Studies on Agar from <i>Gracilaria confervoides</i> Grev. II

Studies of Agar-digesting Bacteria.

Studies of the Common Aerobic Spore-Forming Bacilli: II. Fermentation Reactions in Agar Butt-Slants.

Despite the well-recognized need for simple means of identifying the common varieties of aerobic spore-bearing bacilli little attention has been given to the fermentative reactions of these organisms. Most descriptions mention tests with glucose, lactose, sucrose, and maltose only and the reactions have generally been regarded as of no differential value. Liquid culture media have apparently be...

Differentiation of Candida dubliniensis from Candida albicans on rosemary extract agar and oregano extract agar.

Candida dubliniensis is a recently described pathogenic species which shares many phenotypic features with Candida albicans and therefore, may be misidentified in microbiological laboratories. Because molecular methods can be onerous and unfeasible in routine mycological laboratories with restricted budgets such as those in developing countries, phenotypic techniques have been encouraged in the...

Differentiation of Candida dubliniensis from Candida albicans on staib agar and caffeic acid-ferric citrate agar.

The methods currently available for the identification of the pathogenic yeast Candida dubliniensis all have disadvantages in that they are time-consuming, expensive, and/or, in some cases, unreliable. In a recent study (P. Staib and J. Morschhäuser, Mycoses 42:521-524; 1999) of 14 C. dubliniensis and 11 C. albicans isolates, it was suggested that the ability of C. dubliniensis to produce rough...

Removal of Hg(II) and Cd(II) Ions from Aqueous Solution Using Chitosan: Kinetics and Equilibrium Studies

Background and purpose: The discharge of toxic heavy metal ions into the environment is a serious pollution problem. Heavy metal ions pose adverse toxic risks to human health at very low concentrations. The aim of this paper is the adsorption potential of chitosan (CS) in the removal of Hg(II) and Cd(II) ions from aqueous solution. Materials and Methods: This study was conducted in laboratory s...
