Choose the correct statement/s from the codes given below
The correct option is C c) Both 1 and 2
1. Coliform bacteria are defined as rod-shaped Gram-negative non-spore forming and motile or non-motile bacteria which can ferment lactose with the production of acid and gas when incubated at 35–37°C.
2. They are a commonly used indicator of sanitary quality of foods and water. Coliforms can be found in the aquatic environment, in soil and on vegetation; they are universally present in large numbers in the feces of warm-blooded animals.
3. While coliforms themselves are not normally causes of serious illness, they are easy to culture, and their presence is used to indicate that other pathogenic organisms of fecal origin may be present Such pathogens include disease-causing bacteria, viruses, or protozoa and many multicellular parasites.
4. The permissible limit as per the Central Pollution Control Board (CPCB) guideline is 500.
