Metallic wastewater treatment by sulfate reduction using anaerobic rotating biological contactor reactor

Mothe Gopi Kiran, Kannan Pakshirajan, Gopal Das

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 4, doi: 10.1007/s11783-018-1073-4

Abstract:

An-RBC reactor is highly suited to treat metallic wastewater.

Metal removal is due to sulfide precipitation via sulfate reduction by SRB.

Cu(II) removal was the best among the different heavy metals.

Maximum metal removal is achieved at low metal loading condition.

Metal removal matched well with the solubility product values of respective metal sulfide salts.

Cholera: an overview with reference to the Yemen epidemic

Ali A. Rabaan

Frontiers of Medicine 2019, Volume 13, Issue 2,   Pages 213-228 doi: 10.1007/s11684-018-0631-2

Abstract: Cholera is a secretory diarrhoeal disease caused by infection with , primarily the O1 El Tor biotype. There are approximately 2.9 million cases in 69 endemic countries annually, resulting in 95 000 deaths. Cholera is associated with poor infrastructure and lack of access to sanitation and clean drinking water. The current cholera epidemic in Yemen, linked to spread of O1 (Ogawa serotype), is associated with the ongoing war. This has devastated infrastructure and health services. The World Health Organization had estimated that 172 286 suspected cases arose between 27th April and 19th June 2017, including 1170 deaths. While there are three oral cholera vaccines prequalified by the World Health Organization, there are issues surrounding vaccination campaigns in conflict situations, exacerbated by external factors such as a global vaccine shortage. Major movements of people complicates surveillance and administration of double doses of vaccines. Cholera therapy mainly depends on rehydration, with use of antibiotics in more severe infections. Concerns have arisen about the rise of antibiotic resistance in cholera, due to mobile genetic elements. In this review, we give an overview of cholera epidemiology, virulence, antibiotic resistance, therapy and vaccines, in the light of the ongoing epidemic in Yemen.
