Mushroom, a nutrient-dense versatile food can share some of the benefits of fruits and vegetable and complement almost any everyday meal. Mushroom cultivation also requires low technology, low investment and can be grown in very little space. Due to culinary, nutritional and health benefits, the mushroom market is expected to grow as "a food, a tonic and a medicine". In the study food value of mushroom was found comparatively higher than that of other vegetables, fruits, meat and fish. This discussion suggests that the potentiality of mushroom cultivation could be a possible offer to alternate food and develop the life style of the people.
Present study endeavored to evaluate the microbial contamination level along with their
drug resistant pattern in some popular desert food items collected from different food
shops in Dhaka city, Bangladesh. The microbial evaluation was conducted through
conventional cultural methods and drug susceptibility test was executed through disc
diffusion method. All the samples were found to be contaminated with heterotrophic
bacteria as well as fungi within the range of 103
to 105 CFU/g. In case of specific
microflora, the growth of Staphylococcus spp. was very high in sweet, faluda, milk cake
and ice cream as estimated up to 105 CFU/g, halua and sweet yogurt showed 104 CFU/g
while rest of the samples revealed 103 CFU/g. E. coli was found only in faluda and ice
cream up to 103 CFU/g whereas Klebsiella spp. was estimated in all the samples within the
range of 102 CFU/g to 105 CFU/g. Salmonella spp., Pseudomonas spp. and Bacillus spp.
were totally absent in all the samples. Most of the isolates were found to be resistant
against most of the antibiotics. Meanwhile, streptomycin (10 µg), gentamicin (10 µg),
azithromycin (15 µg), and nalidixic acid (5 µg) were effective drug against both E. coli
and Staphylococcus spp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
