Research ArticleOpen accessIn the abstractBlood Biochemical Profiles and Pregnancy Rate of Brahman Crossbred Cows Supplemented with Mineral MixtureMohammad Sofi’ul Anam, Ali Agus, Lies Mira Yusiati et al.The investigation was expected to assess various mineral mixture supplementation impacts on Brahman crossbred cows' blood biochemical, hematological profiles and pregnancy rate. This study used ninety Brahman crossbred cows divided into three dietary treatment groups (n = 30/group). The dietary treatments were: Concentrate and rice straw only as control treatment; control diet + mineral mixture A-formulation as MM-A treatment; and … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 3 · 15 Sep 2021 · 6,771 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCharacterization of a Multi-Metal Resistant Bacillus cereus Strain TWSL_5 and it’s Bioremediation Potential for Cr, Pb, Zn and FeWeerasingha Mudiyanselage Nilmini Hasintha Kumari, Naduviladath Vishvanath Chandrasekharan, Champika Dilrukshi WijayarathnaAn effluent sample collected from a textile dyeing factory was screened to isolate metal resistant endogenous bacteria using standard microbiology techniques. A bacterium with the highest metal resistance was characterized by 16S rRNA gene sequencing and the bacterial genome was screened for any possible metal resistant genes using the Polymerase Chain Reaction (PCR). The bioremoval ability of the isolate was … …American Journal of Environmental Sciences, Vol. 17, Issue 3 · 15 Jul 2021 · 6,448 accessesView PDF Cite
