Spore diversity

Cocci-shaped Sporosarcina strains are currently one of the few known cocci-shaped spore-forming bacteria, yet we know very little about the genomics. The goal of this study is to utilize comparative genomics to investigate the diversity of cocci-shaped Sporosarcina strains that differ in their geographical isolation and show different nutritional requirements.

Zooplankton holds a key position in the food web as it was directly related to the consumption of organic energy produced by phytoplanktonic photosynthesis and then by transforming it to the higher tropical levels of hetirotropes such as fish. Some zooplankton population disappeared at a specified period and reappeared during other period. This disappearance may be due to the fact that some species occur in spores, under favorable conditions spore germinate and appear as zooplankton.

We investigated the diversity of AM fungi in Dalli-Rajhara (Chhattisgarh, India) mine overburden (OB) dump and compares with natural forest soils of adjoining areas. Soil samples were collected from rhizosphere region of planted and naturally growing tree species in mine OB dump. AM spore was isolated by wet sieving and decanting and sucrose floatation method, spore density (per 100g dry soil) was calculated.

Fusarium oxysporum f. sp. cumini is a serious disease of cumin (Cuminum cyminum L.). Ten isolates of F. oxysporum f. sp. cumini were isolated from major cumin growing districts of Gujarat state to compare molecular methods over traditional for differentiation among the isolates of pathogen. The average 98.70 % of polymorphism was recorded for all the 11 ISSR primers. The polymorphic information content (PIC) value ranged from 0.571 to 0.831 with an average of 0.739 per primer. The IISR primers grouped majority of the isolates based on their geographical location.

Investigation has been taken up to reveal the spore diversity of Arbuscular Mycorrhizal (AM) fungi in the soils of five different agro-climatic zones of Andhra Pradesh. Maximum AM fungal spore number was recorded in Central Telangana Zone (47) followed by North Telangana Zone (32.4) per 100g of soil. The lowest spore number was recorded in Godavari Zone (31) followed by Krishna Zone (30.6) and North Coastal Zone (30.5) of Andhra Pradesh.

Cultural and morphological variability studies on three different media viz., Potato Dextrose Agar, Richard’s Synthetic Agar and Czapek’s Dox Agar revealed considerable variation among the isolates of A. burnsii indicated the existence of variability in the pathogen. Moreover, Potato Dextrose Agar and Czapek’s Dox Agar were found as an excellent media to support the growth and spore formation of isolates of A. burnsii, respectively.

The aim of this study was to isolate and optimize the growth conditions of thermophilic microorganism from hot springs. The isolation was conducted by using the mineral salt basal medium supplemented with 0.6% yeast extract at 500C. Totally, 33 isolates of thermophilic microorganism were isolated from hot springs at Truong Xuan (Khanh Hoa province) and Binh Chau (Ba Ria - Vung Tau province). The effects of temperature (45 - 800C), pH (pH 6 - 9) and carbon sources (malate, pyruvate, acetate, glucose, fructose, or carbon dioxide) on the growth of isolates were examined.

Entomopathogenic fungi suppress the diverse group of insect pest such as coleopterans, lepidopterous and sucking pest. Wide spread incidence of Aspergillus niger, Aspergillus flavus and Aspergillus tamarii was observed during extensive and repeated survey covering different agro ecological niches of Dhule, Nandurbar, Jalgaon, Nasik and Beed districts of Maharashtra (India) on insect cadavers infected with fungi. From the insect cadavers the fungal isolates were isolated on PDA media.

Arbuscular mycorrhizal status of Pippali a medicinal plant species in the Jorhat district of Assam, India were surveyed during 2018. Percent colonization, spore density and diversity of arbuscular mycorrhizal fungi associated with the rhizospheric soil and roots of pippali growing wild as well as under cultivated conditions were investigated. It was found that 100% of the surveyed sample was of mycorrhizal infestation. The spore colonization per cent of AMF ranged from 30.80 to 66.50% spores per 100 g of soil. The maximum spore population (185.

This field study was performed to demonstrate that Bacillus aquimaris SH6 spores administered as a feed supplement in adequate amounts confer beneficial effects to the whiteleg shrimp. Shrimps were administered either B. aquimaris SH6 spores at 1×106 CFU g-1 pellet (SH6 group) or a mixture of SH6 and B. subtilis SH23 spores at 5×105 CFU g-1 pellet for each strain (SH6-SH23 group). After a 28-day feeding period, the number of SH6 spores in the gut of whiteleg shrimp in the SH6 group and the SH6-SH23 group were 5.7×103 CFU gut-1 and 7.7×103 CFU gut-1, respectively.

We studied the arbuscular mycorrhizal (AM) and dark septate endophyte (DSE) fungal associations in five species of potgrown Asparagus (A. aethiopicus, A. densiflorus, A. setaceus, A. racemosus, and A. umbellatus). Root colonization by AM and DSE fungi and AM spore numbers in the soil were assessed. AM fungal diversity indices like species richness, Shannon–Weiner index, Simpson’s index, evenness, and Jaccard’s index were determined.

The diversity of arbuscular mycorrhizal fungi (AMF) is of great interest because of their potential function in ecosystems. Tree peony is an important traditional ornamental and medicinal plant with economic significance. We examined the mycorrhizal status of the rhizosphere of 14 common cultivars of tree peony (Paeonia suffruticosa) in 3 different geographic locations in China.

The effect of soil chemical properties on the diversity and colonization of arbuscular mycorrhiza (AM) varies among ecosystems. This study was conducted to assess and compare the abundance of AM in a rehabilitated forest and a logged-over forest soil using the most probable number and spore number methods.
