Test Result Acid from Glucose Negative (-) (Yellow Pigment) Bacitracin Sensitive Motility Negative (-) nonmotile Nitrate Reduction Positive (+) reaction to Nitrate Click to see full answer. In this way, does Micrococcus luteus reduce nitrate?Micrococcus luteus (Kocur, PBEovB & Martinec, 1972) has a GC content in DNA of 70-7 to 755 %, is asaccharolytic and does not reduce nitrates. Micro- coccus varians (Kocur & Martinec, 1972) has a GC content in DNA of 66 to 72 %, produces acid from glucose, and generally reduces nitrates.Furthermore, does Micrococcus luteus grow on blood agar? Conditions for Growth: It can grow at 45°C and in 10% Sodium Chloride. It will grow on a variety of media including Tryptic Soy Agar, Standard Methods Agar, Nutrient Agar, and Sheep Blood Agar. Also asked, what is the arrangement of Micrococcus luteus? Micrococcus luteus are Gram-positive, to Gram-variable, motile -non motile, that are 0.5 to 3.5 micrometers in diameter and usually arranged in tetrads or irregular clusters. They are generally strict aerobes and can generally reduce nitrate.Is Micrococcus luteus harmful to humans? Key health and ecological effects (hazard) There is no evidence in the scientific literature to suggest that Micrococcus luteus strain ATCC 4698 is likely to have adverse effects on human health. In humans Micrococcus luteus is generally considered to be non-pathogenic and is rarely isolated from damaged tissues.
