“…The mating analysis has also been found which was comparative that this species structure is flexible in comparison with other species in the same genus. The topology length of the species genome is found to be three times bigger with the species (Silva et al, 2012). Rhizopus species are able to produce different types of compounds of an enormous industrial importance i.e., enzymes and organic acids.…”

Soil is loaded by microbes which are capable of producing antibiotics. These compounds were used therapeutically and sometimes prophylactically in the control of infectious disease. Soil microbes can be grouped into Bacteria, Actinomycetes, Fungi, Algae, Protozoa and Nematodes. Fungi are unique eukaryotes which ingest food from outside and take nutrients through its cell walls and consists of tiny tubular mycelia known as hyphae. The fungi are well known in medical field due to the production of a wide variety of secondary metabolites. The current research study was focused on isolation, identification and antibacterial activity of fungi isolated from rhizosphere of Mentha Piperita (Mint), Abasyn University, Peshawar. The research study was conducted in the Microbiology Research Laboratory (MRL) of Abasyn University Peshawar. The soil sample was collected from rhizosphere by using sterile techniques. Serial dilution method was used to dilute the concentration of microbes present in soil sample. The Potato Dextrose Agar media was prepared and by pour plate method the sample was streaked on the plate. The plates were incubated at 280C for 72hours. The fungus was isolated by sub culturing technique and then identified by morphological and microscopic examination using Lactophenol cotton blue stain (LPCB).

“…Studies aiming to explore the biotechnological potential of genus Rhizopus have demonstrated that species of this genus are able to produce different types of compounds of an enormous industrial importance, namely enzymes (Freitas et al, 2014), organic acids (Abe et al, 2007), chitin, and chitosan (Berger et al, 2014) including biosurfactant (Freitas Silva et al, 2012).…”

This study screened four Rhizopus species as biosurfactant producers using different markers. First of all, Rhizopus spp. UCP 1607 was identified as Rhizopus arrhizus by morphological and molecular methods. The production of biosurfactant/bioemulsifier was investigated by submerged fermentation using soybean post-frying oil (5% v/v) and sodium glutamate (1% w/v) medium. The primary markers' hemolysis and parafilm M tests showed that R. arrhizus UCP1607 strain exhibited higher hemolytic activity (49 mm of clear zone) on sheep blood agar and a larger drop diameter (12 mm) on parafilm hydrophobic surface. The experimental results showed the most promising biosurfactant production by R. arrhizus UCP 1607 strain led to a reduction of surface tension (31.8 mN/m) and the diameter of the oil-spreading covered an area of 66.4 cm 2 . The strains Rhizopus microsporus var. chinensis UCP1296, R. microsporus var. microsporus UCP1304, and R. arrhizus UCP1607 were capable of forming stable emulsions corresponding to 91.7, 94.8, and 82.6%, respectively in crude oil.
