This special issue is dedicated to the study of microbial enzymes and their applications in various industries. The biocatalytic uses for enzymes have grown immensely in recent years since they are ecologically correct, have a high specificity, present chemo-regio-enantio selectivity, and have a wide diversity of reactions. Moreover, the conditions to obtain and optimize the production of enzym...

Refined vegetable oils are the predominant feedstocks for the production of biodiesel. However, their relatively high costs render the resulting fuels unable to compete with petroleum-derived fuel. Artificial neural network (ANN) analysis of immobilized Candida rugosa lipase (CRL) on chitosan catalyzed preparation of biodiesel from rapeseed soapstock with methanol was carried out. Methanol subs...

Marine microorganisms are of considerable interest as a promising source of enzymes with unsuspected potentials as catalysts for chemical synthesis. We describe here an efficient method for one-pot indolizine synthesis that has been developed using lipase A and lipase B from Candida antarctica as biocatalysts. As showed by HPLC/MS analysis, the yield in indolizines was higher in the presence of...

A total of 80 Candida isolates representing 14 species were examined for their respective responses to an in vitro hemolytic test. A modification of a previously described plate assay system where the yeasts are incubated on glucose (3%)-enriched sheep blood agar in a carbon dioxide (5%)-rich environment for 48 h was used to evaluate the hemolytic activity. A group of eight Candida species whic...

A new system, Micronaut-Candida, was compared to API ID32C to identify 264 yeast (Candida albicans, C. parapsilosis, C. tropicalis, C. krusei, C. inconspicua, C. norvegensis, C. lusitaniae, C. guilliermondii, C. dubliniensis, C. pulcherrima, C. famata, C. rugosa, C. glabrata, C. kefyr, C. lipolytica, C. catenulata, C. neoformans, Geotrichum and Trichosporon species, Rhodotorula glutinis, and Sa...

Introduction: Recovery of evidence such as murder weapons in waterways has been commonly reported. However, visualising latent fingerprints on the immersed substrates may prove challenging due to its obliteration by physicochemical parameters (e.g. pH, temperature, salinity) well mechanical effect water. Although use Small Particle Reagent (SPR) for wet non-porous suggested, it contains molybde...

Pentyl valerate was synthesized biocatalytically using Candida rugosa lipase (CRL) immobilized in microemulsion based organogels (MBGs). The optimum conditions were found to be pH 7.0, temperature of 37 °C, ratio of concentration of water to surfactant (Wo) of 60, and the surfactant sodium bis-2-(ethylhexyl)sulfosuccinate (AOT) for MBG preparation. Although kinetic studies revealed that the enz...
