Aspergillus niger is a filamentous fungus found throughout nature, notably in soil and decomposing organic waste. It belongs to the Aspergillus genus and is distinguished by its black conidial heads. Aspergillus niger is well-known for its industrial and biotechnological uses, but it is also a prevalent food and indoor contamination source. This overview delves into […]
Spectroscopy is the study of the interaction of matter and electromagnetic radiation to examine and identify substances based on their distinct spectral patterns. It entails determining how much light is absorbed by a chemical compound and at what intensity it goes through. They are determined by evaluating the radiant energy absorbed or emitted by the

RNA, also known as ribonucleic acid, is a nucleotide polymer composed of ribose sugar, phosphate, and bases such as adenine, guanine, cytosine, and uracil. Different Types of RNA RNA polymerase produces RNA from DNA that is either protein-coding (messenger RNA, mRNA) or non-coding (RNA genes). Because of their functionalities, they are classified into following types
Glycoprotein molecules called immunoglobulins, or antibodies, are made by plasma cells, which are white blood cells. They are essential to the immune response because they can identify and attach to certain antigens, such germs or viruses, and help destroy them. Types of Immunoglobulins Immunoglobulins, another name for antibodies, are proteins that lymphocytes make in response
5 Types of Immunoglobulins: IgG, IgM, IgA, IgD, and IgE Read More »
Certainly! Let’s delve into the fascinating world of acetate utilization test. Acetate utilization test is a biochemical test used to determine whether an aerobic organism is present in the growth media which measures the organism’s capacity to use acetate. This test aids in the identification of a specific group of organisms based on their metabolic

Action Potential : The rapid (less than a thousandth of a second) reversal of the electric polarization of the membrane of a muscle or nerve cell. In muscle cells, it starts the contraction required for movement, and in neurons, it produces the nerve impulse. Definition of Action potential The quick (less than a thousandth of

Active vs. Passive Transport: Differences and Examples Active transport is the process by which molecules move across a cell membrane while being pumped against a concentration gradient by ATP, or energy. Passive transport is the movement of molecules through the concentration gradient and across the cell membrane without the use of ATP, or energy. Active

The Kinyoun Cold Method is a modified version of the traditional Ziehl-Neelsen acid-fast stain technique used for identifying acid-fast bacteria, particularly Mycobacterium species such as those causing tuberculosis and leprosy. This method, developed by Joseph Kinyoun, does not require heating (“cold” method), making it simpler and safer for routine laboratory use. Here’s an overview of

Biology has been interested in the topic of adrenal glands over the years because of their diverse structure, intricate neurological connections, multitude of physiological activities, and large hormone production. The adrenal glands, also called suprarenal glands, are a pair of glands occurring on the top of kidneys and produce different steroid hormones.Hormones produced by this
