Microbial cellulases are enzymes produced by microorganisms that break down cellulose into simpler sugars, playing a crucial role in the decomposition of plant material and the global carbon cycle. They are extensively utilized in industrial applications, including biofuel production, textile processing, and waste management, due to their efficiency in converting biomass into valuable products.
Pulse Code Modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a digital code. It is the standard form of digital audio in computers, compact discs, digital telephony, and other digital audio applications, offering high fidelity and noise immunity.
A jewel case is a compact, transparent plastic case used primarily for packaging CDs, DVDs, and Blu-ray discs, designed to protect the disc from scratches and dust while allowing the cover art and disc label to be visible.

The Red Book Standard refers to a set of guidelines and specifications for the physical and digital production of audio CDs, ensuring compatibility and quality across different players and systems. Established by Philips and Sony, it has become the foundation for the compact disc digital audio format, setting the standard for audio CD manufacturing worldwide.
CD-R (CD-Recordable) is a digital optical disc storage format that allows users to record data once and read it multiple times. It revolutionized data storage and sharing by providing a cost-effective, durable medium for personal and professional use, before being largely supplanted by more advanced technologies.
A CD-ROM is a type of optical disc used to store data that can be read by a computer with a CD-ROM drive. It is a read-only medium, meaning the data on it cannot be modified or erased, making it ideal for distributing software, games, and multimedia content.
