CHAPTER II
REVIEW OF RELATED LITERATURE AND STUDIES

Mung bean, also known as Vigna radiata and by its common names green gram or

simply as mung, is a small green legume that is the smallest member of the bean family.

It resembles a small whole bean that is encased by a green husk. Mung beans can be

consumed raw or cooked in their whole or split form. They can be fermented; dried and

crushed into a powder which resembles flour, or the seeds can be sprouted. Mung beans

are cultivated all over Asia, as well as in Europe, Canada, and The United States (Yi-

Shen, Shuai et al. 2018).

Mung beans contain potassium, which has the opposite effect of sodium on the

body. Potassium increases the excretion of sodium in the kidneys, which draws water

with it. Lower blood volume lowers blood pressure and allows our blood vessels to relax

(McDonough & Nguyen, 2012).

Fiber makes us feel fuller by slowing down the time it takes for food to pass

through our digestive system. This prevents our blood sugar from spiking, leading to

better blood sugar control throughout the day. Fiber also lowers “bad” cholesterol in our

body, by preventing bile salts from being reabsorbed in the small intestine (Gunness &

Gidley, 2010).

Mung beans have a lot of folate and antioxidants. Folate helps to lower

inflammation through the decreasing the number of inflammatory factors (macrophages)

in our body (Kolb & Petrie, 2013). While the antioxidants such as phenolic acids within

mung beans also combat inflammation by neutralizing free radical damage (Shahidi &

Yeo, 2018).

In Asia, mung beans have been used in various cuisines and in folk remedies to

treat toxic poisoning, heat stroke associated with thirst, irritability, and fever; these

beneficial effects of mung beans are thought to be related to the inflammatory response

(Food Sci Biotechnol. 2011).

Researchers have analysed the anti-inflammatory effects of mung bean ethanol

extracts on lipopolysaccharide (LPS)-stimulated macrophages. The extract mainly

included polyphenols, gallic acid, vitexin, and isovitexin and markedly reduced the

activity of murine macrophages through the prevention of pro-inflammatory gene

expression without cyto Moreover, a study demonstrated that all pro-inflammatory

cytokines, including interleukin (IL)-1β, IL-6, IL-12β, tumor necrosis factor (TNF)-α,

and inducible NO synthase (iNOS), were dramatically down regulated in cells treated

with 3.7 mg/mL polyphenols. These results suggested that the ethanol extract had great

potential to improve the clinical symptoms of inflammation-associated diseases, such as

allergies and diabetes

Toxicity Biomed (Biotechnol. 2012).

Nitrogen (N) and phosphorus (P) are often referred to as the primary

macronutrients because of the probability of plants being deficient in these nutrients and

the large quantities taken up from the soil relative to other essential nutrients (Marschner,

2015). Nitrogen plays an important role for optimum yield of onion and is found to be

essential to increase the bulb size and yield. Increasing nitrogen application rates

significantly enhances plant height, number of green leaves per plant and weight of bulb,

marketable yield and also total soluble solids (Nasreen et al., 2017; Al-Fraihat, 2018).

Bio fertilizer can be expected to reduce the use of chemical fertilizer and

pesticide. The microorganism in the bio fertilizer restores the soil natural nutrient cycle

and builds soil organic matter. Through the use of bio fertilizers healthy plant can be

grown while enhancing the sustainability and health soil

(http://vasat.org/crops/MN/organicFAQs/biofertilizer.htm).

Bio fertilizer is a substance which contain living microorganism which when we

applied to seeds, plant surface, or to soil colonize the Rhizosphere or the interior of the

plant and promotes growth by increasing the supply or ability of the primary nutrients to

the host plant .It also add nutrients through the natural processes of nitrogen fixation,

solubilizing phosphorus, and stimulating plant growth, through the synthesis of growth

promotion substances (http://vasat.org/crops/MN/organicFAQs/biofertilizer.htm).
