trichoderma is one of the important biocontrol agents for certain plant disease that control with different mechanisms. this fungus similar to other biocontrol agents is under the influence environmently factors. medium is one of these factors. this study was investigated effect of the medium (mol.c.b.m.) containing sugar beet molasses, corn steep liquor, baker’s yeast and malt extract as the l...

in this study, the effect of carbon and nitrogen sources, on production of yeast biomass was determined as well as the efficacy of various formulations of candida membranifaciens to decrease blue mold on apple. the media containing sugar cane molasses as carbon sources caused more yeast growth than the media supplemented with permeate powder. yeast extract as nitrogen source produced higher bio...

The objective of this work was to evaluate the potential biohydrogen production in agro-industrial residues, which were soft drink wastewater (SDW), corn steep liquor (CSL), cheese whey (CW), and expired Guaraná drink, using one model strain Clostridium beijerinckii ATCC 8260 newly isolated butyricum DEBB-B348. residues characterized, all them contained significant concentrations carbohydrates ...

Microbial contaminations represent an important issue for crop production, resulting in tons of losses worldwide every year. One the highest-risk pathogens involved these infections is Botrytis cinerea, which responsible grey mold disease. In this study, a biosurfactant extracted from corn steep liquor (CSL), agro-industrial residue corn-milling industry, was used combination with copper oxychl...

The demand for natural pigments industrial applications has significantly increased. Penicillium brevicompactum was recently reported as a promising producer using submerged fermentation and synthetic culture medium containing lactose. In this work, pigment production by P. studied under different conditions, namely, with free (SmF) immobilized mycelium (SmFi), solid-state (SSF). potential of m...

BACKGROUND Lignin peroxidase (LiP) is the primary enzyme responsible for lignin degradation. In our previous work, in order to shorten the pretreatment time and increase the lignin degradation, we have pretreated the corn stalk (CS) using a combination of Aspergillus oryzae CGMCC 5992 solid-state fermentation and H2O2 treatment. RESULTS In the present study, one-factor-at-a-time design and re...
