Batch Fermentation

Batch fermentation involves the fermentation of the substrate into products by microbial cells. This process occurs within a closed system. Unlike continuous culture, it requires the supply of limited nutrients into the fermentor. Fermentation utilizes a living microbial cell suspension. It produces various valuable products through fermentation of the raw material or substrate. In fermentation, …

Chemical Disinfectants

Chemical disinfectants either destroy, inactivate or inhibit the pathogenic growth. Disinfection eliminates various microbes, except for bacterial spores, using different chemical agents, heat or radiation. It disinfects the inanimate objects. Disinfection is classified into low-level, intermediate-level or high-level. Low-level disinfection is efficient in killing vegetative bacteria and lipid-containing viruses. Intermediate-level disinfection effectively kills bacteria, fungi …

Allosteric Site

The allosteric site of an enzyme is regulatory in function. Enzymes with allosteric or regulatory sites behave as the “Allosteric enzymes”. Such enzymes possess multiple binding sites for both substrates and effectors. Allosteric enzymes are regulated by the non-covalent or reversible binding of effectors or non-substrate molecules to the allosteric site. Thus, the allosteric site …

Euglena Eyespot

Euglena eyespot is also called stigma or eyespot apparatus. It generally has a bright red colour appearance. Euglena is a unicellular photosynthetic organism having an eyespot apparatus as a light-receptive organelle. The red colour of the eyespot in Euglena is due to the presence of carotenoid pigment granules. In addition, it contains photoreceptors, structural, metabolic …

Difference Between Vitreous Humour and Aqueous Humour

The difference between vitreous humour and aqueous humour is primarily in the location within the eye. Vitreous humour is a gelatinous mass occupying the vacant space within the eye lens and the retina. Aqueous humour is a watery fluid occupying the cavity within the cornea and the eye lens. The eye-cavity has distinct two chambers, …
