Roseomonas lacus is a species of Gram negative, strictly aerobic, coccobacilli-shaped, pale pink-colored bacterium. It was first isolated from a freshwater sediment from Lake Tai in Jiangsu province, China, and the species was first proposed in 2006. The species name comes from Latin lacus (lake).

Lake Tai or Lake Taihu is a large freshwater lake in the Yangtze Delta plain. The lake belongs to Jiangsu and the southern shore forms its border with Zhejiang. With an area of 2,250 square kilometers (869 sq mi) and an average depth of 2 meters (6.6 ft), it is the third-largest freshwater lake in China, after Poyang and Dongting. The lake houses about 90 islands, ranging in size from a few square meters to several square kilometers.

China, officially the People's Republic of China (PRC), is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering approximately 9,600,000 square kilometers (3,700,000 sq mi), it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, and the special administrative regions of Hong Kong and Macau.

Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, and ultimately from the Phoenician alphabet.

The optimum growth temperature for R. lacus is 30 °C, but can grow in the 15-40 °C range. The optimum pH is 7.0, and can grow in pH 6.0-9.0.^[1]

In chemistry, pH is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions. More precisely it is the negative of the base 10 logarithm of the activity of the hydrogen ion. At 25 °C, solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic. The neutral value of the pH depends on the temperature, being lower than 7 if the temperature increases. Pure water is neutral, pH 7 at (25 °C), being neither an acid nor a base. Contrary to popular belief, the pH value can be less than 0 or greater than 14 for very strong acids and bases respectively.
