The usaul contaminate in beer are bacterium,fungus and wild yeast, most of them are anaerobion causing the muddy, flavor chaging and turning sour, Beer anaerobic culture medium should be found out.
Because it is hard to industrify the production of the targeting-medicant by this method ,we decide to research the expression of apoAI gene in methytrophic yeast Pichia pastoris system .
They grow as single cells that reproduce by asexual budding and oval or round in shape. Some yeast produce chains of elongated cells (pseudohypha) that resemble the mycelium of molds.
The biotechnology of flask batch and fed-batch culture to produce yeast from cornhusk hydrolysate was studied and the fed -batch process in 10L bioreactor was conducted.
Objective:Aspergillus niger and Candida mycoderma was used to ferment Daqu distiller's grain to produce single cell protein feed with the additive of glucoamylase and cellulose.
Accelerating the aging of new wine and new vinegar, sterilizing fermented foods and mutagenizing Saccharomyces cerevisia by modern physical technology were reviewed in this paper.
Hordenine propyl formate and chemical osmosis are the two ways of extracting Glutathione(GSH) from yeast have been introduced and compared in this review.
Enzyme preparation (Diastatic Enzyme) is partially substituted for daqu and active dry yeast (ADY) is partially substituted for yeast culture to produce spirits.
Cold maceration before fermentation; alcoholic fermentation with endogen yeasts; 27-days vatting with micro-oxygenization; Malo-lactic fermentation in vats; 12-months ageing in French oak barrels.
The paper introduces their salt-tolerance mech anism and research progress regarding conventional anaerobic or aerobic sludge, halophile and salt-tolerant yeast.
(-)-Methyl mandelate was produced by asymmetric reduction of methyl benzoylformate catalyzed by Saccharomyces cerevisiae LH1 screcned by our laboratory.
The Master Cleanse can ever lead to a white tongue, which some claim is the toxins leaving your body, but it’s actually due to swelling and a yeast infection of the mouth.
