The present work was carried out with an aim to isolate an Exo-pectinase producing fungal strain, to optimize physical factors of the enzyme activity and to formulate a media for the cost effective production of the enzyme. Screening, isolation and identification of Aspergillus tamarii and Aspergillus carbonarius were done. Various process variables like pH, temperature and incubation time of t...

Mycotoxins are microbial agents which cause food or feed-borne intoxications. Mycotoxins are undesireable compounds often found in cereal grains and forages. Production of mycotoxins is dependent on environmental conditions and agricultural practices. Moisture level ranges between 13% to 18% and temperatures between 20 C and 30 C can increase fungal growth rate during growing seasons as well as...

Amblyomma rotundatum is a tick species commonly found on reptiles and amphibians. In Brazil, investigations of this ectoparasite have indicated its distribution across all Brazilian biomes, although it concentrated in certain locations. context, the objective present study was to describe case parasitism by A. red-footed tortoise (Chelonoidis carbonarius) state Rio de Janeiro. A female (C. carb...

Most biosurfactants are obtained using costly culture media, which limits their wider industrial use. In the present study, a low-cost medium, containing agro-industrial residue black cumin cake, was developed for amphisin production by Pseudomonas fluorescens DSS73. By cake as substrate, not only cost reduced but also higher yield achieved. A Box-Behnken experimental design applied to maximize...
