    Taxonomical establishment and compositional studies of a new cordyceps (ascomycetes) species from the northwest himalayas (India)
    (Begell House Inc., 2016) Sharma, S.K.; Gautam, N.; Atri, N.S.; Dhancholia, S.
    During a frequent survey in the northwest Indian Himalayan region, a new species-Cordyceps macleodganensis-was encountered. This species is described on the basis of its macromorphological features, microscopic details, and internal transcribed spacer sequencing. This species showed only 90% resemblance to Cordyceps gracilis. The chemical composition of the mycelium showed protein (14.95 ? 0.2%) and carbohydrates (59.21 ? 3.8%) as the major nutrients. This species showed appreciable amounts of ?-carotene, lycopene, phenolic compounds, polysaccharides, and flavonoids. Mycelial culture of this species showed higher effectiveness for ferric-reducing antioxidant power, DPPH radical scavenging activity, ferrous ion-chelating activity, and scavenging ability on superoxide anion-derived radicals, calculated by half-maximal effective concentrations. ? 2016 Begell House, Inc.

    Treatment of seafood processing wastewater using upflow microbial fuel cell for power generation and identification of bacterial community in anodic biofilm
    (Academic Press, 2016) Jayashree, C.; Tamilarasan, K.; Rajkumar, M.; Arulazhagan, P.; Yogalakshmi, K.N.; Srikanth, M.; Banu, J.R.
    Tubular upflow microbial fuel cell (MFC) utilizing sea food processing wastewater was evaluated for wastewater treatment efficiency and power generation. At an organic loading rate (OLR) of 0.6 g d-1, the MFC accomplished total and soluble chemical oxygen demand (COD) removal of 83 and 95%, respectively. A maximum power density of 105 mW m-2 (2.21 W m-3) was achieved at an OLR of 2.57 g d-1. The predominant bacterial communities of anode biofilm were identified as RB1A (LC035455), RB1B (LC035456), RB1C (LC035457) and RB1E (LC035458). All the four strains belonged to genera Stenotrophomonas. The results of the study reaffirms that the seafood processing wastewater can be treated in an upflow MFC for simultaneous power generation and wastewater treatment. ? 2016 Elsevier Ltd.
