1. Keep the tax laws simple, small businesses don't have the resources to deal with complexity.
2. Don't penalize the successful. Tax businesses based on value-added rather than net income. In an income tax situation, a poorly run business pays no tax and a good one pays a lot. With value-add taxing two similar businesses will pay similar tax, regardless of profitability.
A laboratory medium is a substance used to support the growth of microorganisms or cells in a controlled environment. It typically consists of nutrients such as amino acids, sugars, and minerals to promote growth and is used for experiments and research in microbiology, molecular biology, and cell biology.
Bacterial growth within a culture of medium can be limited by factors such as nutrient availability, pH levels, temperature, oxygen levels, and the accumulation of waste products. These factors can either promote or inhibit bacterial growth depending on their specific conditions.
selective medium
• Basal Medium - contains no growth factors cytokines, or supplements• Supplement Kit - growth factors, cytokines, and supplements• Medium Kit - basal medium and Supplement Kit packaged together
EMB agar is a complex undefined medium because it contains multiple components such as peptone, lactose, agar, and eosin Y and methylene blue dyes that promote the growth of a wide variety of bacteria while inhibiting the growth of certain Gram-positive bacteria.

An enrichment medium is a type of culture medium that is specifically designed to support the growth of a particular group of microorganisms while inhibiting the growth of others. It typically contains nutrients that promote the growth of the desired microorganisms, allowing them to multiply and be detected more easily. Enrichment media are commonly used in microbiology to isolate and identify specific bacteria from complex samples.

Xanthomonas isolation agar is a specialized medium used to isolate Xanthomonas species, which are plant-pathogenic bacteria. This medium contains specific nutrients and inhibitors to suppress the growth of other bacteria and promote the growth of Xanthomonas. It is used in microbiology laboratories for the selective isolation and identification of these bacteria from plant samples.

BHI medium (Brain Heart Infusion medium) is a nutrient-rich liquid or agar medium used for the cultivation and maintenance of fastidious microorganisms. It contains brain and heart extracts as well as other nutrients that promote the growth of bacteria, particularly those with complex nutritional requirements. BHI medium is commonly used in microbiology laboratories for the isolation and cultivation of a variety of bacteria, including pathogens and anaerobes.

HS medium refers to Heart infusion-Serum (HS) broth or agar, a type of nutrient medium commonly used in microbiology to grow and cultivate a variety of bacteria. It contains heart infusion broth supplemented with animal serum, providing essential nutrients and growth factors for bacterial growth. HS medium is particularly useful for fastidious bacteria that require specific nutrients for growth.
A basal medium is a growth medium which incorporates a genetic material such as yeast extract of unknown precise composition.
Simple medium contains a basic nutrient source for the growth of microorganisms, while complex medium contains more complex ingredients such as extracts from plants or animals. Complex medium usually provides a wider range of nutrients to support the growth of diverse microorganisms compared to simple medium.
