saline and alkaline soils in the Dechang Township, Zhaodong City, China. May cause opportunistic infection in an immunocompromised host. can diagnosis on … Eur J Appl Microbiol Biotechnol 5:123–127. Planococcus citri, commonly known as the citrus mealybug, is a species of mealybugs native to Asia.It has been introduced to the rest of the world, including Europe, the Americas, and Oceania, as an agricultural pest.It is associated with citrus, but it attacks a wide range of … University. The virulence factors of S. aureus include hyaluronidases, lipases, and DNases which allow invasion into a tissue. the rank-based classification, of bacteria.. Sometimes, these measurements are the only differences needed to distinguish between two closely related species. Morphology and culture. capable of causing human disease) No = 0, Yes = 1: Plant pathogen: Does the species causes disease in plants? In the scientific classification established by Carl Linnaeus, each species has to be assigned to a genus (binary nomenclature), which in turn is a lower level of a hierarchy of ranks (family, suborder, order, subclass, class, division/phyla, kingdom and domain). • largest group of human pathogens • Motile or non motile • Found as normal flora in intestinal tract of humans and animals, soil, water. Streptococcus organisms are Gram positive, microaerophilic and non-motile bacteria. Most bacteria are classified into two broad categories: Gram positive and Gram negative. (2) ... Planococcus is a gram POSITIVE cocci. Perform a Gram stain and note the Gram reaction. The gram-stain was repeated three times before a successful stain was accomplished. BACKGROUND. The bacterium was found to be aerobic and Gram-stain positive. 2. These categories are based on their cell wall composition and reaction to the Gram stain test.The Gram staining method, developed by Hans Christian Gram, identifies bacteria based upon the reaction of their cell walls to certain dyes and chemicals. Materials and methods Soil samples were collected at random sites around lake Zub, Schirmacher oasis (70°45'12"S and 11°46'E), Antarctica, in the third week of January 1985. Virulence factors. Clinical Significance: Usually considered contaminants of clinical specimen; rarely implicated as cause of infections. There exist several sources of streptococcus organisms that include humans as well as many animals where they mostly form colonies in the mucosal surface of the mouth, pharynx, etc. Gram positive cocci in clusters, sometimes in pairs and short chains. A novel Gram-stain-positive, coccoid or short rod-shaped, moderate-orange-pigmented, halotolerant and psychrotolerant bacterium, designated strain SCU63 T, was isolated from a saline soil sample in China, and characterized by a polyphasic taxonomic approach.

Perform a nigrosin stain, measure the average cell size and note the spatial cell arrangements from the broth culture given you in the previous session. Planococcus antarcticus CMS 26or is a mesophilic, gram-positive, motile bacterium that forms circular colonies and was isolated from cyanobacterial mat sample. M.A. Bacterial taxonomy is the taxonomy, i.e. 16S rRNA gene sequence similarity of strain SCU63 T to species in the genera Planococcus and Planomicrobium ranged from 96.5 to 98.6 %. Gram Straining is a method of staining used to distinguish and classify bacterial species into two large groups, which are negative or positive. The genus Planococcus was created by 26 to accommodate motile cocci that had previously been classified as micrococci. Academic year. The gram-stain revealed that the isolate was a gram-positive coccid: Image 2. S. aureus is a notorious pathogen. Micrococci are usually not pathogenic. To identify the isolate, please follow the basics. A culture can be grown on blood agar plates. It can form in tetrads or irregular clusters but not in chains and belongs to the family Micrococcaceae. It gives relatively quick, preliminary results as to whether microbes are present and, if so, the general type(s) causing an infection. Strains of E. herbicola are common in the epiphytic microflora of plants; instances have been reported in which E. herbicola has produced symptoms on plants, sometimes possibly in association with other phytopathogenic bacteria. 5 GRAM- Positive- Cocci- Staphylococci. The genus Planococcus was originally proposed by Migula [1] to accommodate Gram-stain-positive, aerobic and motile cocci of the family Planococcaceae in the phylum Firmicutes.
