Antimicrobial potential of chitosan

Chitosan is a biopolymer that has been used in the production of biomaterials and is the focus of numerous studies due to its antimicrobial activity. Chitosan has high value-added applications in medicine, agricultural and cosmetics. Its broad spectrum of action, strong bactericidal/bacteriostatic activity and low cytotoxicity are some of the many advantages of chitosan as an antimicrobial agent. This paper consists of...

Evaluation of antagonists against Macrophomina phaseolina causing root rot of groundnut

Efficacy of antagonists isolated from rhizosphere was tested against different isolates of Macrophomina phaseolina collected from groundnut growing areas of Rajasthan and adjoining states. One isolate of Trichoderma harzianum, one isolate of Trichoderma viride and one isolate of Bacillus subtilis gave distinct antagonistic reactions against all the isolates of M. phaseolina in dual culture plate method. T. viride, T....

Culture media evaluation for biosurfactant production by Pseudomonas putida CB-100 using Plackett-Burman experimental design

Oil and fat wastes produced by food industries are hydrophobic compounds that are difficult to remove from contaminated sites, that is why they are an important environmental issue. Biosurfactants can be used to enhance the accessibility of these compounds to microorganisms for degradation. The aim of this study was to determine favorable nutrient and culture conditions for biosurfactant production by Pseudomonas putida...

Prevalence of beta-lactamases in Salmonella and Shigella species in different hospitals in Anyigba, Kogi State, Nigeria

Beta-lactams are the most widely used antibiotics. Resistance to beta-lactam antibiotics is an increasing problem worldwide and beta-lactamase production is the most common mechanism of resistance to these drugs. Species of Salmonella and Shigella isolated from hospital patients in Anyigba, Kogi State, were analyzed for the presence of beta–lactamases using Nitrocefin, Iodometric, Acidimetric and Double Disc...

Morphological characteristics of wet bubble disease (Mycogone perniciosa) isolated from button mushroom (Agaricus bisporus) and assessment of factors affecting disease development and spread

Wet bubble disease (Mycogone perniciosa) is a devastating disease in the crop production of mushrooms. In India, it has been reported to cause serious crop losses. It is also a common contaminant, occurring in mushroom houses in the Kashmir valley. The aim of the study was to investigate physiological characteristics of M. perniciosa isolated from button mushroom (Agaricus bisporus). The assessment of the factors...

Molecular identification of fungal species associated with leaf lesions of marama bean seedlings in Namibia

During one of our greenhouse experiments on the marama bean plant (Tylosema esculentum) at the University of Namibia, various signs of necrosis and spotting were observed on leaf tissues of the newly developed seedlings. In this study, we hereby describe findings of the investigations undertaken to attempt and determine the possible causative agent(s) of such plant leaf infections. In brief, infected seedling leaves...
