Abstract

A Virus is an individual that cannot be described as an animal or a plant. If animals and plants contain two nucleic acids (DNA and RNA), on the contrary, the virus only has one of them. These nucleic acids can stimulate a complete virus replication cycle. The virus can only replicate and live on a living host if the host is finally dead, then the virus will move on the cells that are still alive. The virus has genetic material which is a protective protein coat called a capsid. Viruses can infect various varieties of organisms, both eukaryotes (animals, plants, protists, and fungi) and prokaryotes (bacteria and archaea). The Virus infects bacteria known as bacteriophage (phage). The Virus can cause serious diseases for humans such as AIDS, HIV, rabies, etc. Dogs belonging to Canidae family are the sibling of wolves, foxes and raccoon dogs. Among all members of Canidae, dogs have the most closely related to wolves which are the ancestors of dogs. The Canidae family generally has a small elongated body, sharp ear and muzzle, sharp smelling, can run fast and can swim. Dogs are human best friends. While taking care of the dogs, they can be attacked by various diseases. The closeness of the relationship between humans and dogs raises the potential for disease transmission, especially zoonosis and pandemics viruses.

Abstract

Porong River is an active river located in the Sidoarjo region, East Java which has been polluted by the Lapindo mudflow containing various chemical compounds, one of which is lead (Pb) heavy metal. Isolation of bacteria in the environment contaminated with Pb allows bacteria that have the potential as bioremediation agents to grow. The purpose of this study was to determine the content of heavy metal Pb and isolate and identify lead (Pb) tolerant bacteria in water and sediment at Porong river, Sidoarjo. Sampling of water and sediment was carried out at 2 sampling points based on the presence of Lapindo mud waste flow. Analysis of the heavy metal content of Pb was carried out using the Atomic Absorption Spectrophotometer (AAS). Bacterial isolation was carried out on NA media containing 10 ppm Pb of heavy metal and incubated for 24 hours at 300C. Bacterial isolates were identified based on the macroscopic and microscopic properties and biochemical tests. The results of the heavy metal content of Pb at sampling point 1 in water was 0.81 ppm, and in sediment was 0.98 ppm while at sampling point 2 in water was 2.93 ppm, and in sediment was 3.88 ppm. The results of bacterial identification obtained as many as 6 bacterial isolates belonging to 3 genera of bacteria including Bacillus, Acinetobacter and Pseudomonas.
