Rapid biological synthesis of silver nanoparticles from Cymbopogon citratus extract and evaluation of its antimicrobial properties
(BRAC University, 2018-07)It has been well known for many years that silver Nanoparticles (NPs) are toxic to microorganism and can potentially kill them. They can also provide solution to different technological and environmental problems such as ... -
Evaluation of MicrocinE492 gene presence in Klebsiella pneumoniae isolated from clinical samples.
(BRAC University, 2018-10)Bacteriocins are small peptides with anti-bacterial properties. Among which, micrrocin E492 (MccE492) is a low-molecular-weight, channel-forming bacteriocin produced by Klebsiella pneumoniae. However, micrrocin E492 is ... -
Analysis of enteric pathogenicity of multidrug-resistant Pseudomonas spp. isolated from commercial UHT milk
(2018-09)Pseudomonas is a kind of bacteria that has the ability to develop resistance to antibiotics rather rapidly over several generations. This resistance present in some strains makes Pseudomonas a very difficult to treat once ... -
Agrobacterium mediated transformation of two peanut (Arachis hypogaea L.) explants using Na⁺/H⁺ antiporter gene to generate transgenies to resist salinity stress
(BRAC University, 2018-07)Peanut is one of the most popular sources of healthy addible oil. Its susceptance to various biotic and abiotic stresses is limiting crop production worldwide. Salinity is prior to them. Moreover, it is strictly monocious ... -
